由电子控制的蓄压式燃油系统,是一种很有前途的燃油系统,它可以将曲轴的最低转速压得很低,还可以降低燃油消耗率和提高柴油机寿命。但是在台架试验中发现这种燃油系统在小循环供油区的稳定性很差,然而通过降低蓄压器内的压力和减小喷孔的有效通流截面,可以使小供油区的循环供油量的不稳定性得到很大的改善,尤其是减小喷孔的有效通流 An electronically controlled accumulator fuel system is a promising fuel system that lowers the minimum crankshaft rpm and reduces fuel consumption and increases diesel engine life. However, this bench test found that this fuel system has poor stability in small-cycle fueling zones. However, by reducing the pressure in the accumulator and reducing the effective flow cross-section of the injection holes, The instability of the circulating fuel supply is greatly improved, especially for reducing the effective flow of the injection hole
