Stated content

  1. Communication summary

    本予備情報は、2020年の温暖月における冬用燃料の使用と、これが引き起こす可能性のある走行性能の問題について通知するものです。継続中のコロナウイルス(COVID-19)パンデミックにより、走行および燃料使用量が大幅に減少しています。パイプライン/ステーションに貯蔵されている冬用燃料の過剰在庫があるため、EPAは燃料蒸気要件を免除しています。これにより冬用燃料の使用が夏季まで延長されます。走行性能に関する懸念は単発の事象ではなく、暑い日に関連する複数回の発生であるべきです。 Machine translation (unreviewed)

    This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use.  Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement.  This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
