Abstract
A compression ignition internal combustion engine having a swirl chamber and a primary combustion chamber both of which are fluid-connected by a primary communicating passage has a recess portion at the fuel impinged portion of the swirl chamber for producing a plurality of small swirls. A pair of second communicating passages connecting the swirl chamber and the primary combustion chamber are so designed as to be directed to the center of the swirl chamber whereby the separation of fuel and air is prevented and the harmful components within the exhaust gas are effectively reduced without deteriorating the combustibility of the mixture.
