The modeling method is commonly used in the simulation of engine at home and abroad, the engine which is used for auto control and performance analysis model. It includes static and dynamic modeling methods, such as engine nonlinear autoregressive model, the average model, the chart model and hybrid model. .In the actual process of modeling, we should make a trade-off between simplicity and accuracy of the model, select the appropriate modeling method for the specific problem.

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.

Using the empirical data as little as possible. based on Matlab/RTW and VxWorks real time operating system.The simulation precision and stringent restriction to the We construct the real time simulation systems include diesel computing time is always pair of contradictory in many engine dynamic model and the NOx emission neural network (NN) . X. t X o s model. This model is set up by Simulink and can be generated to situations There are two kinds of soluion, simplifies the model embedded real time code optimized automatically by RTW. The under the guaranteed certain precision or enhances the model parameters and simulation data can be adjusted online. processor operation ability. Compared with traditional method to write and revise the In this paper, a real time simulation diesel engine model is simulation model code by hand, the method has accelerated the presented, which combines a mean value model [3]-[5], research of the hardware in the loop simulation. Through the in-cylinder model based on filling and emptying method [6] analysis of the simulation results of the several diesel engine and the NO, emission neural network (RN) model base on the models, the fast feasibility of this method has been vcrificd. adteNXelso erlntok(N oe aeo h reflection relationship between the amount of NO, and some Index Terms-diesel engine, NOx emission, neural network, influence factors. This combined model is the result of the real time simulation compromise between accuracy and computer time. Moreover a new simulation platform base on VxWorks target system and P4 PC ensures the real time demand. I. INTRODUCTION N owadys, the technology of diesel engine developed quickly in order to reduce fuel consumption and vehicle II. TURBOCHARGED DIESEL ENGINE DYNAMIC MODEL IN emissions. With the functions, complexity and control MATLAB/SIMULINK precision of engine electrical system (ECU) constantly increasing, the corresponding difficulty in developmentThe diesel engine model presented in this paper is established progress is also enhancing. For research and development the in Matlab/Simulink [7], [8]. In order to reach the trade-off engineers need tools to test and verify the reliability of new between simulation accuracy and computational overhead, the control strategies implemented in the ECU.
