Simulation of the Drive-Off Performance with Turbocharged Diesel Engines

Downsizing of combustion engines is nowadays a key technique to provide fuel efficient propulsion systems. Although, emission targets are fulfilled, the transient response may be insufficient in terms of drivability. This paper discusses an approach to simulate the transient performance of a turbocharged diesel engine. The model is then incorporated with a drivetrain model, allowing studies on drive-off performance and clutch control mechanisms. Future applications of the model are discussed, especially the role of the model as an integral part of a virtual calibration approach for drive-off behavior.
