1.What is exhaust braking？
2.What does exhaust braking mean?
Install a regulating valve on the engine exhaust pipe, increase the pressure of the exhaust stroke by closing the valve, and use the generated negative pressure to obtain braking force. The so-called exhaust braking refers to turning an engine that was originally a power output device into an air compressor, becoming a power consuming device. Firstly, when the exhaust brake is activated, the fuel injector will stop injecting fuel, but the engine is still working, continuously inhaling fresh air. At the same time, the butterfly valve installed in the exhaust system closes, blocking the exhaust manifold, causing the pressure in the exhaust manifold to reach 4-6 atmospheres. At this point, the power source of the engine is the inertial force that the vehicle continues to slide, rather than the energy generated by the combustion of the mixture. At this point, the engine piston compresses the high-pressure air in the exhaust pipe, continuously consuming the vehicle's kinetic energy to achieve the goal of reducing vehicle speed. The following is the meaning of exhaust braking: 1. Exhaust braking is a type of auxiliary braking for vehicles, commonly known as exhaust braking, also known as engine cylinder braking. Exhaust braking is realized in the engine, many of which are realized by closing the engine exhaust channel, so that the engine piston will be prevented from running by the counter pressure of the gas during the exhaust stroke, which will produce braking effect, so as to achieve the purpose of controlling the vehicle speed; 2. However, there are some restrictions. When using exhaust braking, it is not allowed to shift to neutral or release the clutch, otherwise the exhaust braking will be ineffective and driving accidents may occur; 3. The exhaust braking device consists of an exhaust braking button valve, an exhaust working cylinder, an exhaust braking butterfly valve, and an oil stopping cylinder. The exhaust braking operation is convenient, simple and effective; 4. When driving on ice, snow, and slippery muddy roads, using exhaust braking can reduce sideslip; When going downhill on long slopes, using exhaust braking can reduce the number of service brakes, reduce the temperature rise of the brake drum, and improve the reliability of braking. When using exhaust braking, it can reduce the supply of engine oil and even cut off fuel, saving fuel.
Exhaust braking refers to the setting of a regulating valve on the engine exhaust pipe, which increases the pressure of the exhaust stroke by closing the valve, and uses the generated negative pressure to obtain braking force.
The following is the relevant information:1. The exhaust braking is generally activated by a manual switch. To prevent the engine from stalling during parking and the exhaust braking action during fuel injection, the exhaust braking is automatically released when the accelerator pedal or clutch pedal is pressed. Due to the need to cut off fuel supply during operation, exhaust braking cannot be used for gasoline vehicles.2. The correct use of exhaust brake can greatly reduce the use of service brake (brake), thereby reducing shoe (or disc) wear and greatly reducing the driving safety risk caused by continuous brake overheating of the shoe (or disc).3. The working principle of exhaust braking is that when the exhaust braking is activated, the fuel injection nozzle will stop injecting fuel (only for Euro 3 engines with electronic injection, many old Euro 2/3 engines will continue to supply fuel), but the engine still works, constantly sucking in fresh air. At the same time, the butterfly valve installed in the exhaust system closes, blocking the exhaust manifold, causing the pressure inside the exhaust manifold to reach 4-6 atmospheres, At this point, the power source of the engine is the inertial force of the vehicle that continues to slide, rather than the energy generated by the combustion of the mixture. The engine piston is currently compressing high-pressure air in the exhaust pipe, continuously consuming the kinetic energy of the vehicle's driving, achieving the goal of slowing down the vehicle's speed.2.What does exhaust braking mean?
