Abstract(J)エンジンのオイル消費低減は環境負荷改善に重要である。今回、そのオイル消費低減を図るため、2ピースオイルリングのレール間に流入したオイルを窓穴から排出しやすい新断面形状を開発した。本報ではCFD解析とDOEを用いた設計手法、可視化・実機評価による実証実験結果、新形状の効果について報告する。

Translation

Abstract(E)Reducing the oil consumption is desired for the environmental impact. In order to reduce the oil consumption, we developed a new cross-sectional shape of 2-piece oil control ring which accelerate the oil flow to behind the ring through the oil drain slots. In this paper, we discuss the design method and the reducing effect of oil consumption by new cross-sectional 2-piece oil control ring used CFD analysis related DOE and used the visualization and the evaluation of experiment.

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.
