ABSTRACT:
An internal combustion engine of lean air-fuel mixture combustion type comprising a subsidiary combustion chamber opening into a main combustion chamber via a connecting passage. A raised portion is formed on the top surface of the piston. The raised portion extends from the peripheral end of the inner surface of the cylinder head to the vicinity of the opening of the subsidiary combustion chamber for creating a squish flow along the inner surface of the cylinder head. The connecting passage is arranged so that a high velocity burning jet injected from the subsidiary combustion chamber meets with the squish flow at an angle of less 90.degree..
