| Abstract: | In this paper, AVL-BOOST software was used to make a calculation model of a 4C28 automobile diesel engine with electronic controlled VE pump. With the purpose of optimizing the performance and meeting China- HI emission standard, this paper studied the effects of compression ratio, advanced angle of injection and valve timing on the performance of the diesel engine. It simulated the Nox emission of the optimized diesel engine, and found that the Nox emission level met the China-Ⅲ emission standard. It simulated the performance on the external characteristics curve, and put a comparison with the test one. Its proved that the simulating result is correct, and the emission of the specimen machine can meet the China- Ⅲ emission standard. |
