OPTIMIZATION OF THE EMBEDDED SOFTWARE OF THE POWER PLANT CONTROL SYSTEM FOR WHEELED VEHICLES

Background

Improving the fuel economy of a power plant remains a popular research topic for any wheeled vehicle, be it agricultural machinery or commercial vehicles, as it directly affects the economic efficiency of the relevant enterprises.

Aims

Improving the fuel economy of an atmospheric gasoline internal combustion engine by fine-tuning the valve timing.

Methods

This research paper proposes methods for reducing fuel consumption in atmospheric internal combustion engines by optimizing the software of the valve timing control system with variable opening phase of the intake and exhaust valves without loss of vehicle dynamics.

Results

As a result of the conducted full-scale experiment, a decrease in gasoline consumption of a passenger car in urban operating conditions of more than 10% was recorded while maintaining the vehicle dynamics.

Conclusions

The research work was aimed only at fine-tuning the variable valve timing control system and did not affect the adjustment of other complex ICE systems, although optimization of the timing system provides even greater potential for obtaining noticeable improvements in engine performance with complex optimal tuning of the fuel supply system, ignition timing angle and torque model.
