A vehicle component for a motor vehicle includes a coupling device including two couplable coupling elements configured to provide, in a coupled state, a fuel-tight connection of two fuel-conducting lines. One of the coupling elements is in a form of a metallic female element which is fixedly connectable to one of the two lines, and an other one of the coupling elements is in a form of a metallic male element which is fixedly connectable to an other one of the two lines. The male element, for coupling purposes, is insertable into the female element, wherein, in the coupled state, an axially extending overlap section with at least one radial seal device is formed between the female element and the male element. A securing device is configured to secure the coupling elements in the coupled state against inadvertent release from one another.

Vehicle component and motor vehicle

A pressure tank system for a motor vehicle has a fuel tank () operated in a differential pressure range between a low pressure and a high pressure. To ensure a simple construction and can be produced cost-effective construction, the low pressure is between ambient pressure minus 50 hectopascals ambient pressure and plus 50 hectopascals.

Pressure tank system for a motor vehicle

A fuel system () for a motor vehicle internal combustion engine, having a fuel tank () with a fuel vapor venting path () containing an activated carbon filter (), in which a fresh air stream () blown or sucked in the direction of the tank venting valve () by an independent pump unit () arranged close to the activated carbon filter () can be made to flow through the activated carbon filter (), at least at the periphery thereof and, in that case, preferably at the fresh air side to regenerate said filter.

Fuel system

A method is provided to prevent an undesirable flooding or breaching of an activated charcoal filter during the operation of a hybrid vehicle or of a motor vehicle with automatic start/stop. The method includes monitoring during the operation of the vehicle at least one factor that has an effect on the fuel evaporation and using the monitored factor to prevent an undesirable flooding or breaching of the activated charcoal filter.

Method for operating a fuel evaporation retention system

A refueling device () for refueling a fuel tank () of an internal combustion engine () in a motor vehicle () has a filler connector () for feeding fuel to the fuel tank (). An integrated fuel feed device () feeds the fuel from the filler connector () to the fuel tank ().

Refueling device and motor vehicle having such a refueling device

A filler pipe for a fuel tank of a motor vehicle includes at its cap end a cylindrical insert whereby an elastic sealing ring is arranged between an outer surface of the insert and an inner surface of the filler pipe made of plastic material. In order that a simple cost-favorable connection between the insert and the filler pipe is achieved combined with a good seal, the profiled sealing ring having an elongated cross-sectional shape is mounted on the insert under prestress. Furthermore, the insert and sealing ring are subjected to a common blow-molding operation.
