A quasi-dimensional mathematical model for direct injection turbocharged diesel engine was established and a set of software was developed to simulate and predict diesel engine performance and emissions. The simulation calculation and optimization analysis of the working process and combustion performance of diesel engine were carried out. The application of Type 1 35 turbocharged diesel engine shows that the software has such advantages as high prediction accuracy, optimized parameter selection and convenient operation.
