Abstract(J)モーターサイクル用直噴水素エンジンのシリンダヘッドに複数の熱流束センサを配置し,得られた瞬時熱流束結果から火炎伝播挙動を解析するとともに,同条件のCFD解析や筒内可視化の結果と比較検証し,空気過剰率など運転条件によって変化する筒内の火炎伝ぱ挙動を把握した.

Translation

Abstract(E)Multiple heat flux sensors were placed on the cylinder head of a motorcycle direct-injection hydrogen engine. The instantaneous heat flux results obtained were used to analyze flame propagation behavior. Furthermore, CFD analysis and in-cylinder visualization results under identical conditions were compared to understand the cylinder flame propagation behavior dependent on operating conditions, such as the excess air ratio.

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.
