The engine brake, also known as compression brake, which helps to slow down a vehicle by reducing the power of the engine. Most drivers know only the two classic ways to slow down a vehicle: the pedal and the handbrake. However, moreover, there is also the brake of the engine, which is an important tool for professional drivers, in particular for those who guide trucks and buses, because it can help reduce the wear of the brake and increase safety.
In the following lines we will discuss more details on this maneuver, we will describe in detail what the engine brake means, how to make the engine brake and what are the situations in which its use is required.
In a car with manual gearbox, the compression brake is performed by passing a lower step while driving. The engine brake is a maneuver that is not used by the mechanical car system to slow it down, but the engine power. When the driver releases the accelerator pedal and changes the speed in a lower step, the engine speed increases, which creates a counterpression, slowing down the speed of the car. This technique is commonly used by expert drivers while lowering the steep hills, because it reduces the need for frequent use of mechanical brakes and can help maintain better car control, especially if the road is covered with snow or ice.
However, it is important to remember that excessive use of the engine brake can exercise useless pressure on the components of the propulsion system and the propulsion system. Therefore, it is recommended to use it only when necessary and in combination with the conventional braking system, so that the car remained in the optimal parameters of performance and safety.
Because the market of Car sales He started to be dominated by cars with automatic transmission, it is necessary to know that in their case it is possible to use the engine brake. In the case of this type of car, the engine brake is operated when the exchanger is in driving mode and gradually reduces the speeds, reaching the first gear.
When an engine is in operation, it generates energy by burning fuel in the combustion chamber. This process creates a lot of energy and when the driver releases the accelerator pedal, the engine continues to rotate, generating energy even if the driver does not apply any force.
The engine brake works by limiting the air flow into the engine cylinders, which creates a counterpression that slows down the engine rotation. This consideration is created by closing the engine drain valves during the engine supply stroke, which compresses the air from the cylinders and slows down the engine speed.
The compression brake is commonly used in large commercial vehicles, such as trucks and buses, to help slow down the vehicle when a slope is lowered or in other situations where the driver must reduce the speed without using the brakes.
The operating mechanism of the engine brake
The engine brake works using the engine compression to slow down the vehicle. During the running to the power supply, the engine pistons compress the air from the cylinders, which generates heat and pressure. When the driver activates the engine brake, the system opens the exhaust valves in the upper part of the compression race, releasing the compressed air from the cylinders and slowing down the engine.
The process creates a high pressure wave that moves through the exhaust system, which helps to slow down the vehicle by creating resistance against the engine movement. This process is repeated for each engine cylinder, which helps to slow down the vehicle.
The engine brake is particularly useful in situations where the driver must slow down the vehicle as quickly as possible while driving on a steep slope. The use of the brake of the engine can help prevent overheating and loss of the efficacy of the brake, which can be dangerous for long descents. It is also useful in situations where the driver must maintain a very well control over the vehicle, such as when driving on slippery roads, in ice or snow conditions.
In addition, the use of the engine brake can help reduce the wear of the vehicle braking system, which can help you save money for long -term maintenance and repairs. By reducing the need for a frequent replacement of brake pads, this engine brake can help extend the duration of the vehicle life and improve its general performance.
In conclusion, the engine brake is a useful tool for all categories of drivers, when they are in less favorable road conditions, in particular for drivers who guide large trucks and buses. This helps to slow down the vehicle without using the car mechanical brakes, which can reduce the wear of the braking system and increase safety on the road. By understanding how to effectively use the engine brake and in which situations it is best to do, you can make sure you use this function of the car for its full potential and improve your driving experience.
