| 摘要 |
An improved oil filler cap is presented, designed to support the reintroduction of super clean oil from a bypass oil filter attached to a gasoline or diesel engine. The improved filler cap is designed to be shorter in height than state-of-the-art bypass filler caps, removing an unneeded structure supporting the nozzle receiving the super clean oil. This invention is directed towards vehicles with low hood clearance in their engine compartments.
