Abstract
An engine braking system includes a pump associated with a source of fluid, the pump supplying pressurized fluid to fuel injectors associated with the engine. An electronic controller is associated with the engine and determines a desired engine braking level as a function of various engine operating conditions and operator inputs. The engine controller produces a pump signal as a function of the desired engine braking level.
