ABSTRACT:
An improved compression release engine braking system is provided for internal combustion engines having two exhaust valves associated with each cylinder. The slave piston of the compression release brake is relocated so as to register with one of the two exhaust valves and the crosshead assembly is modified so that actuation of the exhaust valve rocker arms will open both exhaust valves in the normal manner during the fueling mode of engine operation while the slave piston of the compression release brake will open only one of the exhaust valves during the engine braking mode of engine operation.
