    摘要: A system and method for actuating one or more engine valves to produce an engine valve event is disclosed. The system may comprise: a housing; an accumulator disposed in the housing having a first open end and a second open end; a master piston slidably disposed in a first bore formed in the housing; a valve train element(s) for imparting motion to the master piston; and a slave piston slidably disposed in a second bore formed in the housing, the slave piston in fluid communication with the master piston through a high pressure hydraulic passage, wherein the first open end and the second open end of the accumulator are in communication with the high pressure hydraulic passage to selectively modify the imparted motion.

    摘要: In an internal combustion engine comprising a gas recirculation passage connecting an exhaust manifold to an intake manifold, a compression release valve, and at least one gas pulse created during a first event, a method for retarding the engine comprising the steps of opening the compression release valve, releasing at least one gas pulse into the gas recirculation passage after a first event, redirecting the at least one gas pulse into the intake manifold, and using the at least one gas pulse to increase air charge in a cylinder.
