ABSTRACT:
In a compression release engine brake, electrically controlled mechanisms are provided to partly selectively control the positions or motions of the engine brake slave pistons which periodically open the exhaust valves in the associated internal combustion engine when engine braking is desired. The electrically controlled mechanisms can be used for such purposes as controlling the "lash" of the engine brake or controlling the timing and duration of exhaust valve openings. Because these mechanisms are electrically controlled, they can be made to operate substantially instantaneously.
