ABSTRACT:
An internal combustion engine according to the present invention includes a piston reciprocally movable within a cylinder for affording rotational motions to a crankshaft, a combustion chamber formed among the piston, the cylinder and a cylinder head, an intake valve mechanism for opening and closing an intake passage to be communicated with the combustion chamber, igniting means having its igniting portion facing the combustion chamber, fuel supply means for supplying a predetermined quantity of fuel toward a predetermined wall of the combustion chamber, which is heated to a predetermined high temperature by the combustion in the combustion chamber, and an exhaust valve mechanism for opening and closing an exhaust passage to be communicated with the combustion chamber. During the running operation, the fuel is brought by the fuel supply means into contact with the predetermined wall having the predetermined high temperature of the combustion chamber, which is evaporated from the surface of the wall, so that the gasification of the fuel is promoted to effect combustion with high efficiency and to prevent emission of unburned noxious contents such as hydrocarbons.
