  • Publication number: 20200355107
    Abstract: A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine (200) with the following steps: set up (111, 116) a pressure difference model, which models a measured pressure difference (?p) which drops across the particulate filter (210) as a function (220) of a volume flow ({dot over (V)}) through the particulate filter (210) with an offset value (a0, C); measure (120) multiple measurement values (245) for the pressure difference (?p) at different volume flows ({dot over (V)}) and solve (130) the pressure difference model as a function of the pressure difference (?p), whereby the offset value (a0, C) is also determined.

    Abstract: A fuel filter insert for a fuel filter has a low-pressure region with prefilter element arranged therein. A high-pressure region arranged fluidically downstream of the low-pressure region has a main filter element arranged therein. Prefilter element and main filter element are arranged one atop the other axially in the fuel filter insert. A wall element projects away from the main filter element in axial direction and extends at least partially through the prefilter element. Low-pressure region and high-pressure region at least over sections thereof are separated from each other by the wall element. A fuel filter is provided with a filter housing in which the fuel filter insert is arranged. The filter housing has a fuel outlet and a fuel inlet for fuel prefiltered by the prefilter element. Fuel inlet and fuel outlet are fluidically positioned between low-pressure region and high-pressure region and a fuel pump is connectable thereto.

  • Patent number: 10752178
    Abstract: A motor vehicle includes a tailgate that is upwardly pivotable in a rearward upward manner and on which a load compartment cover is pivotably held around a pivot axis by way of the rear end region of the load compartment cover that faces the tailgate. The load compartment cover, in a region that is spaced apart from the pivot axis by way of at least one force transmission element, is held on a vehicle body. The force transmission element, when the tailgate is upwardly pivoted, pivots the load compartment cover toward the tailgate so as to expose an access to the load compartment. At least one hook connection connects the tailgate to the load compartment cover and establishes the pivot axis.

  • Patent number: 10668410
    Abstract: A fuel filter has a filter housing and a fuel filter insert exchangeably arranged in the filter housing and provided with a prefilter element and a main filter element. Prefilter element and main filter element are positioned one behind the other in the filter housing in axial direction of the filter housing. A fuel discharge channel is arranged in the filter housing below the fuel filter insert. In operating position of the fuel filter insert in the filter housing, the raw sides of prefilter element and of main filter element are sealed relative to the fuel discharge channel by seal-tight contact of the fuel filter insert on the filter housing. The raw side of the main filter element, when the fuel filter insert is moved by axial movement away from the operating position, is fluidically connected with the fuel discharge channel via the raw side of the prefilter element.

  • Patent number: 8818594
    Abstract: A method is provided for operating a hybrid vehicle (1) having an internal combustion engine (2), an electric machine (4) and having a regenerable filter device that absorbs fuel vapors from a fuel tank of the internal combustion engine. To improve the reproducible operation of a hybrid vehicle with an internal combustion engine and an electric machine, in a purely electric driving mode in which the hybrid vehicle (1) is driven only by the electric machine (4), the regenerable filter device is rinsed by switching on the internal combustion engine (2) with a scavenging strategy that is dependent on the velocity of the hybrid vehicle (1).
