Engine braking is the process by which a vehicle is slowed by the compression of its engine. The throttle closes to idle, but the engine speed remains high, creating a lean burn condition and not supplying enough power to the driveline. The kinetic energy of the vehicle is translated to maintain the engine speed, and lost as friction, pressure and heat. | Engine braking is the process by which a vehicle is slowed by the compression of its engine.
