摘　　要：基于一台中置喷油器的单缸直喷汽油机,分别进行中、高滚流气道条件下多次点火和单次点火的发动机试验,研究多次点火和单次点火对发动机性能的影响.试验表明:中滚流气道中等负荷2000 rpm@5.8 bar工况下,燃油经济性有改善,CO排放有一定降幅,HC排放没有明显改善;高滚流气道2000 rpm@2.8 bar工况下,油耗有一定降幅,HC和CO排放均下降.Based on a single cylinder direct injection gasoline engine with a middle injector,multiple ignition and single ignition tests were carried out under medium and high rolling air passage conditions.The effects of multiple ignition and single ignition on engine performance were studied.The test results show that the fuel economy is improved,CO emissions are reduced to a certain extent,and HC emissions are not significantly improved under the medium load of 2000 rpm@5.8 bar.Under the condition of 2000 rpm@2.8 bar of high rolling air passage,fuel consumption decreases to a certain extent,and HC and CO emissions decrease.
