基于电控单体泵的性能匹配试验研究

针对某电控单体泵燃油系统在某单缸机高转速试验过程中出现的工作稳定性差、油耗高等问题,对该单体泵、高速凸轮与电控系统,在喷油泵试验台上进行进一步高转速下的性能匹配试验,确定该电控单体泵在单缸试验过程中出现问题的原因,适用的高转速范围、及解决问题的方法,为单缸机下一步的性能匹配试验提供支持.

Experimental Study on Performance Match of Electric Unit Pump

For solving the problems of bad stability and high fuel consumption during single-cylinder engine high speed test,the performance match was tested at high speed on fuel injection pump test bench between unit pump,high speed camshaft and electric control system,to confirm the cause of problems during single-cylinder engine test,the applicable range of high speed and the approach to solve those problems.Finally the next performance match test method of single-cylinder engine is presented in this paper.
