In a method for operating a fuel system of an internal combustion engine, the fuel system has a fuel tank and a ventilation device having at least one ventilation valve for ventilating the fuel tank in the direction of a device that generates a negative pressure, at least intermittently. A magnitude of deformation caused by an internal pressure of the fuel tank of the fuel tank is measured and, if the magnitude of deformation exceeds a threshold, the ventilation valve is closed and/or a bypass is opened.

A device for ventilating a fuel tank of an internal combustion engine in particular of a fuel tank of an internal combustion engine of a motor vehicle includes an activated carbon filter and at least one valve which is controllable by a control unit. To prevent leakage of hydrocarbons into the environment without enlargement of the activated carbon filter the control unit controls the valve in dependence on a load factor of the activated carbon filter and/or in dependence on an operating cycle duration of the internal combustion engine.

The invention relates to an activated charcoal filter (10) for storing and releasing gaseous hydrocarbons which originate from a fuel supply means of a motor vehicle. The activated charcoal (14) can be supplied with gaseous hydrocarbons via an inlet (16). A heating means for heating of the activated charcoal (14) is made available by a tank shutoff valve (18) by means of which the inlet (16) can be shut off. Since the tank shutoff valve (18) is being operated as a heating means, an additional heating means for regenerating the activated charcoal (14) can be omitted. Furthermore, the invention relates to a motor vehicle with such an activated charcoal filter (10) and a method for operating an activated charcoal filter (10).
摘要:
A method and a fuel tank system for adjusting a pressure in a fuel tank are described. Evaporated fuel tank escapes from the fuel tank under overpressure with respect to the ambient and is transferred to a temporary storage for at least one substance of the evaporated fuel. A venting means, through which the evaporated fuel escapes, is controlled by at least one parameter different from a pressure or at least one information provided in form of data. The pressure in the fuel tank can thereby be more variably adjusted.

A coupling device for tubes and/or pipes comprising two substantially identical plate-type coupling parts is provided. Each coupling part has an even number of openings to receive inserted plug-in couplings configured as plug parts or socket parts. In one embodiment, the receiving openings for plug parts are arranged mirror-symmetrically across an axis of symmetry from the receiving openings for socket parts. The plug and socket parts are joined by first inserting and securing them into their respective receiving openings in the two coupling parts, then connecting the coupling parts.

A connection device for the plug connection of at least one media line includes a housing part with at least one reception orifice for plugging in a plug portion connected or connectable to the at least one media line. The housing part includes a basic part and an insert part. The basic part is releasably connected with a form fit to the insert part via a latching connection. The latching connection holds the insert part releasably and is formed by a C-shaped spring clip which is seated on the outside of the basic part and engages with at least one latching extension radially through an orifice of the basic part into a circumferential latching groove of the insert part.

The present invention relates to an electrically heatable media line comprising a fluid line and at least one line connector, which comprises a fluid connector connected to a line end of the fluid line and an outer housing. The fluid line and the line connector each have electrical heating means, wherein the fluid connector is enclosed at least in the region of the heating means and together with an end section of the fluid line by the housing. The housing has fixing means for accommodating, in a mechanically fixing manner, the fluid connector with the connected line end and electrical conductors and conductor connectors of the heating means.

The invention relates to a tank venting system for a fuel tank (12) of a vehicle, having a vent line (14) for discharge of gaseous hydrocarbons from the fuel tank (12) during refueling thereof. Gaseous hydrocarbons originating from the fuel tank (12) can be introduced in a filler pipe (20) of the fuel tank (12) via a recirculation line (24). A control device (34) controls a proportional valve (32) and changes in this way a pass-through cross section of the recirculation line (24). In this way, a load of an activated charcoal filter (16) which is coupled with the vent line (14) can be minimized. The control device (34) can especially determine a pressure in the fuel tank (12). Furthermore, the invention relates to a method of venting a fuel tank (12) during refueling thereof.
