DIESEL EXHAUST BRAKE (ENGINE BRAKING)

The purpose of the exhaust brake (engine braking) fea-
ture is to supply negative (braking) torque from the
engine. Typically, the engine braking is used for, but not
limited to, vehicle towing applications where vehicle
braking can be achieved by the internal engine power,
thereby sparing the mechanical brakes of the vehicle.
