Abstract
In this paper, the working process mathematical models of in-cylinder of the diesel engine, exhaust turbocharger and intercooler are established, as well as the simulating model using simulation Software GT-POWER. Through parameters modification, we built the Map of efficiency characteristic curve of compressor and turbocharger. Targeted at the turbocharged intercooled diesel engine of YC4F92 type, simulating calculation and experimental verification are conducted. It turned out that the simulating value and experimental value matches well and the maximum error value is not more than 5%, which demonstrated the accuracy and reliability of the established model. The established model can works as a tool for the design and optimization of diesel engine.
