Abstract(J)車両燃料系システムからの蒸散HCの大幅低減を目的に、燃料バリヤ層にFEPフィルムを配置した新規のフューエルフィラーホースを開発した。本技術により、ホースとしての性能は従来と同等を維持しながら、E10燃料の透過量を約1/10に削減することが可能となった。本燃料ホースをセントラPZEV('10MY)へ車載した。

Translation

Abstract(E)In order to reduce the evaporative hydrocarbon emissions from vehicle fuel system, new laminate fuel filler hose was developed. The new hose consists of inner FKM layer wrapped with fluorinated ethylene propylene (FEP) film barrer layer, and outer ECO layer. This new reduced the fuel permeation with the E10 fuel to less than one-fifth compared to current filler hose, without any negative effect on fuel resistance or flexibility. This new FEP hose is installed on 2010 model year PZEV Sentra.

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.
