摘要
A genetic algorithm optimization method based on simulation was used to study the valve timing optimization of a certain type of spark⁃ignited aircraft piston engine.By coupling engine performance model and modeFrontier software, the intake and exhaust timing, intake and exhaust duration were optimized to achieve better engine performance.The analysis results showed that the engine power increased by 7.3% and the fuel consumption rate reduced by 2.5% under cruising condition.The optimized intake and exhaust timing can also improve engine performance under 100% throttle opening, which can reduce taxiing distance of the aircraft equipped with the engine.
