| 摘 要： | 基于液态LPG／柴油混合燃料在油泵前按一定比例混合和缸内直喷压燃的构想，开发了液态LPG／柴油比例混合电子控制系统。对该控制系统进行的一系列性能测试结果表明，它能根据发动机不同工况的需要，任意调节液态LPG／柴油的混合比，且调整精度较高。应用该系统，进行了直喷式LPC／柴油混合燃料压燃发动机的性能试验。试验结果表明：直喷式LPG／柴油混合燃料压燃发动机具有与柴油机相同的动力性与燃料经济性，而其烟度、NOx和HC排放均优于原柴油机。

| Abstract: | For operation of LPG/diesel fuel blends on direct injection compression ignition engine, an electronic control system is developed to make wide range adjustment of LPG/diesel ratio according to engine operating conditions. Performance experiments were undertaken and the result showed that the control of LPG/diesel ratio is feasible and the system can accurately supply fuel blends to the engine. Experimental results also showed that the performance and exhaust emission characteristics of the engine operated with LPG/diesel fuel blend are superior to those of the original diesel engine. |
