Abstract
An internal combustion engine is provided that basically comprises a cylinder block, a cylinder head, a piston, an auxiliary chamber partition wall and a spark plug. The auxiliary chamber partition wall is coupled to the cylinder head and extending toward the main chamber to form an auxiliary combustion chamber inside an area enclosed by the auxiliary chamber partition wall. The auxiliary chamber partition wall has at least one jet aperture through which the auxiliary combustion chamber fluidly communicates with the main combustion chamber. A tip portion of the auxiliary chamber partition wall that faces toward the piston has a smaller wall thickness than other portion of the auxiliary chamber partition wall.
