摘　　要：针对国内市场特点开发了一种新型柴油机电控燃油喷射系统——电控组合泵,该系统在工作原理上与电控单体泵相同,外形尺寸和机械接口与传统的直列泵相似。台架试验显示,该系统具有较高的喷射压力和优良的喷射规律,对喷油定时和喷油量可实现灵活且精确的控制。与多款柴油机的匹配试验结果表明,该系统是一种满足国III排放法规的理想解决方案。A new diesel electronic fuel injection system——electronic compound pump is developed for Chinese market. This system is same to electronic unit pump regarding working principle, and similar with the mechanical in-line pump in term of the geometric size and the mechanical connection. It is shown that this system can provide high injection pressure, excellent injection profile, flexible and precise control of injection timing and injection quantity. The test results on engines indicate that this system is an ideal solution to meet the national III emission legislation.
