Abstract:
1. In an internal combustion engine having at least one power piston that reciprocates within an engine cylinder to define a combustion chamber and which is coupled to an engine crankshaft and having a camshaft which is turned by the crankshaft and having an throttle control which is movable to vary the power output of the engine and a fuel inlet valve having a sleeve and a valve piston which is movable along a path of travel which extends axially within said sleeve to the combustion chamber, the improvement comprising: first means for increasing the volume and thereby reduce the compression ratio of the combustion chamber when the throttle control is moved to increase the power output of the engine; second means for increasing the opening of the inlet valve when the throttle control is moved to increase the power output of the engine; third means for opening the inlet valve earlier and closing the inlet valve later during each inlet stroke of the power piston when the throttle control is moved to increase the power output of the engine; wherein said first means includes first linkage means connecting said throttle control and said valve piston to move said valve piston away from said combustion chamber as said throttle control is moved to increase the power output of the engine; wherein said throttle control includes a rotatable throttle shaft, and said first linkage means includes an eccentric component secured to said throttle shaft and connected to said valve piston.
