电喷汽油机燃用丁醇-汽油混合燃料的循环变动特性
|
摘要
对某电控进气道多点喷射汽油机分别燃用国Ⅳ汽油、纯丁醇,以及丁醇体积比分别为10%、15%、20%、50%、85%的汽油-丁醇混合燃料的循环变动特性进行了试验研究,试验中未对发动机进行任何改动。研究结果表明:与汽油的燃料特性相比,随着丁醇-汽油混合燃料中丁醇含量的升高,汽油机燃用丁醇-汽油混合燃料的缸内压力峰值及其对应曲轴转角的循环变动率、压力升高率峰值循环变动率及放热率峰值及其对应曲轴转角的循环变动率增大。
In a multi-point EFI gasoline engine,cyclical fluctuation characteristics was studied while it fueled with conventional gasoline,pure butanol,10%,15%,20%,50%,and 85%(in volume)butanolgasoline blends respectively.The gasoline engine was not any modified.Test results show that compared with pure gasoline,with butanol content in blends increasing,the fluctuation rates of in-cylinder pressure peaks and their corresponding crank angles,pressure rise rate peaks and heat release rate peaks and their corresponding crank angles increased when the engine fueled with the blends.
