ABSTRACT:
A multi-cylinder two-stroke cycle engine according to the invention incorporates a plurality of cylinders (1,2,3) arranged in line with each cylinder having at least two inlet ports one on each of the two opposite longitudinal sides of the in-line cylinders (1,2,3). Air passages (67,77) extend along said opposite sides to supply air from a supercharger (not shown) to the respective inlet ports. An air control valve (68) is operable to selectively control air supply to one or both of said air passages (67,77) whereby optimum combustion conditions are obtained for various engine load/speed conditions. A centrifugal supercharger arrangement is also disclosed, the supercharger being coupled to the engine crankshaft and interposed between the cylinder block and the engine flywheel.
