Abstract(J)	ピストンリングの低張力化がガソリンエンジンのピストン摩擦力とオイル消費に及ぼす影響について検討するために，浮動ライナ法とSトレース法により両者の同時測定を行った．各リングの低張力化による摩擦力とオイル消費への寄与率について解析を行い，その原因をピストンおよびリング周りの油膜観察により確認した． Translation
Abstract(E)	This study was aimed at clarifying the effect of lower tension pisotn rings on piston friction and lubricating oil consumption(LOC). Floating liner method and sulfur tracer method were applied simultaneously to measure the piston fiction and LOC with gasoline engine. This paper described how each ring tension acts on both piston frictio nand LOC. In order to verify the reasons, oil film behavior around the piston and rings were observed by the engine with optical glass window.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
