Abstract

PURPOSE: To quicken combustion for less noxious exhaust contaminent resulting by forming a protrusion on the head of a piston, which moves into a semi-spherical hollow space of a cylinder head.
CONSTITUTION: At TDC of a piston 3, a protrusion 12 on the head of the piston 3 moves into a hollow space of a combustion chamber 6 included in a cylinder head 4, where a suction and an exhaust vaive 7, 9 are assembled. When the protrusion 12 comes into the space, the primary and the secondary combustion chamber 6a, 6b appear on the upper and the lower side of it. The primary chamber 6a is made in the semi-spherical form and the external part of the cylinder head 4 into which the protrusion 12 goes is made in the cylindrical form 4c. In a compression stroke, compressed mixture gas from the secondary chamber 6b is squeezed into the semi-spherical primary chamber 6a from the cylinder-shaped space 4c as turbulance and can be burnt quickly in the primary chamber 6.
