Abstract
PURPOSE: To urge vaporization of the fuel and thereby obtain good combustion by forming a fuel film in a great extent through such an arrangement that the combustion chamber is formed spherically and the fuel injection is made in many directions as well as equally apart from the wall of combustion chamber and in the tangential direction to the same.
CONSTITUTION: A cavity 4 having the form of part of a sphere is provided in the middle of the top wall of piston 3, and a fuel injection valve 6 is installed, whose axis shall be identical to the line A formed when the center 0 of the cavity 4 is connected to its opening part C. This fuel injection valve 6 is so designed as to inject the fuel in a conical film from a ring-shaped jet 10A to be formed by a valve element 23 of poppet type and a valve seat 22. The fuel is injected by the injection valve 6 equally apart form the inner wall of the cavity 4 and in the tangential direction to the same, so thas is spreads widely alongside the inner wall to form a film of fuel. Thus the vaporization area can be increased and the vaporization promoted.
