电喷汽油机循环变动的测量分析
The Measurement and Analysis of Cyclic Variability on an Electronically Injection Gasoline Engine
【摘要】 本文在EQ491汽油机上测取了电喷改装前后的示功图,经过对比分析认为:随负荷及转速增加,燃烧循环变动降低;在空燃比一致时,电喷汽油机与化油器式汽油机的燃烧循环变动一致。论文还对在怠速工况燃烧循环变动进行了统计分析。
【Abstract】 This paper measured the indicator diagrams on an EQ491 gasoline engine both equipped electronically injection system and carburetor.The results show that the combustion cyclic variability is decreasing with the load and speed increasing,and under the same air-fuel ratio, the cyclic variability of gasoline injection engine is similar to that of the gasoline carburetor engine.This paper also discussed the combustion cyclic variability at idle condition.
