Turbocharger Model Characteristics
The Turbocharger Model is an extension for the diesel and gasoline engine models. It provides a more realistic model of turbocharger components and the engine air path than the map-based turbochargers models. It simulates an exhaust gas turbocharger that consists of a compressor, a turbine, and a turbocharger shaft. Turbochargers with variable turbine geometry (VTG) and wastegate can be simulated.
The turbine model calculates the mass flow, the output temperature, and the resulting power output according to wastegate or VTG position. The compressor and turbine are connected by a shaft, and the model provides the shaft speed. The compressor model calculates the boost pressure and the temperature in the compressor, using the equations for compressor power and compressor output temperature.
