介绍了快速混合燃烧过程采用较小柱塞直径、较大行程的НТД４０ 喷油泵，提高进气涡流转速和排气道流通系数，配合喷油提前角及进气压力参数的合理匹配，初步实现了高热效率、低爆压和低粗暴度的性能指标。通过 Ａ Ｖ Ｌ６５７ 数字采集分析系统的测量，分析了改进后的燃烧系统。喷油提前角和进气压力的合理匹配降低了爆压；较小柱塞喷油泵的采用，减小了速燃期的放热速度，从而获得较小的工作粗暴度；提高涡流转速保证了快速混合燃烧过程的实现，从而获得高的热效率。
This paper introduces НТД40 injection pump with smaller plunger diameter and larger stroke in rapid mixing combustion process to improve the speed of intake vortex and the circulation coefficient of exhaust passage. According to the reasonable matching of fuel injection advance angle and intake pressure, Achieved high thermal efficiency, low explosion pressure and low roughness of the performance indicators. Through the measurement of A V L657 digital acquisition and analysis system, the improved combustion system was analyzed. A reasonable matching of injection advance angle and intake pressure reduces the burst pressure; the use of a smaller plunger injection pump reduces the rate of heat release during the fast-burning period, resulting in less job crumbs; increasing the vortex flow rate ensures Rapid mixing of combustion process to achieve high thermal efficiency.
