IPC: F02B23/08
Filed: 1986-10-03
Abstract: PURPOSE:To aim at enhancing the efficiency of combustion, by forming, in the top part of a piston, a recess opened toward the lower surface of a cylinder head, by reducing the opening area of the opening of the recess with respect to the inside of the recess and by arranging a spark plug so that it confronts the inside of the recess. CONSTITUTION:A recess 5 opened toward the lower surface of a cylinder head 4 is formed in the center part of the upper section of a vent-roof type piston 1. This recess 5 has such a shape that the opening area of its opening 5a is reduced with respect to the inside of the recess 5. A spark plug 8 is mounted in the lower surface of the cylinder head 4 so that spark plug 8 is projected into the recess 5 in the vicinity of the top dead center of the piston 1, and the sparking section 8a of a spark plug 8 enters completely into the recess 5 when the piston 1 is at the top dead center. Further, the inner surface part of the recess 5 is formed of a relatively thin ceramic layer 9 which insulates heat only against the inside of the recess 5, thereby it is possible to prevent the engine from being out of order due to knocking or the like and while cooling loss is prevented from increasing.
