In this paper, the engine optimal matching is done to improve the efficiency of a turbocharged lean-burn LPG engine by optimizing the compression ratio and the distribution phase of camshaft. In this way, the gas consumption and emissions of the LPG engine are reduced. A one-dimensional engine model and a three-dimensional in-cylinder combustion model are set up with simulation software. The optimal compression ratio is determined by comparing the results from simulation and experiment at different compression ratios. The exhaust advance angle and valve overlap angle are optimized on the basis of successive optimization method and demonstrated in experiments.
