一、前言TX375Q－1型柴油机是机械工业部洛阳拖拉机研究所与浙江新昌内燃机厂共同研制开发的小型高速直喷式柴油机。该机原设计配用三缸互号喷油泵。该茶在配试过程中，出现了扭矩特性严重超出的现象。在柴油机最大扭矩转速下，扭矩储备高达30％～40％。使发动机最大扭矩工况燃 I. Introduction TX375Q-1 diesel engine is a small high-speed direct-injection diesel engine jointly developed by Luoyang Tractor Research Institute of Ministry of Machinery Industry and Xinchang Internal Combustion Engine Factory of Zhejiang Province. The aircraft was originally designed with three tanks each other fuel injection pump. The tea in the test process, there has been a serious distortion of the phenomenon of torque. Under the maximum torque of diesel engine, the torque reserve is up to 30% ~ 40%. Make the maximum torque of the engine burn
