Abstract(J)	エンジンのオイル消費低減のためには，ピストンリングのオイル掻き落とし性のみならず，リング溝とのシール性の担保が不可欠である．今回，その評価のためにリング溝周辺へ光ファイバを設置しLIF法にて油膜厚さ計測を実施した．光ファイバの導入にはリンク装置を用い，保持構造の工夫により高回転域での計測を可能とした． Translation
Abstract(E)	Towards realizing low oil consumption in the engine, it is critical to optimize not only the oil scraping performance of the piston ring but also the sealing performance. The LIF method was used to measure the behavior of the oil film around the oil ring by installing optical fibers on the 3rd land, the top of the groove, and the back of the groove. The optical fiber is introduced by a linkage system, and the special holding structure enables measurement in a high rotation range.

About search

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.
