Abstract(J)エンジンのピストンに装着されるオイルリングの下に発生する圧力は、オイル消費に影響を及ぼす。そこで圧力測定により発生メカニズム検討およびピストン設計が及ぼす影響の調査を行った。当該部圧力は、運転条件や流入する潤滑油量などの影響を受けること、オイルリング周辺の油穴は圧力低減に有効であることが示された。

Translation

Abstract(E)Oil pressure under the oil ring,which is installed in a piston of an engine, affects lubricating oil consumption. Pressure under the oil ring was measured by optical fiber type pressure sensor in this study. Mechanism of pressure generating under the oil ring and effect of the piston design on the pressure were investigated. They were found that engine operating condition or supply oil volume under the oil ring affected pressure and oil drain holes around the oil ring were effective for pressure reduction.

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.
