Based on a 3-cylinder 1.5L dedicated hybrid engine, the influence of three different ignition modes, using single spark plug, passive pre-chamber and triple spark plugs, on the engine combustion and emission characteristics was studied under lean-burn conditions. The test results at the speed of 2000r/min and the brake mean effective pressure of 0.8MPa show that under high-tumble intensity, the lean limit with passive pre-chamber ignition corresponded to an excess air ratio ϕa of approximately 1.70, which is slightly lower than that of single spark plug. In contrast, triple spark plug ignition can maintain stable combustion with a ϕa greater than 1.95, thereby improving the fuel consumption and raw NOx emissions. As the air dilution increases, the advantage of passive pre-chamber ignition in improving combustion phasing gradually weakens, while the corresponding ignition delay and combustion duration increase more obviously. Triple spark plug ignition can effectively accelerate the combustion rate, and this advantage becomes more significant especially when ϕa exceeds 1.70, the combustion duration could be shortened by nearly 4°CA compared to those of single spark plug and pre-chamber. When using triple spark plug ignition and a lean mixture with ϕa of 1.80, the engine achieved a highest brake thermal efficiency(BTE) of 45.06% with the fuel of 92 research octane number(RON). With RON100 fuel and further utilization of electronic supercharger, the highest BTE can be increased to 45.63% and 47.04% respectively.

基于一台3缸1.5L混动发动机,研究了单火花塞、被动预燃室及三火花塞3种不同点火方式对发动机稀燃工况下燃烧和排放特性的影响.通过2000r/min转速、0.8MPa平均有效压力下的测试表明:在高滚流下,采用被动预燃室点火能实现的稀燃极限对应过量空气系数ϕa约为1.70,相比单火花塞略低,采用三火花塞点火则可在ϕa>1.95的条件下稳定燃烧,进而改善燃油消耗率和NOx原始排放.随着空气稀释增加,采用被动预燃室点火对燃烧相位的改善效果逐渐减弱,且使得滞燃期和燃烧持续期增加明显.相比之下,三火花塞点火可有效加快燃烧速率,尤其在ϕa>1.70时优势显著,其燃烧持续期相比单火花塞和被动预燃室可缩短近4°CA.通过采用ϕa为1.80的稀混合气配合三火花塞点火,发动机在选用研究法辛烷值(RON)为92的燃油时可实现45.06%的最高有效热效率(BTE),选用RON100燃油及进一步采用电子增压器时,最高BTE可分别提升至45.63%和47.04%.
