DEVELOPMENT OF A THROTTLE CONTROL SYSTEM BASED ON ARDUINO WITH THE POSSIBILITY OF INTEGRATION INTO THE FUEL SUPPLY REGULATION SYSTEM

Abstract

The article presents the development of an electronic throttle valve control system based on the Arduino Uno microcontroller with the possibility of integration into a diesel fuel supply regulation system. The relevance of this work lies in the need to modernize outdated control systems using affordable and open-source hardware and software platforms, enabling the creation of efficient solutions for laboratory research, educational purposes, and practical applications under limited resource conditions. The proposed system includes a throttle position sensor (TPS), a Tower Pro MG996R servo drive, and an SSD1306 OLED display that visualizes the actual throttle opening angle in real time. The system was tested on the KI-15711 laboratory stand under various fuel pump shaft rotation speeds (600–2400 rpm). A series of experiments were conducted to measure fuel consumption, concentrations of harmful emissions (CO, NO₂),assess throttle position stability, and analyze deviations. The results demonstrate a reduction in average fuel consumption by 6–8%, a decrease in mechanical wear by 10–12%, and a reduction in CO and NO₂ emissions by 7–9% compared to traditional mechanical systems. High linearity and control accuracy were confirmed: the deviation of the throttle opening angle did not exceed ±2°. Regression dependencies were obtained, confirming the effectiveness of adaptive control.
Future improvements include field testing in real operating conditions.
