Abstract
The application of computational methods for the development of the whole engine-vehicle system has been evaluated in this paper, to highlight the potential of computer simulation techniques applied to the analysis of engine-vehicle matching.
First, engine performance was simulated using a one-dimensional fluid dynamic code, and predicted data were compared to experimental results, to assess the accuracy of the engine computer model not only as far as gross engine performance parameters are concerned, but also for the prediction of pressure values at several locations inside the engine. The simulation was also extended to the whole engine operating range, including part-load operating conditions.
Afterwards, a vehicle simulation code was employed, to predict vehicle performance and fuel consumption. The vehicle model was validated through a detailed comparison of the computer simulation results with experimental data, including both main acceleration performance and average fuel consumption values over typical driving cycles (ECE, EUDC).
Finally, engine and vehicle simulation techniques were coupled and applied to the analysis of the impact of engine modifications on vehicle performance, and they have been proved to be powerful and effective instruments to identify the modifications required to achieve the vehicle performance targets.
