Abstract

PURPOSE: To quicken combustion and improve the efficiency of combustion by forming a protrusion on the head of a piston, which comes into the hollow space of a cylinder head.
CONSTITUTION: A protrusion 12 which moves into a hollow combustion chamber 6 at TDC of a piston, existing in a cylinder head 4 and having a suction and an exhaust valve 7, 9 and an ignition plug 11, is made on the head of the piston 3. At TDC of the piston, the primary and the secondary chamber 6a, 6b appear on the upper and the lower side of the protrusion 12 and a clearance P between 2 and 4mm is made around the protrusion 12. At TDC of the piston, the secondary chamber 6b is to be a squish area with samll capacity. In a compression stroke, compressed mixture gas in the secondary chamber 6b is squished into the primary chamber 6a and can be properly burnt in the primary chamber 6a
