Abstract :
In this paper, the engine optimal matching is done to improve the efficiency of supercharging lean burn LPG engines by optimizing the compression ratio and the distribution phase of camshaft. The gas consumption and emissions of LPG engine are reduced. A whole engine model is set up on one-dimensional simulation software. The optimal compression ratio is determined by comparing the simulation computed results and bench experimental results under different compression ratios. The exhaust advance angle and valve overlap angle are optimized on the basis of successive optimization method and demonstrated in experiments.
