Abstract
In engine brakes of the type in which a master piston is reciprocated by an associated internal combustion engine part to hydraulically pressurize hydraulic fluid in a plenum, after which a trigger valve is opened to apply that hydraulic pressure to a slave piston which opens an exhaust valve in the engine to produce a compression release event, an electronically controlled trigger valve is used in place of the conventional mechanically operated trigger valve. The electronically controlled trigger valve can be much simpler and cheaper than the mechanical trigger valve it replaces, and it can also be readily controlled to automatically vary the timing of the compression release events if desired.
