PURPOSE:To simplify the structure and to improve the reliability by connecting the delivery port of a fuel mixing means through a fuel path arranged with a check valve and a thin hole made at a portion of a cylinder liner to a combustion chamber. CONSTITUTION:A thin hole 7 opening toward the flow of an intake air flowing through an intake port 5 made in a cylinder head 4 into a combustion chamber 6 is made at a flange section 3 located at the upper end of a cylinder liner 2. Then the delivery port of the fuel mixing means 8 and the thin hole 7 are connected through a fuel path 9 while a check valve 10 is arranged in the fuel path 9. The fuel delivered from the fuel mixing means 8 is fed through the check valve 10 and the thin hole 7 into the combustion chamber 6 directly. Consequently, the fuel does not adhere to the wall face of the intake port 5 thereby the deterioration of fuel consumption and the increase of the concentration of HC, CO are prevented while the enclosing performance of the combustion chamber 6 is ensured by the check valve 10 and the application of high voltage onto the fuel mixing means 8 is prevented.
