ABSTRACT:
An air control valve (20, 21) is coupled to the minimum volume region of each cylinder (11, 12) in an internal combustion engine. The open interval of the valves during each engine cycle is controlled responsive to the throttle (FIG. 2) to equalize the air-fuel ratio. The clearance of the pistons is also adjusted responsive to the throttle (FIGS. 3A and 4A) to equalize the compression pressure during engine operation. Specifically, in an engine with two cylinders each having opposing pistons, the coupling systems between the piston rods and the crankshaft exhibit diagonal symmetry (FIG. 1).
