Abstract
Disclosed is an internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. Fuel is fed into the accumulation chamber to form therein a rich mixture. In the first half of the compression stroke, a jet of the rich mixture is spouted out into the combustion chamber from the accumulation chamber to stratify the inside of the combustion chamber so that the rich mixture is collected around the spark plug. In the latter half of the compression stroke, a lean mixture in the combustion chamber flows into the accumulation chamber to accumulate the mixture under high pressure, which is spouted out into the combustion chamber at the next cycle, in the accumulation chamber.
