Блок керування стендом для промивки та тестування паливних форсунок бензинового двигуна на базі мікроконтролера ESP32

Abstract

The paper considers the development of a test bench for cleaning and testing gasoline fuel injectors based on the ESP32 microcontroller. The hardware structure of the system is described, including MOSFET switches for injector control, a TFT display for parameter visualization, and rotary encoders for adjusting frequency, pulse duration, and engine speed. The main operating modes are analyzed: engine simulation, continuous mode, static mode, step test, soft and intensive cleaning, burst mode, and frequency sweep mode. Particular attention is paid to the algorithm for automatic frequency calculation and the nonlinear dependence of pulse duration on engine speed and load. Prospects for expanding the functionality by adding additional diagnostic features are identified.
