ABSTRACT:
An internal combustion gasoline engine for reducing undesirable exhaust emissions, hydrocarbons, carbon monoxide and nitrogen oxides mainly by means of the design techniques for exhaust passages. The present engine comprises two determined regions extending from an exhaust valve downwards in the exhaust passage so as to pass exhaust gases therethrough in their discharging order, one region having a volume permitting self-reaction of unburned constituents of exhaust gases therein at a temperature of the exhaust gases and another having so much volume and sectional area as capable of aspirating air by itself (automatically) through a check valve into the exhaust passage.
