Abstract
PURPOSE: To improve combustion of an engine, by forming a notch groove permitting a compression chamber to communicate with a combustion chamber.
CONSTITUTION: Along a circumferential edge 2a of a cylinder head 2 facing to a combustion chamber 4, there is provided an annular groove 11 which is opened toward a piston 3. A notch groove 13 is formed toward a plug gap 10 in an annular protrusion 12, while an annular protrusion 14 is formed toward the groove 11 along a circumferential edge 3a of the piston 3. When the piston 3 is moved near a top dead centre at the compression stroke, the annular protrusion 14 advances in the groove 11 to form a compression chamber 15, when the mixture in the compression chamber 15 is injected under a compressed state to the plug gap 10 from the notch groove 13 as the piston 3 rises up, scavenging the plug gap 10 and producing swirls in the combustion chamber 4.
