【 摘 要 】

The fuel injection pulse of the electronically controlled injection gasoline engine is fully solidified in the ECU. In addition, the engine injection control uses negative feedback control. It is difficult to control the injection quantity of the engine without an external electronically controlled development system.Therefore, universities that do not have the ability to develop electronically controlled ECU have stopped or canceled gasoline fuel adjustment characteristics tests. In view of the current problem, based on the STM32 library function, this study developed an experimental device, which can docking well with the engine in use, and can easily input the injection pulse width without changing the original ECU of the engine, thereby controlling the mixture concentration of the engine and completing the fuel adjustment characteristic experiment easily. The fuel adjustment characteristics experiment was completed on the engine test bench, which verified that the developed experimental device has good practicality.
