ABSTRACT:
A four-cycle internal combustion engine comprising a cylinder bore formed in a cylinder block, a piston slidably fitted in the cylinder bore, and a combustion chamber formed in a cylinder head above the piston. The bore, piston and combustion chamber have an elongated non-circular cross-section which, for example, can be of elongated circular or elliptical shape. An intake system for fuel mixture is connected to the combustion chamber to supply fuel mixture to a central region of the combustion chamber and an exhaust system is connected to each end of the combustion chamber in an outer region for discharge of exhaust gases.
