Analysis and Implementation of Key Technologies in Turbocharging Simulation System Design

This paper studies and develops a system for matching modern internal combustion engines with turbochargers. The preliminary design of turbocharging system is performed according to the type of turbocharging system of target engine when the basic parameters and environmental parameters of the target engine are determined. Then, through specific analysis and calculation, the matching process between turbocharger and engine is analyzed, and the calculation method and matching process of selecting turbocharger with known engine basic parameters are summarized, as well as the setting criteria of each parameter during engine turbocharging. A series of formulas and equations are deduced based on experiments and previous results, and the design methods of compressor shell and turbine box channel are determined. Finally, the structure of the simulation program is designed. The system is used for modeling and analysis, and the simulation results are compared with the experimental results to verify the correctness of the simulation data.
