Abstract

PURPOSE: To improve the efficiency of combustion with less noxious comtaminent resulting by forming a protrusion on the head of a piston and a circle channel curved on the round wall of it, in which unburnt HC is temporally held.
CONSTITUTION: A protrusion 12 is made on the head of a piston 3 and when the piston 3 nears TDC, goes into a hollow combustion chamber 6 which is included in a cylinder head 4 and involves the suction and exhaust vlave 7, 9 and an ignition plug 11. And a circle channel 13 is made on the round wall of the protrusion 12. 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. In compression stroke, mixture gas in the secondary chamber 6b is squished into the primary chamber 6a for rising in combustion speed. Heat is removed from unburnt HC kept in the channel 13 to derease combustion tmperature goes down due to internal EGR effect so that NOx is limited to create
