Abstract(J)エンジン実働状態のピストン摩擦力を高回転まで計測する浮動ライナー方式の計測技術を開発した.特徴は,ライナーを高い剛性で保持する両側支持構造の採用と,振動ノイズのキャンセル方法を新規に導入した点である.これにより,最大4000r/minまで高い繰り返し精度(FMEP 3σ<0.5kPa)でピストン摩擦力を計測できることを確認した.

Translation

Abstract(E)A new floating liner measurement equipment was developed. With the equipment, piston friction force under actual engine operating conditions can be evaluated across a wide range of engine speeds. The key features of the equipment are follows; 1) implementation of a support of both-side of liner; 2) introduction of a new vibration noise cancellation method. With these features, the equipment can measure of the piston friction force with high repeatability (FMEP 3σ < 0.5 kPa) up to 4000 r/min.

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.
