Abstract: The AVL BOOST engine model was developed. The engine universal characteristic was calibrated by modulating the throttle flow rate and combustion model parameters. The BOOST engine can be called by CRUISE in the background. The advantages of BOOST engine were listed. The BOOST engine was integrated in the CRUISE simulation environment under New European Driving Cycle. By analyzing the power and fuel consumption of engine and Integrated Starter-Generator (ISG) under urban and suburb cases, the result shows that the BOOST engine well simulates the engine transient process and can guide the control strategy optimization effectively.
