What is the correct usage of the exhaust brake?
1 Answers
The correct usage of the exhaust brake is: when the accelerator pedal is at zero position and the fuel injector stops injecting fuel, the exhaust brake will automatically turn off when stepping on the accelerator pedal or clutch pedal. This can prevent engine stalling when stopping and exhaust brake activation during fuel injection. The exhaust brake is a type of vehicle auxiliary braking method, also known as engine braking or cylinder braking, which is achieved within the engine. The working principle of the exhaust brake is: utilizing the vehicle's own kinetic energy to compress air during the intake stroke, and when the piston reaches the top dead center, the exhaust valve is opened through an additional mechanism to discharge the compressed high-temperature and high-pressure gas from the cylinder, avoiding the compression air doing work on the piston during the next power stroke.
