Abstract

A variably timed internal combustion engine valve actuation system (10) and method for opening valves in internal combustion engines. The system functions during both positive power and engine braking, to control the amount of 'lost motion' between a valve (160) and a means for opening the valve (150). In particular, the invention relates to a lost motion engine valve actuation system (10) using dedicated cam (100) for effecting exhaust valve (160) openings for compression release braking and exhaust gas recirculation (EGR).
