Combustion chamber of an internal combustion engine

摘要

Disclosed is an internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via a valve. The opening operation of the valve is controlled so that the valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle, in the accumulation chamber.
