Research on the Characteristic Description and the Numerical Model of 4G15-6L Automotive Engine

This article mainly discussed the establishing process of the 4G15-6L automotive engine simulation model. The numerical model was set up for the engine using engine’s experimental data. Therefore the engine’s optimal economic and dynamic curves were drawn. According to the established mathematical model, the simulation experiment model can be built by Matlab or Simulink. The feasibility and reliability of the model were verified through the test, and the model met the requirements of hardware in loop simulation. Meanwhile, the model built the foundation of the engine’s simulation platform in the next step.
