Abstract

PURPOSE: To quicken combustion and improve the efficiency of combustion with less noxious exhaust contaminent resulting by forming a protrusion on the head of a piston, which comes into the hollow space of a cylinder head.
CONSTITUTION: At TDC of a piston, a protrusion 12 made on the head of a piston 3 moves into a hollow space of a combustion chamber 6 involved in a cylinder head 4, where a suction and an exhaust valve 7, 9 and an ignition plug 11 are assembled. At TDC of the piston, the primary and the secondary combustion chamber 6a, 6b appear on the upper and the lower side of the protrusion 12 and a clearance P between 2 and 4mm are made around the protrusion 12. Mixture gas in the secondary chamber 6b is squeezed into the primary chamber 6a as fast as ignition spark in the primary chamber 6a cannot be extinguished. Combustion is, therefore, provided effectively in the primary chamber 6a
