The piston has an end and has a flat defined near the end. The actuator has a stem member positioned therein. The stem member has a central portion which is threadedly positioned within the threaded portion of the central bore. The stem member defines a first end and a second end, and a threaded portion is located near the second end. The first end of the stem member and the end of the piston has a predetermined length which is adjustable. The predetermined length is adjusted by threadedly rotating the stem member relative to the piston. A locking device fixes the predetermined length during operation of the engine.
An engine has a cylinder having a piston therein and a pair of valves operatively positioned relative to said piston, said pair of valves each having an end, each of said end being actuated by a valve bridge, said valve bridge moving said pair of valves between an open position and a closed position during an operating mode of said engine, said engine comprising:
