Abstract(E)	This study analyzes degradation in automotive fuel vapor canisters compliant with North American ORVR regulations. ORVR strictly limits refueling emissions and requires working capacity exceeding non-ORVR systems. Activated carbon drives vapor adsorption, so capacity loss risks noncompliance. We examine whether temperature swings during repeated adsorption-desorption cycles cause material deformation and thermal shock that accelerate degradation. Additional factors, including fuel intrusion and condensation, are assessed for effects on capacity and durability. Finally, we outline research needs to quantify degradation, refine materials and designs, and develop accelerated tests and models that ensure long-term performance, reliability, and regulatory conformity of fuel canisters overall.

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".
