【Abstract】 This paper describes the experimental results of improving the performance of small two stroke gasoline engine by means of stratified charges and exhaust gas dynamic effect. The lowest specific fuel consumption is 315 g/kw·h. As the engine load varies, the requlation of the inlet charge becomes qualitatively. So that at partial load the dynamic characteristics of the engine is improved greatly. when the engine runs at medium and high speeds, the harmful exhaust gases CO and HC are reduced in quantity. The engines with stratified charges will keep the advantages of simple constrnction and wide application.更多还原
