• Pros and Cons
• FAQs

Parking a vehicle can be a strenuous job for many drivers, especially when parallel parking. From measuring the distance to coordinating the mirror and gears, parking requires experience. To cater to this, automobile brands have launched self-parking or autonomous parking features. The self-parking feature autonomously parks the vehicle into the parking space without the driver’s input. That said, self-parking can reduce any potential chances of accidents during parking. 

Let’s take a closer look at self-parking cars, their working and their benefits in more detail.

Cars with Self-Park Technology

Self-parking technology is one of the most significant modern car safety features. The autonomous parking feature takes complete control of the vehicle and parks it accurately without human intervention. 

Discussed below is how self-parking cars work, but first let’s learn about the different types of self-parking cars. 

Types of Self-Parking Cars

Based on the level of automation, self-driving cars can be divided into three different categories.

Steering Assist

As evident from the name, the steering assists only controls the steering wheel while the driver has to change the gear. In steering assist, an alert illuminates on the instrument cluster that instructs drivers to lose control of steering and accelerate, reverse or apply brakes when needed. 

Parking and Exit Assist

The parking and exit assist is similar to that of the steering assist. The vehicle will autonomously control the steering and instruct drivers to park the car. Additionally, it guides drivers to safely exit the vehicle after parking to avoid any accident. 

Autonomous Parking

Autonomous parking is the most advanced version of self-parking cars, in which the vehicle is completely parked by the system without the driver’s instruction. The autonomous system takes complete control of the vehicle and parks in space accurately.  

How Self-Parking Work

The self-parking cars work in collaboration with a car computer and different car parking sensors. Drivers are only required to stop the vehicle next to a parking spot and turn on the autonomous parking feature. 

Once the feature is turned on, the car will automatically steer itself into the parking spot. However, after parking, the driver has to engage the parking brake and lock the vehicle.

Pros and Cons of Self-Parking Cars

This was all about the function and different types of self-parking features. However, before you opt for self-parking cars on the basis of the above-mentioned information, let’s learn some pros and cons of driving a self-parking car.

Cons

• The autonomous feature only works in ideal road conditions and will park vehicles if the spot is properly paved and free from bumps.
• Extreme weather conditions such as heavy rainfall or dust storms can affect the efficiency of self-parking cars.
• Cars with self-parking technology are unable to read the parking signs and may park the vehicle in a reserved parking spot such as parking for people of determination or electric cars. 

Self-parking Vs Park Assist Feature in Cars

The self-parking feature and park assist system are often confused with each other. The park assist system in cars is a type of self-parking feature, but it is not completely autonomous. The park assist feature might need some assistance from the driver to accurately park the vehicle. 

On the contrary, the self-parking feature is completely autonomous and can park a vehicle without the driver’s assistance. The level of autonomous parking depends on the automobile manufacturer and car model.

FAQs

Is Park Assist and Self Parking the same feature?

No, park assist only helps drivers when parking the vehicle normally. For instance: it will reverse the car or change the gear automatically. However, the self-parking cars can park themselves without the drivers’ assistance. 

Can cars park themselves without a driver?

Yes, modern vehicles are equipped with self-parking features, which allow vehicles to park automatically without human intervention. 

Can my SUV park itself?

Yes, if your SUV has a self-parking feature, it can park itself without your assistance.

Here we conclude our guide on self-parking cars, their types and function. The self-parking, whether it is park assist or fully autonomous parking, aids drivers in parking a vehicle conveniently. The vehicle’s ability to manoeuvre in the parking spot reduces any potential chances of accidents during parking. Therefore, if you are still driving your old car, it’s time to switch to a more advanced one with a self-parking feature.

What You’ll Need

• Full Fuel Tank: Start with a filled fuel tank to ensure accurate measurements.
• Odometer Reading: Your vehicle’s odometer displays the total distance travelled by your car.

Step-by-Step Guide to Calculate Car Mileage

Record Initial Odometer Reading

Begin by noting down the current odometer reading. This reading also represents the total distance your car has travelled up to this point.

Drive Normally

Use your vehicle as you typically would, without making any drastic changes in your driving habits. This step also ensures that your mileage calculation reflects your regular driving patterns.

Refill the Tank

Once your fuel level has significantly decreased, refill the fuel tank to its maximum capacity. Make sure to note the exact amount of fuel added during this refill.

Record Final Odometer Reading

After refilling the tank, record the new odometer reading. Moreover, this reading represents the total distance your car has travelled after driving with the fuel from the second fill-up.

Calculate Total Distance Travelled

Determine the total distance your car travelled during this period by subtracting the initial odometer reading from the final odometer reading. Use either miles or kilometres, depending on your preference and the unit of measurement displayed on your odometer.

Calculate Fuel Consumed

Calculate the fuel consumed during this period by subtracting the fuel level after the second fill-up from the fuel level after the first fill-up. Make sure to use consistent units for fuel measurement (gallons, litres, etc.).

Calculate Mileage: Now you can calculate your car’s mileage using the formula appropriate for your region:

1. For Miles Per Gallon (MPG): Mileage (MPG) = Total Distance Travelled / Fuel Consumed
2. For Liters Per 100 Kilometers (L/100km): Mileage (L/100km) = (Fuel Consumed / Total Distance Travelled) * 100
3. Interpret the Result: The calculated mileage value will tell you how many miles (or kilometres) your car can travel on a single unit of fuel. Hence, the higher the mileage value, the more fuel-efficient your vehicle is.

Remember that calculating mileage accurately requires consistent units of measurement (e.g., miles for distance and gallons for fuel) and accurate readings from your odometer and fuel gauge. Regularly calculating and monitoring your car’s mileage can help you make informed decisions about your driving habits, maintenance routines and overall vehicle efficiency.

• What is a PCV Valve in a Car
• Symptoms of a Bad PCV Valve
• How to Maintain PCV Valve
• FAQs

Internal combustion engines are by far the most common type of engine used in vehicles. These engines burn fuel which generates heat energy. That said, the excessive heat energy and gases are flushed out from the engine through the exhaust system. However, a certain proportion of gases pass the exhaust system and enter different parts of the engine. This is when the Positive Crankcase Ventilation (PCV) valve comes into the picture. 

Let’s dive a little deeper into the purpose and significance of PCV valves in cars. 

What Is a PCV Valve in a Car

Crankcase is a car engine part responsible for holding engine oil. Therefore, the gases pass by the exhaust system and enter into the crankcase and mix with motor oil leading to multiple issues. For instance, the mixing of oil and gas inside an engine can create a slimy material known as engine sludge affecting the overall efficiency of an internal combustion engine. 

The gases gathered in the crankcase majorly comprised unburned fuel. That said, the PCV valve in the crankcase absorbs and recirculates these gases to be used in the combustion process again. In this manner, it not only prolongs the engine life but also reduces the carbon footprint of a vehicle.

The process was initially used in military vehicles and was later introduced in conventional cars during the 1960s. Considering its impact on emissions levels, the PCV valve has become a standard in all automobiles. 

Now that you are aware of what is a PCV valve on a car let’s move towards its functioning. 

PCV Valve Function

The PCV valve’s purpose is to emit excessive gases from the crankcase and reuse it in the combustion process. The valve absorbs all the gases deposited in the crankcase and redirects these gases to the air intake tract. The air intake tract is used to absorb fresh air from the environment for combustion.

The gases supplied by the PCV valve mix with the fresh air making a perfect combination for combustion. The PCV valve continued to recirculate the air till the engine kept running. 

Symptoms of a Bad PCV Valve

PCV valve malfunctioning does not directly impact driving, but it creates multiple underlying issues. Drivers might face issues like engine misfiring or oil leakage when the PCV valve malfunctions. 

Following are some common symptoms that will answer how to know if a PCV valve is bad. 

Hissing or Whistling Sound

The car engine will make a hissing or whistling sound when a PCV valve malfunctions. When gases are not flushed out, it creates excessive pressure inside the crankcase creating small cracks. In worst-case scenarios, it can result in a blown head gasket. When gases under high pressure are released from these cracks, it creates a hissing or whistling sound.   

Poor Fuel Economy

A bad PCV valve can disrupt the air-to-fuel ratio of an engine affecting the combustion process. Inadequate combustion requires more fuel and generates less energy leading to poor fuel efficiency. 

Aside from bad PCV valves, here are some other reasons for high fuel consumption that drivers must look for. 

Oil Leaks

The clogged valve restricts the cylinder’s blowback pressure stressing out the crankcase. After certain pressure, the crankcase leaks resulting in oil leakage from the engine. 

Smoke from Exhaust

When the PCV valve stops functioning, it causes oil leakage allowing it to enter the combustion chamber. The presence of oil in the combustion chamber can be recognised by black smoke from the exhaust. 

Engine Misfiring

Aside from the above-mentioned symptoms, in some cases, engine misfiring is also considered a symptom of a bad PCV valve. Modern vehicles can even illuminate engine check light warning driver regarding a potential flaw in the valve. 

How to Maintain PCV Valve

PCV valves, unlike other engine parts, do not have expiry or need to be changed after covering a certain distance. However, these valves are generally made from rubber or plastic and are prone to damage.

• The first step in maintaining a PCV system is to inspect it physically. Check all the hoses, o-rings, grommets and fittings. In case any part is brittle or damaged, change it immediately. 
• Some PCV valves have mesh filters that should be cleaned regularly. Generally, it should be cleaned after driving 30,000 to 80,000 kilometres. 
• In case the filter is completely damaged or clogged, it’s recommended to replace it. You can replace it at home, but it is suggested to consult with a mechanic. 

FAQs

What does a PCV valve do?

The PCV valve works as an exhaust system and flushes out all the excessive gases trapped inside the crankcase. These gases are reused by the vehicle for combustion. 

How much oil can a bad PCV valve burn?

A bad PCV valve does not burn the engine oil; rather, it causes leakage in the engine through which the oil seeps out. The amount of oil seepage depends on the size of the leakage and damage.

How often to replace the PCV valve?

The replacement of PCV valves varies from vehicle to vehicle. However, ideally, it should be replaced after every 80,000 km.

This was all about the PCV valve, its working and its significance in a vehicle. Internal combustion engines are dependent on multiple smaller components to function properly. Therefore, the malfunctioning of even a smaller auto part can affect overall performance. That said, when buying a used car for sale in the UAE, make sure it has a well-maintained and properly functioning combustion engine. 

Besides, if your current vehicle engine is causing trouble, read through our blog on whether it is better to repair or replace the engine and make your decision.

Buffing a car is a way of showing appreciation for your vehicle. In addition to car maintenance and its overall cleanliness, car buffing gives your vehicle a sleek, radiant and shiny look. The process rejuvenates your car’s appearance by eliminating the wear and tear it accumulates over the changing seasons. Over time, cars gather dirt and debris that eventually impacts the car paint. Nevertheless, buffing a car takes care of this problem. 

How to Buff Your Car 

Buffing a car goes beyond cosmetic appeal. It plays an important role to maintain the condition and value of the vehicle. Let’s go through some important tips for car buffing. 

Wash Your Car

Park your vehicle in a shaded area, ensuring that the car’s surface is cool. This action prevents the formation of soap stains on the car’s exterior. Subsequently, position the mix of soap and water solution in a gallon-sized bucket. For better outcomes, use car wash-specific soaps. Go through the instructions on the soap’s packaging to determine the appropriate amount of soap to dispense. Then, immerse a sizable sponge in the soapy water.

Retrieve the sponge from the water-filled container, gently squeezing out around fifty percent of the excess liquid. Place the sponge onto the car’s surface, initiating the washing process. 

Move the sponge in circular motions, encompassing the entire car body. Take special care to address recesses and gaps where dirt might be lodged. Begin from the uppermost part of the car and gradually progress downward. Once the vehicle has been cleaned thoroughly, rinse off the soap remnants with a hose. Here is a guide to car wash in Dubai.

Choose a Buffer

A high-speed buffer yields optimal outcomes by eradicating surface imperfections and buffing car scratches, resulting in a brilliant shine. That said, mastering its usage requires training. Improper application can lead to permanent damage, like swirls and scratches that strip the paint.

For impressive results with minimal effort, a random orbital buffer is an option. It offers a pleasing sheen and doesn’t demand training. While it may not eliminate all damage, it delivers a great shine. Additionally, it uses less compound, making it cost-effective. Nonetheless, the results might not be as durable as those with a high-speed buffer.

Then, manual buffing is also a cost-effective choice, albeit the most labour-intensive, providing comparatively fewer effective results. It’s time-consuming and might yield an uneven finish with shorter-lasting results compared to other methods.

After selecting a buffer, acquire a polishing or compound product suited to your car’s needs. Compound addresses deep scratch repair and helps restore faded car paint. On the other hand, polish enhances existing paint. Besides, a DIY car paint correction also helps improve the paint.

Tailor your choice to the car’s make, model and condition. Both products can be used with the buffer. Seek product recommendations from trusted sources like friends or reputable car enthusiasts.

Apply Polish to the Buffing Pad

When using a fresh pad, spritz a small amount of detailer on it before putting on the polish. Add some lubrication and dispense four small portions of polish, akin to the size of peas, onto the pad. Ensure that you shake the polish bottle adequately before application.

The easiest approach for polishing your vehicle entails working in segments. Set up a space that measures two by two feet. Before buffing a car, gently press the pad onto the section you’re about to treat. Subsequently, switch the buffer to its lowest setting and delicately spread the polish across the designated region. 

At this stage, your goal isn’t to buff the car’s exterior; instead, you’re merely spreading a thin layer of polish.

Start Buffing 

Following the application of the spread polish to the designated area, it’s time to engage in buffing. If an orbital buffer is in use, adjust the power setting to five or six. Gently press down on the buffer’s top with your hand while operating it. Proceed to move across the section using horizontal lines that overlap by 50%. Subsequently, repeat this motion in a vertical direction.

Upon completing both vertical and horizontal buffing, consider this a single pass. After executing three to four passes on the same area, your task is accomplished. On average, each area requires three to four minutes for completion. 

Avoid exerting excessive pressure on the buffer. As you buff, you’ll notice the polish taking on a chalky appearance—let this transformation signify that the polish is effectively performing the work.

Wipe it Down

After the process of buffing a car is complete, some remnants of the polish might remain, but there’s no need for concern. Use a microfibre cloth to eliminate the residue by gently rubbing it away using either circular motions or straight vertical lines. Using a microfibre cloth is among the important tips for car cleaning.

Change or Clean Pads

For those aiming to maintain their vehicle’s polish, it’s advisable to replace buffing pads every few months. However, irrespective of a pad’s age, it’s necessary to clean it after finishing each section or two.

A straightforward approach to cleaning the pad involves setting the buffer to a moderately low setting and brushing it with a toothbrush that has soft bristles. You’ll recognize the effectiveness of this process as you observe accumulated debris vanishing.

FAQS

What kind of soap should be used to wash a car before buffing it?

A mild soap should be used to wash the car exterior before buffing it. For better results, use a car wash-specific soap. Go through the instructions on the soap’s packaging to determine the appropriate amount of to dispense.

What should be done after car buffing?

An alternator is a crucial part of a car battery. It converts chemical energy into electrical energy for a car’s running. It also powers other car components and accessories. However, at times, an alternator can become overcharged and malfunction. It occurs due to numerous reasons. That said, we have compiled a list of different causes of alternator overcharging and how to fix it. 

But first, we will go through the symptoms to help identify this problem in car alternators. 

ALTERNATOR OVERCHARGING SYMPTOMS 

An alternator overcharging means it generates more than the required voltage. A 13.5 or 14.4-volt output is a standard for alternators. At times, some car parts malfunction, indicating such problems. It is easy to confuse these symptoms with a bad car battery or an alternator. To clear up this uncertainty, let’s go through the common symptoms of an overcharging alternator.  

Flickering Dashboard Lights or Headlights

One might notice flickering headlights or dashboard lights due to excessive power output. It happens when the alternator pumps more charge, making the lights too bright and then back to normal. 

Shortened Bulb Life

An overcharging alternator affects car electronics. Since there is too much power supplied to electric components, it puts an increased strain on the components. As a result, they wear out faster. Car bulbs have a different average life span, depending on their type. These include:

• Halogen: 450 to 1,000 hours
• HID: 6,000 to 24,000 hours
• LED: 30,000 to 50,000 hours

High Voltage Readings

Another sign of alternator overcharging is high voltage readings. A voltage reading above 14.5 volts on the vehicle’s voltmeter or dashboard gauge indicates overcharging. When voltage ratings are unbalanced, they also create an open loop fault in cars.

Strange Smells

Overcharging leads to excessive heat in the alternator. As a result, a burning smell emanates from the engine compartment. It indicates the formation of hydrogen sulphide gas and that battery is no longer safe to use. 

Battery Damage

Over time, an overcharging alternator damages the vehicle’s battery. Excessive voltage causes the battery to overheat, dry out and have a reduced lifespan. It also causes the battery to corrode and one might notice a bulge in the battery. This will also lead to the car battery not charging.

Battery Warning Light

Many modern vehicles have a car battery warning light on the dashboard. If this light is illuminated while driving, it could indicate an issue with the charging system, including potential overcharging.

How to Test an Overcharging Alternator? 

It is important to confirm that the alternator is indeed the problem if the car shows the above-mentioned symptoms. Therefore, here are the steps on how to test an overcharging alternator:

• Disconnect the battery cables to prevent any sparks from occurring while testing the alternator.
• Set the multimeter to DC voltage with a range set to 20 volts or more.
• Touch the red probe of the multimeter to the positive battery terminal.
• Touch the black probe of the multimeter to the negative battery terminal.
• Start the engine and let it run for a few minutes.
• The multimeter should read between 14.2 and 14.7 volts. If the reading is higher than 14.7 volts, then the alternator is overcharging.
• Turn on the headlights and other electrical accessories. The multimeter reading should not change significantly. If the reading does change, then there may be a problem with the alternator or the electrical system.
• Turn off the engine and reconnect the battery cables.

ALTERNATOR OVERCHARGING CAUSES

Now we are aware of the common symptoms of alternator overcharging which lead to different issues such as a car dying while driving. Let’s learn the common causes.

Voltage Regulator Malfunction

The voltage regulator is a critical component of the charging system in a car. It regulates the output voltage of the alternator to power the vehicle’s electrical systems within the required range. If the voltage regulator fails, it can cause the alternator to generate excessive voltage, leading to overcharging of the battery. This results in damage to the car battery and other electrical components.

Wiring Issues

The connection between the alternator and the battery is crucial for the proper functioning of the charging system. If the connections are loose or corroded, it creates a resistance in the circuit, causing voltage fluctuations. These fluctuations cause the alternator to produce higher voltage levels than necessary, resulting in overcharging. 

Faulty Engine Control Module (ECM)

The Engine Control Module (ECM) controls various aspects of the vehicle’s electrical system, including the alternator. It might malfunction or send incorrect signals to the alternator. As a result, a faulty ECM causes overcharging.

Problems With the Car’s Electrical System

The alternator’s voltage output is influenced by the demand from the vehicle’s electrical system. If there’s a malfunction or excessive demand from various components like car headlights, it causes the alternator to produce more voltage than required.

Short Circuit in the Alternator 

A short circuit within the alternator’s internal components can disrupt the normal flow of electrical current. It also causes irregular voltage output leading to damage in car computers. If certain parts of the alternator become short-circuited, it leads to overcharging of the battery. Moreover, short circuits can occur due to wear and tear, manufacturing defects, or damage caused by external factors.

Bad Alternator Bearing

The alternator contains various internal components, including bearings that allow the rotor to spin smoothly. If one of these bearings goes bad, it causes the alternator to spin irregularly or produce excessive friction. This leads to alternator overcharging. In addition, a failing bearing might produce unusual grinding or whining sounds.

ALTERNATOR OVERCHARGING FIXES

There are two practical ways to fix an overcharging alternator. They include the following methods. 

Replace the Voltage Regulator

Here’s how you can do so. 

• Begin by disconnecting the negative (black) cable from the battery to ensure safety and prevent any electrical mishaps.
• The voltage regulator is usually located on the alternator itself. It might appear as a small box attached to the back of the alternator. In some cases, especially in older vehicles, the voltage regulator is a separate component mounted elsewhere in the car.
• Use the appropriate car mechanical tools to carefully remove the screws or bolts holding the voltage regulator in place.
• Ensure that the new voltage regulator is the correct type for the car’s make and model. Align the new regulator with the mounting holes and secure it in place using the screws or bolts removed earlier.
• Reattach the negative (black) battery cable to its terminal. This will complete the replacement process.

Replace the Alternator 

If the regulator is a functioning problem, then the problem lies within the alternator. Here’s how to replace an alternator with these steps. 

• As with the voltage regulator replacement, start by disconnecting the negative (black) cable from the battery.
• Locate the alternator in the vehicle’s engine bay. One or more bolts are securing it in place. Using the appropriate tools, carefully remove these bolts and set them aside.
• The alternator is connected to the electrical system through a series of wires. Disconnect these wires, making sure to note their locations for reconnection.
• With the mounting bolts and wiring disconnected, remove the old alternator from its position.
• Position the new alternator in the same orientation as the old one and secure it with the previously removed mounting bolts.
• Reconnect the wires to the new alternator in the same locations from which they were removed earlier.
• Tighten the mounting bolts to the manufacturer’s recommended torque specifications. This ensures that the alternator is properly secured in place.
• Finally, reattach the negative battery cable to its terminal.

Apart from the above-mentioned methods, it is suggested to seek professional advice. Also, always refer to the vehicle’s repair manual for specific instructions and safety precautions. Regular maintenance of the car battery, alternator and electrical system also helps prevent issues like overcharging.

When it comes to automotive lighting technology, headlights play a crucial role in ensuring driver safety and enhancing the overall driving experience. Over the years, two primary car headlight types have dominated the market: projector headlights and reflector headlights. Both have their unique advantages and disadvantages, but which one is better? Following we will delve into the intricacies of projector vs reflector headlights to help you make an informed decision.

However, before that, you must understand the difference between projector vs reflector headlights, how they work and their basic components.

Understanding Projector Headlights

You can find different types of car headlights that can help you with safe driving. However, projector headlights are a more modern and advanced form of automotive lighting. They are also characterised by their distinct design, featuring a lens system that focuses and directs the light beam. The basic components of a projector headlight include:

• Bulb: The light source, typically a halogen, HID (High-Intensity Discharge), or LED bulb, emits the light that will be directed by the projector assembly.
• Reflector: This component gathers and focuses the light emitted by the bulb onto a specific point.
• Lens: The lens is a key element of the projector assembly. It works to further focus and shape the light emitted by the bulb and reflector, allowing for precise light distribution on the road.
• Cutoff Shield: One of the defining features of projector headlights is the presence of a cutoff shield. This shield helps create a distinct cutoff line in the light beam, preventing excessive glare for oncoming drivers. This feature also enhances safety by reducing the risk of blinding other motorists.

How Projector Headlights Work

When the bulb emits light, the reflector gathers and focuses this light towards the lens. The lens then refracts and focuses the light even further, allowing for better control over the light beam’s shape and direction. Moreover, the inclusion of a cutoff shield ensures that the light is directed downwards and prevents it from shining too high, reducing glare for oncoming traffic.

Advantages of Projector Headlights

Knowing the advantages and importance of car headlights in the UAE is important for a safer driving experience. This is why, we have compiled some advantages of projector headlights used in a vehicle.

Understanding Reflector Headlights

Reflector headlights are a traditional type of automotive lighting technology that has been used for many years in vehicles. They operate using a simpler optical system compared to projector headlights. Besides, in reflector headlights, the primary focus is on reflecting and scattering light in a way that provides illumination for the road ahead.

The main components of a reflector headlight include:

• Bulb: Similar to projector headlights, a light source such as a halogen, HID (High-Intensity Discharge), or LED bulb is used to emit light.
• Reflector Housing: The reflective housing is a bowl-like structure that surrounds the bulb. Its inner surface is designed to scatter and reflect the emitted light in various directions.

How Reflector Headlights Work

When the bulb emits light, the reflector housing is strategically shaped to direct the light outward and onto the road. The shape and contour of the reflector cause the light to bounce off its surfaces, creating a scattered light pattern that illuminates the surrounding area.

Advantages of Reflector Headlights

The advantages of reflector headlights include:

Simplicity

Reflector headlights have a simpler design and are generally easier to manufacture and install.

Wider Availability

Many older vehicles are equipped with reflector headlights, making replacement parts more readily available.

Car idling refers to a stationary position when the engine’s running without any load applied to it. When a car idles, the engine speed must be in the optimal range, i.e. 600 to 900 RPMs. However, if it’s higher or lower than the manufacturer’s recommended range, you may encounter a crucial problem. What RPM should a car idle at? How does it impact engine performance?

Let’s learn more about the ideal RPM when a car idles and what are the causes behind lower or higher engine speeds.

WHAT RPM SHOULD MY CAR IDLE AT?

The ideal idle RPM value is specific to each car’s make and model. It depends on various factors, including engine design, fuel type and environmental conditions. Although the normal RPM of an idle car ranges from 600 to 900 revolutions per minute, some engine problems can be a reason behind RPM fluctuations while driving or idling.

When the RPM falls out of range, it can be concerning for drivers. Commonly, an engine revs higher when warming, but if the RPM is higher after the engine temperature is normal, it might be a crucial problem.

Let’s learn about the vehicle RPM before diving into what RPM should a car idle at.

WHAT IS A CAR RPM?

RPM stands for Revolutions Per Minute. It refers to the number of times the engine’s crankshaft completes one full rotation in a minute. The RPM is an essential parameter to monitor the engine’s speed. Also, it helps drivers determine the appropriate gear and throttle position for optimal performance and fuel efficiency.

Most cars have a tachometer on the dashboard, which displays the current RPM, allowing the driver to monitor the engine’s status. It displays numbers from 1 to 10. You can multiply it by a thousand. Speaking of that, the tachometer shows you a range from 0 to 10,000 revolutions per minute.

When a car is idle, the RPM should be between 500 and 900. Typically, one digit is divided by two bars. RPM should be less than one on the tachometer when idling.

SYMPTOMS OF IDLE CAR RPM ISSUES

Issues with idle car RPM can manifest through various symptoms. A higher or lower RPM at idle can indicate potential problems with the engine or other related components. RPM falling out of range at idle is an obvious symptom. Here are a few more signs that indicate a problem with engine speed.

CAR JERKS

Rough RPM can be a reason for car jerks while accelerating or braking. It could be due to an inconsistent air-fuel mixture or misfiring engine cylinders.

JUMPY ACCELERATION

Idle RPM problems can sometimes affect the car’s performance during acceleration. A driver may feel a sluggish acceleration caused by several problems. For instance, bad spark plugs, fuel delivery issues or a clogged fuel or air filter can cause hesitation when accelerating.

STALLING ENGINE

The engine might stall or shut off unexpectedly when idling. It can be due to the heavy load on the engine when it is too cold. However, it may not happen in the UAE due to hot weather conditions.

Therefore, finding out the reasons behind car engine stalling becomes essential. You can use the onboard diagnostic (OBD) scanner, or the tachometer on the dashboard will tell the RPMS values.

Other symptoms can be the check engine warning light on the dashboard. Also, the engine can consume more fuel due to extra load.

CAUSES OF HIGHER OR LOWER IDLE CAR RPM

Several factors can cause the idle RPM to be higher or lower. While the normal RPM range at idle is 600 to 900, older car models can rev up to 1200 RPM. Here are the problems that can cause a car’s idle RPM to fluctuate higher or lower.

FAILING IDLE AIR CONTROL VALVE

The idle air control valve controls the amount of air that enters the engine when the throttle is closed. When the car’s idle RPM goes high or low, it is a symptom of a malfunctioning idle air control valve. A bad IACV can lead to erratic or incorrect airflow, resulting in fluctuations in RPM.

DAMAGED THROTTLE BODY POSITION SENSOR

The throttle body controls the amount of air that enters the engine. It is a sign of a damaged throttle body position sensor that doesn’t regulate the airflow properly. For that reason, it leads to irregular idle RPM. It is often a result of a clogged air intake or cracked intake tube.

FAULTY MASS AIR FLOW SENSORS

The MAF sensor measures the amount of air entering the engine and sends this data to the engine control unit (ECU). When the RPM of an idle car goes higher, it may be due to the bad MAF sensor causing the rough idling.

VACUUM LEAK

Another cause of rough car idling is vacuum leaks. It occurs due to unintended gaps or cracks in the engine’s intake system. When the car doesn’t idle at the normal RPM, you can detect the car vacuum leaks and fix the issue to avoid other problems popping up. These leaks happen due to certain after-market modifications to the engine, exhaust, or intake system that can affect the engine’s idle RPM. 

MALFUNCTIONING ECU

Car computers can also malfunction. The ECU controls various engine parameters, including idle RPM. The engine control unit may not send or receive accurate signals, causing higher RPMs when the car idles. That said, it can also cause engine surge when the vehicle is idling.

FAQS

SHOULD MY RPM BE AT 1 WHEN PARKED?

It should be between 600 to 900 revolutions per minute. As discussed above, an RPM tachometer typically shows a value from 1 to 10. Therefore, it should be lower than 1.

IS IT NORMAL TO IDLE AT 1500 RPM?

1500 revolutions per minute are way above normal. Older engines can rev up to 1200 RPM to warm the engine. However, if the engine has already warmed up and it still revs higher, it may be due to the above-discussed reasons. 

This was all about what RPM should a car idle at. These values can fluctuate when starting the vehicle as the engine is cold and requires more load. However, if it surges after that when the car idles, you may be facing some common car problems. Therefore, when you are sifting through the options for used cars for sale in the UAE, you must check the vehicle idling.
