Abstract(J)CO2排出量削減に貢献する世界初の圧縮着火ガソリンエンジン(SKYACTIV-X)の商品化にあたり、エンジンの能力を最大化するための保温とこれまでのエンジンよりも大きくなる音の抑制が課題であった。これに対しエンジンを丸ごと包むカプセル化構想を打ち立て、必要な部位を緻密に導き出し、効率的な構造を実現して課題を克服した。

Abstract(E)In commercializing the world's first compression ignition gasoline engine (SKYACTIV-X) that contributes to the CO2 reduction, the challenges were to keep warm to maximize the engine performance and to suppress noise that is louder than conventional engines. In response to this, we established an encapsulation concept that encloses the entire engine, precisely derived the necessary parts, and realized an efficient structure to overcome the issues.

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".
