LOST MOTION SYSTEM AND METHOD FOR FIXED-TIME VALVE ACTUATION

摘要

This invention relates to a system and method for one or more valves for driving in the normal internal combustion engine, will. In particular, the present invention provides a system and method for driving a right of one or more engine valves are switched between the second operating mode for selectively providing a first operating mode and the auxiliary event valve actuation for providing a main event valve actuation relates to. The system comprises a housing 302 having a bore therein; A piston assembly slidably disposed within the bore, said piston assembly comprising a master piston and a slave piston (130/140); Means (100) for transmitting the movement to said piston assembly; Control valve 320; Providing a low-pressure fluid to the control valve 320, a hydraulic passage (314) connected to the control valve 320 for enabling a second mode of operation. ;
