【Abstract】 The model of a turbocharged diesel engine is built using GT-power software. According to the experimental data,the accuracy of the model is verified. By simulation of the turbocharged diesel engine, the variation of performance parameters under different compression ratios and valve timings is analyzed, and the compression ratio and valve timing are optimized. The results can provide theoretic guidance for this turbocharged diesel engine.更多还原
