Abstract(E)	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.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
