有机醇对汽油发动机尾气CH化合物有一定的减少,讨论了燃油的表面张力与温度.尾气CH化合物浓度.燃油的雾化效率的关系.并提出了醇降低汽油发动机尾气CH化合物的机理——表面张力理论:醇作为一种表面活化剂,可以使燃油的表面张力下降,使燃油雾化效果好.扩散速度快.与空气混合充分,提高了燃烧温度,降低了发动机激冷层.从而减少了CH化合物排放量.
The organic alcohols have a certain reduction in gasoline CH, and the relationship between the surface tension and the temperature of the fuel, the concentration of CH compound in the exhaust gas, the atomization efficiency of the fuel, and the mechanism that the alcohol reduces the CH compound of the gasoline engine exhaust, Tension theory: alcohol as a surfactant, can reduce the surface tension of the fuel, so that the fuel atomization effect is good. Diffuse speed. Mix fully with air to improve the combustion temperature, reducing the engine chilling layer. Thus reducing the CH Compound emissions.
