摘　　要：为了实现非道路柴油机的欧ⅢA排放,研制开发出P4HE00电控组合式单体泵燃油喷射系统。该系统具有较高的喷射压力和较好的喷射特性,可灵活调节且精确控制喷油定时和喷油量。配机试验结果表明,该系统获得了良好的低排放效果,达到了非道路欧ⅢA排放标准的要求。In order to make off-road diesel engine meet Euro ⅢA emission standards,electronic compound unit pump fuel injection system is developed.This system can provide high injection pressure,excellent injection profile,flexible and precise control of injection timing and injection quantity.The test results on engine show the system has good emission control effects and can meet the off-road Euro ⅢA emission level.
