Effect of Enhanced Mixture Formation on the Combustion Characteristics in Gasoline Engine
가솔린 기관의 혼합기 형성 촉진이 연소 특성에 미치는 영향
Abstract
In this paper, the fuel atomization effect of a spark-ignition engine on the lean burn characteristics is studied. The fuel atomization is enhanced by heating the inside of the intake manifold with electric heater. Several operating parameters including cyclic variation are expressed against the air-fuel ratio from the experimental results. The fuel atomization gives much influence on the combustion stability. As the intake manifold is heated, the combustion duration decreased and the value of COV in the lean region as well as in the theoretical equivalence ratio became smaller than of not-heated.
