Abstract:
A system for providing exhaust gas recirculation and compression release braking in an engine, said system comprising:a compression release retarding assembly for supplying energy to actuate at least one exhaust valve assembly to perform a compression release retarding operation;an exhaust gas recirculation assembly for supplying energy to actuate said at least one exhaust valve assembly to perform an exhaust gas recirculation operation;valve actuation means for actuating said at least one exhaust valve, wherein said valve actuating means is capable of actuating said at least one exhaust valve in response to energy from said compression release retarding assembly to perform a compression release retarding operation, said valve actuating means is capable of actuating said at least one exhaust valve in response to energy from said exhaust gas recirculation assembly to perform an exhaust gas recirculation operation; andmeans for independently transferring energy from said compression release retarding assembly and said exhaust gas recirculation assembly to said valve actuation assembly.
