ABSTRACT:
An internal combustion engine comprising a subsidiary combustion chamber connected to a main combustion chamber via a connecting passage. The subsidiary combustion chamber is divided into a first chamber and a second chamber by an annular raised portion formed on the subsidiary combustion chamber. The connecting passage communicates the main combustion chamber with the first chamber for leading a combustible mixture from the main combustion chamber into the first chamber and is arranged so as to create a swirl motion of the combustible mixture in the first and the second chambers. When the combustible mixture is ignited, the annular raised portion serves to prevent outflow of an unburned mixture from the second chamber to the first chamber.
