电喷汽油机使用乙醇汽油的试验研究

Gasohol Experimental Research on EFI Gasoline Engine

在电喷汽油机参数未作任何调整的情况下,试验研究了燃用乙醇汽油对发动机动力性和经济性的影响。研究表明:电喷汽油机改燃乙醇汽油后,全负荷时汽油机动力输出不变;但部分负荷时,动力输出稍微有所下降;与普通汽油相比,乙醇汽油的燃油消耗率有所增加;在怠速工况下,汽油机的CO、HC等废气排放有显著降低。

In the situation of the gasoline-injection engine parameter not to do any adjustment, we do the experimental that the ethyl alcohol gasoline to the engine power and the efficient influence. The research indieated： After the Gasoline-injection engine changes bums the ethyl alcohol gasoline, Full-load gasoline engine power output unchanged, but partial load Gasoline engine power output has declined slightly. Compares with the regular grade gasoline, the ethyl alcohol gasoline＇s fuel oil consumption rate increases： Under the idling regime operating mode, Gasoline engine＇s emission of CO, HC and so on have obviously reduce.
