Summary:PROBLEM TO BE SOLVED: To drop the cooling loss and drop the internal EGR gas amount for use as the thermal energy necessary for compression self-ignition combustion. SOLUTION: The internal EGR gas remaining in a combustion chamber 4 due to minus overlapping of a suction 6 and an exhaust valve 8 is distributed in the central part of the chamber 4 by a swirling stream of fresh air, and around it, the fresh air is distributed and stratified, which allows the internal EGR gas to remain at a high temperature, and thereby the amount of internal EGR gas necessary for compression self-ignition combustion can be reduced to result is heightening of the thermal efficiency, and it is possible to reduce the cooling loss while the fresh air layer distributed in the peripheral zone of the combustion chamber 4 serves as a heat shutoff layer.
