The present invention is applicable to various oil and gas internal combustion engine, and is characterized by that the undersurface of the cylinder cap of said engine has recessed pit, and the top portion of piston has projection, and when the piston is uwpards moved and approached to the upper top point, the 'combustion chamber' of middle portion of volume in the cylinder and 'squish gap' of rim are separated, the combustion can be made respectively and successively in said two places, and its time is short, so that it does not produce 'explosion', its compression ratio can be raised to 18-24, and the heat efficiency can be raised by 25-30%. 本发明适用于各种油、气内燃机。此机缸盖下有凹窝，活塞顶部有凸台，活塞上行接近上顶点时，缸内容积中部的"燃烧室"与沿边的"挤气间隙"分开，燃烧先后分别在此二处进行。时间都短，所以不会发生"爆燃"。由于没有爆燃，压缩比可提高到18～24，热效率可以高25～30％。
