In the design stage of electronic controlled diesel engine control system, to establish its simulation engine model and carry on HILS is a very important step. This paper introduces a new simulation method based on Matlab/RTW and VxWorks real-time operating system. The engine model constructed by Simulink can produce the embedded real-time 6ode optimized automatically, and adjust the model parameter and monitor the simulation data online. Compared with traditional method to write and revise the simulation model code by hand, the method has accelerated the research of the hardware in the loop simulation. Through the analysis of the simulation result of the 6110/125zl diesel engine, the fast feasibility of this method has verified.
