Modeling and Simulation of Crush Natural Gas Turbo Engine

The development of Crush Natural Gas (CNG) Engine Control Unit (ECU) depends on expensive bench tests or traditional gasoline engine simulation software, which expand researching and developing period. A new approach is presented in this paper, in which a novelty CNG Turbo engine model based on Mean Value Model and Hardware In Loop (HIL) platform are included. The model acts as many roles e.g. simulation, embedded fault diagnosis and ECU test model which provide more accuracy and efficiency for development of ECU. The new HIL simulation policy is based on Matlab/Simulink, Real Time Workshop (RTW) and NI PXI board. The experiment results prove that it acquired quality Real-time response and accuracy, and economy budget.
