Abstract(J)フォトクロミズム可視化手法をモータリング運転の可視化ディーゼルエンジンに適用し,ピストンランド上におけるオイル挙動を観察した.吸気負圧とトップリング/セカンドリングの合口位置を変化させて実験を行い,これらの影響を明確にするとともに,ランド上のオイル量が油膜流れに強い影響を与えていることを確認した.

Translation

Abstract(E)The photochromism visualization technique was applied to the optical diesel engine under motoring operation to visualize the oil behavior on the piston land. The experimental parameters are the intake negative pressure and the position of the ring gaps for both of the top ring and the second ring, and the effect of these parameters were confirmed. Furthermore, it is made clear that the amount of oil existed on the land gives a large effect on the movement of oil film.

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.
