An engine model allowing real-time computation and having a high degree of reusability was developed for application as a system design tool and as hardware in the loop system (HILS) for electronic control unit (ECU) development.A distinctive feature of this model is that it is composed of simple models of engine parts. These parts are units in which the gases flow through the engine, they are modeled by applying the law of energy and mass conservation.The model was installed in a rapid prototype system and used to conduct a comparison with an actual vehicle while it was in operation. The results of the comparison confirmed that the engine air inlet mass rate, the pressure, and temperature in the inlet and exhaust pipes could be predicted with acceptable accuracy.
