In an engine having at least one cylinder with a reciprocating piston and a connecting rod for driving rotation of a crank disk and a crankshaft, a cam sleeve is moved along the crankshaft in response to a change in engine speed. The cam sleeve is coupled to a cam ring that moves with the cam sleeve and in a spiraling motion about the longitudinal axis of the crankshaft. A follower engages an outer face of the cam ring and is movable against a push rod that opens an injector valve. The follower is structured and disposed to move in response to contact with a lobe on the outer face of the cam ring to urge the push rod against the injector valve. The follower changes position on the cam ring as the cam ring is moved in the spiraling motion, causing the follower to be exposed to a progressive change in profile of the lobe, resulting in a varying degree of movement of the follower to thereby control timing and duration of momentary opening of the injector valve and injection of pressurized steam into the cylinder.
