FOUR-CYCLE INTERNAL COMBUSTION ENGINE

摘要

A four-cycle internal combustion engine, particularly with externally controlled ignition, in which the piston is provided with an essentially cylindrical piston combustion space and in which a swirl of the charge present in the combustion space is produced by suitable squeeze flow channels terminating substantially tangentially in the piston combustion space within the area of the compression top dead center position of the working piston; the squeeze flow channels are formed by a suitable design of the working piston and/or of the cylinder head.
