PURPOSE: To repeatedly burn combustible gas as residual gas and improve fuel consumption efficiency by conically forming a head top of a piston, rounding a top, conically forming a cylinder head on the side of a combustion chamber, and arranging exhaust valves outside a center fuel combustion valve such that valve bars are parallelly arranged to a cylinder shaft.
CONSTITUTION: Reduction 15 in diameter is performed on a head of a piston 2, while a head top is conically formed and a top is formed to be a circle 16. A cylinder head 7 is conically formed on the side of a combustion chamber 6, while a fuel injection valve 10 is arranged on its center. Four exhaust valves 8 are arranged outside the fuel injection valve 10, while a stroke cylinder shaft and valve bars 14 are arranged in a substantially parallel manner. Lean air-fuel mixture is burned perfectly with high speed by strong combustion heat on an outer periphery sequentially. The high temperature perfectly burned gas collected around a center of the combustion chamber 6 by centripetal force is sequentially and selectively exhausted. It is thus possible to repeatedly burn the combustible gas as residual gas, and improve fuel consumption efficiency.
