The use of engine brake is to lift the accelerator pedal, but not from the engine, the use of the engine compression stroke compression resistance, internal friction and intake and exhaust resistance to the drive wheel to form a braking effect.
Frequency, to avoid the use of brakes for a long time, resulting in brake friction plate temperature rise, so that the braking force decreased, or even lose its role; Third, the speed is always limited to a certain range, is conducive to timely deceleration or parking to ensure traffic safety
There are three salient features of the engine brake: First, due to the role of the differential, the braking torque can be evenly distributed on the left and right wheels, reducing the possibility of skidding, flicking; the second is to effectively reduce the use of foot brake
