Abstract
The present invention is directed to an engine braking assembly and method for producing a bleeder braking event in an engine having at least one engine valve, at least one engine cylinder, and intake and exhaust manifolds. The engine braking assembly comprises an engine housing, having a hydraulic circuit formed therein; a high-pressure fluid source adapted to store high-pressure fluid therein; a valve for controlling the flow of the high-pressure fluid, in communication with the high-pressure fluid source through the hydraulic circuit; a control device for selectively controlling the valve; and a valve actuation assembly in communication with the valve through the hydraulic circuit, wherein the valve actuation assembly receives the high-pressure fluid through the valve and wherein the hydraulic force created by the high-pressure fluid actuates and holds open the at least one engine valve to produce the bleeder braking event.
