车用汽油总体是由碳氢化合物(HC)组成的,衡量汽油的主要性能指标有抗爆性、蒸发性、热值和氧化稳定性、清洁性与胶质成分。提高汽油的抗爆性(辛烷值)主要依靠各种烃类化合物化学组分的调和配比来保证的。然而,汽油中的芳烃和稀烃,虽然能提高汽油的辛烷值,但会在燃烧后产生沉积物胶质和积炭,涂覆在进气道、燃烧室表面和喷油器头上,造成表面炽热点火,并破坏喷油器的雾化质量和喷油流量。使发动机动力下降、油耗增加。而汽油中的硫燃烧后,以带有
Automotive gasoline is generally composed of hydrocarbons (HC), the main performance indicators measured gasoline antiknock, evaporation, calorific value and oxidation stability, cleanliness and glial composition. Improving the antiknock (octane number) of gasoline depends mainly on the blending ratio of the chemical components of the various hydrocarbon compounds. However, aromatics and hydrocarbons in gasoline, while increasing the octane rating of gasoline, can produce deposits of colloidal and carbon deposits upon combustion, coating the intake port, the surface of the combustion chamber, and the injector head, Resulting in a hot surface ignition, and destroy the atomizer spray quality and fuel injection flow. The engine power down, fuel consumption increased. The sulfur in gasoline after burning with
