In recent years, advanced automotive technologies have been developed to increase engine output power and improve fuel economy. In order to design dedicated control algorithms for these cutting-edge techniques, a control-oriented model is developed in this paper to capture the behavior of a turbocharged Spark Ignition Direct Injection (SIDI) engine with Variable Valve Timing (VVT). In the proposed model, mean value models are employed to simulate the cycle-average dynamics of the airflow system, while a discrete-event model is used to capture the reciprocating engine combustion cycle. This model, established in Simulink, has been parameterized using experimental data that are collected from a four-cylinder SIDI engine over a wide range of operation conditions. The dynamic performance of this model was validated with data collected during engine transients. In order to explore its modeling capability for flex-fuel applications, the performance of the model with gasoline-ethanol fuel E85 was also investigate.
