• About Air Brakes
• Air Brakes Components
• How Air Brake Works
• Air Vs Hydraulic Brakes
• FAQs

When tonnes of weight are moved via heavy vehicles, brakes are among the most crucial components that ensure road safety. While conventional hydraulic braking systems are effective for regular cars, many diesel-powered heavy vehicles rely on air brakes. The system uses compressed air to bring massive moving loads to a complete halt safely.

Let’s explore how the air brakes in heavy vehicles work, their key components and functionalities.

What are Air Brakes in Heavy Vehicles?

Air brakes are a type of braking system that uses compressed air to apply pressure on the brake pads and stop the vehicle. Also known as the compressed-air brake system, it is installed in large heavy vehicles, including trucks, buses, trailers and semi-trailers. Air brakes have advantages over hydraulic brakes, such as more stopping power and better safety against a leak.

What are the Main Components of Air Brakes?

Let’s develop a deeper understanding of the air braking system by learning more about its different components.

Air Compressor

The air compressor is responsible for creating and supplying air pressurise to the system. It continually compresses atmospheric air and maintains the required 100–120 psi pressure in the system.

Air Reservoirs 

These are storage tanks for compressed air. There are typically two types: primary and secondary reservoirs. They store air for use when needed and help maintain brake pressure.

Brake Chambers

These are components that convert air pressure into mechanical force. They contain diaphragms that expand when air pressure is applied to create friction and slow down the vehicle.

Brake Lines and Hoses

These are the conduits that carry pressurised air from the reservoirs to the brake chambers. When conducting regular brake maintenance, check lines and hoses to ensure reliable brake performance.

Quick Release Valve

This valve is used to release brake pressure rapidly, allowing the brakes to disengage when the driver releases the brake pedal. It helps in reducing stopping distances.

Spring Brake Actuator

A crucial component that automatically engages the brakes if there’s a loss of air pressure. It serves as a safety feature to prevent runaway vehicles.

Brake Pedal Linkage

The linkage connects the brake pedal to the air valves and controls the application and release of the brakes.

Brake Control Valve

This valve regulates the amount of air pressure sent to the brake chambers, allowing the driver to modulate braking force. It is one of the most important components of the air brake system in trucks.

Governor

The governor controls the air compressor’s operation. This maintains the appropriate air pressure within the system.

Brake Drums and Shoes (or Brake Discs and Pads)

Air brakes in heavy vehicles either use drum brakes or disc brakes. Drum brakes encompass brake drums and shoes, while disc brakes use brake rotors and pads. These components create friction when pressed together, resulting in braking action.

A driver must be aware of all these components and their functioning to safely drive around heavy vehicles.

How Air Brakes Work

When the driver applies the brakes, the brake valves open and compressed air flows to the brake chambers. The compressed air pushes the pistons in brake chambers, which moves the brake actuators and applies the brakes.

Similarly, when the brakes are released, the brake valves close and decrease the air pressure in the brake chambers. The springs in the brake chambers then return the brake actuators to the released position. However, for proper functioning, check air brake components regularly and add them to your truck inspection checklist.

Air Brakes Vs Hydraulic Brakes: How They are Different

Air brakes and hydraulic brakes are two different braking systems used in various types of vehicles. They have distinct characteristics and applications. Here’s a comparison of the air brake system vs the hydraulic brake system.

Functioning

Air brakes in commercial vehicles use compressed air to actuate the brake components. When the brake pedal is pressed, air pressure is applied to the brake chambers. This applies the force to the brake pads or shows, slowing down the vehicle.

In hydraulic brakes, a fluid transmits pressure from the brake pedal to the brake callipers or wheel cylinders. As a result, braking force is applied and the vehicle slows down. 

Application

Air brakes can generate a substantial amount of braking force, making them suitable for heavy-duty applications. They can handle the braking requirements of large and heavy vehicles effectively.

On the other hand, hydraulic brakes are designed to work efficiently in lighter vehicles. However, their braking force may not be sufficient for extremely heavy loads.

Maintenance

Air brakes generally require less maintenance than hydraulic brakes. They are less prone to brake fade due to heat, and the air pressure system is relatively robust. That said, in case of malfunction or failure, visit these bus repair centres in Dubai or the ones in your respective emirate.

Since hydraulic fluid can overheat, hydraulic brakes are more susceptible to brake fade under heavy usage. Brake fluid must be changed periodically. This is why, hydraulic brakes often require frequent monitoring for leaks and maintenance.

Emergency Braking

Air brakes in commercial vehicles have a built-in safety feature known as a spring brake actuator. It automatically applies the brakes in case of a loss of air pressure. This feature is essential for enhanced safety, especially for heavy-duty transportation.

However, hydraulic brakes do not have an equivalent emergency braking feature. Loss of hydraulic fluid can result in a complete loss of braking capability.

FAQs

Which type of brake is used in heavy vehicles?

Heavy vehicles have air brakes instead of conventionally used hydraulic brakes in regular cars. 

Why do trucks and buses use air brakes?

Trucks and buses usually transport heavy loads, which is why they require air brakes. This braking system produces a substantial amount of braking force, suitable for heavy-duty applications.

How do air brakes work?

An air brake system works with the principles of friction. It creates the required pressure on the brake pistons with the help of compressed air.  When the pressure is applied on the brake pad or shoe, the vehicle safely comes to a halt. The working of air brakes in heavy vehicles is simple physics.

That wraps our overview of the functioning and importance of air brakes in heavy vehicles. Meanwhile, here are some more tips and tricks to control heavy-duty transport. Make sure you’re aware of the RTA laws for heavy traffic before you hit the road.

Whether you’re looking for a new truck or other types of heavy vehicles for sale in the UAE, there are plenty of options available in the market.

• Air Cooling System
• Liquid Cooling System
• Challenges of EV Cooling Systems
• FAQs

Electric Vehicles (EVs) significantly contribute towards greener and more eco-friendly transportation. Unlike conventional ones, EVs are powered by rechargeable batteries, reducing their tailpipe emissions and harmful impact on the environment. Despite having completely different mechanisms, EVs share similar components with conventional vehicles, like cooling systems. In conventional cars, the cooling system caters to the temperature generated during the combustion process. Whereas in EVs, it is used to regulate the excessive heat generated by batteries, HVAC systems and motors. 

Let’s dive a little further into different types of EV cooling systems, their working and their limitations. 

Electric Vehicle Cooling System Types

Internal combustion cars use different types of engine cooling systems to regulate the temperature. Similarly, EVs also have varied cooling systems, including air and liquid cooling systems. Both systems serve similar purposes but differ in terms of efficiency and components used for cooling. 

Here are the complete details of the different types of EV battery cooling systems and their functioning. 

Air Cooling System

As evident from the name, the air cooling system utilises air from the environment to cool down the battery temperature. The principle of convection is used in the air cooling system, where cool air enters the car, circulates around the battery system and exits from the car. 

Since air has low conductivity, the air cooling system is considered less effective. The system is capable of dissipating only a few hundred watts of heat. To increase the efficiency, some manufacturers install an active cooling system that includes fans, heat sinks and cooling liquid. 

Liquid Cooling System

A liquid cooling system uses a liquid coolant like refrigerant or glycol-based coolant to maintain the car’s temperature. The liquid cooling system consists of pipes, a reservoir, a radiator and a pump. The coolant is pumped in the pipes that are wrapped around the battery system and other components that generate heat. The coolant travels through these pipes, absorbing heat and then returning to the car radiator for cooling down. 

The process continues until the car engine is running. In some liquid cooling systems, the dielectric coolant is used that comes in direct contact with the battery cells. This type of liquid cooling is more effective but less safe. That said, it is rarely used in passenger EVs. 

Unlike conventional vehicles, coolant in EVs does not require regular maintenance and can run up to 5 years on one change. In fact, some brands claim that their coolant is enough for a lifetime, exempting drivers from changing it. 

Challenges of EV Cooling Systems

The cooling system is significant for electric car battery maintenance, ensuring optimum performance. However, there are certain limitations and challenges of these cooling systems that need to be considered. 

Leakage

The pipes used in the liquid cooling system are prone to damage. Even the slightest leakage in the pipes can cause coolant to drip, reducing the coolant level gradually. Driving on a low coolant level is not advised as it can lead to some major car problems. In conventional vehicles, driving on low engine coolant levels can cause issues like engine overheating and head gasket leakage.  

Corrosion and Clogging

Corrosions and clogging are common problems associated with liquid EV battery cooling methods. Driving with old glycol-based coolant can cause corrosion and clogging in different parts of the system. It is recommended to change the coolant as instructed in the car owner’s manual.  

Extreme Temperature

EVs are affected by weather, impacting their overall performance and efficiency. The cooling system in modern cars is capable of dealing with extreme temperature changes, but its working can be affected. For instance, in the extreme heat of the UAE, the air cooling system will absorb hot air from the environment, limiting its cooling capacity. 

Ageing

The battery performance deteriorates with the ageing of the vehicle. As batteries get older, a major portion of energy is lost in terms of heat. The increasing heat emissions cause stress on the cooling system, leading to frequent repair shop trips. 

FAQs

Do EVs have cooling systems?

Yes, there are different types of EV cooling systems used to regulate the excessive heat generated by car batteries, transmission and other systems. Aside from a cooling system, some EVs also have a preconditioning feature that helps in regulating car temperature.

Which cooling system works best in electric vehicles?

Both air and liquid cooling systems come with their own pros and cons, but liquid systems are preferred. This is because the air cooling system is less effective in hot and humid climates like that of the UAE. 

Do I have to change the EV coolant?

It varies from vehicle to vehicle, some manufacturers claim that their coolant is enough for the car’s lifetime. Whereas others recommend changing it, generally after five years. 

This was all about different types of EV cooling systems that are currently being used. Continuous improvements and the inclusion of customer-centric features are preparing electric cars for the future of transportation. These vehicles are cleaner and cause less strain on the environment. If you are still driving your old conventional vehicles, it’s time to switch. Browse through these used cars for sale in the UAE and choose an appropriate electric car.

• Coolant in EVs
• Type of EV Coolant
• EV Coolant Replacement
• FAQs

In recent decades, Electric Vehicles (EVs) have stormed the automobile industry, revolutionising the future of mobility. The unconventional electric engine helps eliminate several auto parts that require regular maintenance. However, one thing that is still common in conventional and electric vehicles is the usage of coolant. In conventional vehicles, coolant is required to regulate the temperature, whereas, in EVs, it serves other purposes.

Let’s take a closer look at why EVs use coolant and what are its impact on vehicle efficiency. 

Do EVs Need Coolant?

EVs also produce heat when functioning; however, the heat is significantly lower contrary to a conventional vehicle. Electric cars have lithium-ion batteries that can produce heat. This is why a cooling system is required to cater to the heat produced by batteries, especially when driving in hot temperatures. Here are some other tips to maintain EVs in hot weather that you can leverage. 

The cooling system varies from vehicle to vehicle. Some EVs use an air cooling system, which exempts the need for a coolant. Whereas others use liquid cooling systems that depend on a coolant to reduce the temperature.  

Usage of coolant is necessary to maintain electric car batteries and also to ensure its maximum performance. The liquid cooling system in EVs works more or less similarly to a conventional cooling system. A series of pipes carrying coolant runs around the car battery, which maintains the temperature. The pipe eventually leads to the car radiator, where the coolant’s temperature is reduced prior to sending it back towards the battery.

Besides these cooling systems, some vehicles also have a preconditioning feature that helps in maintaining the car’s temperature.

Type of Coolant EVs Use

The heat production and requirement of coolant in EVs is lower than that of a conventional vehicle. That said, specially manufactured glycol-based coolant is used in electric vehicles. Since the heat generated is lower, a low-conductivity coolant works fine for EVs.

Despite the lower heat, coolant is one of the most important fluids electric cars still need. These fluids are used for lubricating different parts of an electric car, including steering, brakes and transmission. Similar to conventional vehicles, these fluids require regular maintenance to ensure the maximum efficiency of each auto part. However, the frequency of changing fluids varies from vehicle to vehicle and its usage. 

When to Change EV Coolant 

Another advantage of owning an electric car is less frequent change of coolant. EV coolants have a longer lifespan in comparison to conventional ones. Where a conventional coolant should be replaced after every 30,000 km or 24 months, EV coolant can last up to 5 years. 

Some EV manufacturers rolled off cars with a lifetime serving coolant, exempting any need for coolant change. This is only possible because electric cars produce significantly less heat compared to regular cars. Despite the fact that coolants are for a lifetime, it’s better to change the battery coolant every few years to ensure maximum vehicle performance. 

FAQs

Do electric cars have a cooling system?

Yes, EVs have a cooling system that regulates the heat car batteries produce. Although the heat generated is not significant, it still needs to be cooled down. 

Do electric vehicles have coolant or oil?

Yes, electric cars need coolant and oil. The coolant caters to the heat generated by batteries and oil is required for different parts like steering, brakes and transmission. 

Is EV coolant the same as regular coolant?

No, EVs use special coolants that are low in conductivity and are glycol-based. It is recommended not to use EVs and conventional coolants interchangeably. 

How are EVs cooled?

EVs are cooled with the help of air or liquid-based cooling systems. The liquid-based cooling system runs coolant around the car battery to capture the heat. The coolant is then cooled down with the help of a radiator. 

This was all about the usage of coolant in an electric car. The continuous evolution and introduction of customer-centric features are cementing the position of EVs as the future of the automobile industry. Aside from being eco-friendly, modern EVs are equipped with all the necessary features that can compete with a conventional vehicle. That said, if you are still driving an old combustion engine car, it’s time to upgrade. Browse through these used cars for sale in the UAE and pick your EV from an array of options. 

Besides, if you are looking for the latest EV cars, here are some electric cars to look for in 2023.

Whether it’s about revving power or fuel economy, cars with combustion engines rely on many critical components to perform optimally. One of the tiny yet most significant engine parts is the throttle body. From controlling the circulation of air in the engine to optimising the amount of fuel burnt, it has many crucial functions.

Let’s delve into the basics of a car throttle body, its function, common problems, and maintenance.

Throttle Body Function

The throttle body is a butterfly valve that regulates the amount of air entering the engine. Its function is to maintain the air-to-fuel ratio for combustion with the help of a fuel injection system. An efficient air filter is essential for the proper functioning of a throttle body.

How Throttle Body Works

The throttle body works with the accelerator pedal. When you press the accelerator pedal, the throttle shaft rotates, which opens the butterfly valve. This allows more air to enter the engine. Similarly, when the accelerator pedal is released, the throttle shaft rotates back, which closes the butterfly valve. This restricts the amount of air that enters the engine.

The throttle body also plays a role in maintaining a stable idle speed otherwise the vehicle vibrates when idling. It can slightly open the throttle plate to allow a small amount of air into the engine, preventing stalling. Here are some of the key reasons why a car’s engine keeps stalling. 

Where is Throttle Body Located

The exact location of the throttle body may vary depending on the make and model of the car. That said, there is a consistent placement pattern. The best way to locate it is to follow the air intake system from the air filter housing. The throttle body is typically attached directly to the engine’s intake manifold.

Components of a Throttle Body

The throttle body in a car’s engine performs its crucial functions with the help of the following components. 

Throttle Plate

The throttle plate is a flat, circular or oval-shaped disc positioned inside the throttle body. Connected to the throttle shaft, its position can be controlled electronically or mechanically. The throttle plate opens and closes to control the amount of air entering the engine.

Throttle Shaft 

The throttle shaft is the rod or spindle that connects the throttle plate to the actuation mechanism. It can either be connected to the accelerator pedal cable or an electronic motor. A throttle shaft is responsible for precise control of the throttle plate’s position.

Housing

The throttle body housing is the outer casing that houses the throttle plate and other internal components. It is typically made of metal or plastic and is designed to withstand the heat and vibrations in the engine bay.

Idle Air Control Valve

In some cases, throttle bodies have an idle air control valve (IACV). This valve allows a small amount of air to bypass the closed throttle plate, maintaining a stable idle speed.

Throttle Position Sensor

The throttle position sensor or TPS is mounted on the throttle body and monitors the position of the throttle plate. It sends signals to the engine control unit (ECU) to provide information about throttle position, which is crucial for fuel injection and engine management.

Gaskets and Seals

These components are used to create a tight seal between the throttle body and other crucial intake system components. Gaskets and seals prevent air leaks that could disrupt engine performance. To learn more about the types of gaskets in a car engine, read here.

Mounting Bolts

Throttle bodies are typically secured to the intake manifold or engine with mounting bolts or screws.

Signs of a Bad Throttle Body

Since the car throttle body directly impacts the performance and fuel efficiency, the signs of it going bad are quite prominent. Here are a few common things to look out for.

Check Engine Light

One of the first few bad throttle body symptoms is check engine light. As soon as the problem occurs with throttle signals sent out by TPS, check engine light illuminates. Make sure you’re aware of all the reasons why the check engine light is on.

Rough or Uneven Idle

When the throttle body is malfunctioning, it is unable to maintain a consistent airflow when idling. This can be one of the reasons for rough or uneven idle, where the engine revs up and down erratically.

Poor Throttle Response

Carbon deposits in the engine cause the throttle plate to become stuck in the closed position, This results in delayed or erratic throttle response when the driver presses the accelerator pedal. In case of experiencing a poor throttle response, also check for these symptoms of bad throttle positioning sensors.

Strange Noises 

Sometimes, a faulty throttle body can produce unusual noises, such as hissing, whistling, or clicking sounds. Never ignore these types of car noises and sounds should never be ignored. They can indicate air leaks or mechanical issues, which should be promptly addressed. 

Difficulty Starting

Difficulty in engine starting is also among the common bad throttle body symptoms. It is due to the insufficiency of air in the combustion chamber, which hinders or delays the ignition.

FAQs

When to clean the throttle body?

A regularly maintained throttle body performs well and is less prone to the aforementioned symptoms. On average, it is recommended to clean the throttle body every 120,000 kilometres. However, it is preferable to refer to the car owner’s manual for necessary instructions.

Can I use carb cleaner to clean the throttle body?

For throttle body cleaning, it is recommended to only use a throttle body cleaner formulated specifically for the purpose. It is better not to experiment with different types of cleaners for temporary convenience. However, make sure to follow these steps for DIY throttle body cleaning.

Can throttle body cause rough idle?

Yes, rough idle is one of the prominent signs of a bad throttle body. However, if you can’t let the carbon deposits build up on it, the throttle body will keep performing optimally. Preventing rough idle is among the key benefits of throttle body cleaning.

This was everything you should know about the throttle body and its functioning. To know about your car, it is important to be aware of all the important engine parts and how they work.
