Enhancing Development Efficiency of Engine Electronic Control Systems

To enhance the development efficiency and reduce costs of engine electronic control systems, we constructed a computer simulation model for gasoline engines using MATLAB/Simulink tools based on fundamental engine working principles. The implementation involved creating subsystem blocks for combustion modeling, intake dynamics, and sensor emulation, with Simulink's graphical programming interface enabling real-time parameter adjustments. Through necessary validation procedures including step response tests and frequency domain analysis, we demonstrated the model's capability to accurately reflect throttle opening variations and load changes. Furthermore, we conducted additional research exploring the impact of other variables on engine performance, such as fuel injection timing and ignition advance angle. These investigations incorporated control algorithm simulations using Stateflow for finite-state machine logic and PID controller tuning via Optimization Toolbox. The studies provide deeper insights into engine behavior and offer enhanced references for optimizing electronic control system design through data-driven calibration approaches.
