| 抄録(英) | Future Downsizing for gasoline engines will lead to higher boost ratio and specific torque than realized with todays engines. In the present paper, the vehicle integration of a 2-stage-turbocharging system into a middle class vehicle is discussed, starting with the adaptation of the combustion system to high boosting ratio by means of CFD supported Charge-Motion-Design-Process. Furthermore, the layout of the control concept had been supported by 1D-simulation of the overall engine/vehicle-system. Results from this work will be presented and compared to vehicle measurement data, leading to an assessment of optimization potential regarding drivability and discussing the sensor and actuator concept. 翻訳 |
