Abstract(J)次期排気ガス規制対応のエンジン技術として、副室ジェット燃焼が注目されている。本発表では、モデルベースによる副室設計プロセスとして、CFD解析に基づく副室内の掃気改善、および燃焼-熱の連成解析に基づく冷却性能に関する検討結果について報告する。また、製作したパッシブ型副室の単気筒エンジン試験結果を紹介する。

Translation

Abstract(E)Pre-chamber jet ignition is one of the promising engine technologies for complying with the next pollutant emission regulation. In this presentation, as a model-based design process, the investigation results of the improvement of gas-exchange in the pre-chamber and cooling performance based on CFD analysis will be reported. In addition, the single cylinder engine test results of the passive type pre-chamber will be introduced.

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.
