| 抄録(英) | 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. 翻訳 |
