Abstract: A vehicle, such as a motor home or camper or the like, includes a living space expansion that can be set up as needed and has a space volume, which, in the set-up state, is connected with an interior space volume of the vehicle. The living space expansion includes at least three wall sections, wherein at least two of the wall sections are each configured as side walls, wherein at least of the one wall sections is configured to be moved out of the interior space volume to form the living space expansion. At least one of the wall sections of the living space expansion can be a hollow chamber wall section. The hollow chamber wall section can be an inflatable hollow chamber wall section or a self-inflating hollow chamber wall section.

Abstract: The present invention relates to a motorhome, mobile home or similar travelling or recreational vehicle comprising at least one sanitary area in which a water closet device is mounted. The water closet device comprises at least one seat element and is connected to a current source which carries out a waterless flush operation.

Abstract: A method and a device for operating an internal combustion engine make it possible to monitor a temperature sensor or a lambda sensor in an exhaust system of the internal combustion engine for functionality in the entire operating range of the internal combustion engine. To that end, the plausibility of the signal of the temperature sensor is checked with a signal of the lambda sensor for a predetermined relationship.

Abstract: A method for checking at least three sensors which detect a measured quantity in the area of an internal combustion engine. A measure of the sensor signal of the particular sensor to be checked is compared to a reference signal which is obtained from at least one part of the sensor signals of the sensors to be checked. A sensor is recognized as defective on the basis of a comparison of the measure for the sensor signal with the reference signal. The reference signal is formed, for example, from a mean value of a measure of the sensor signals of at least one part of the sensors to be checked, the individual sensor signals being weighted using correction factors in forming the mean value. The sensors are temperature sensors or pressure sensors, for example, which may be situated in an intake area of the internal combustion engine, on the internal combustion engine itself, in an exhaust area, and/or in an exhaust gas treatment system.

Abstract: Provided are a method and device for operating an internal combustion engine having exhaust-gas recirculation, the method and device allowing a diagnosis of an exhaust-gas recirculation cooler during normal operation of the internal combustion engine. In this context, a variable characteristic of the functioning of the exhaust-gas recirculation cooler is monitored. The variable characteristic of the functioning of the cooling device is ascertained as a function of a measured value. The variable characteristic of the functioning of the exhaust-gas recirculation cooler is specified on the basis of an intact exhaust-gas recirculation cooler. The ascertained value of the variable characteristic of the functioning of the exhaust-gas recirculation cooler is compared to the predefined value. An error is detected when the ascertained value of the variable characteristic of the function of cooling device deviates from the specified value.

Abstract: A method and a device for storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, as described. Data on the fuel pump and/or the injector is assigned to at least one electronic component. The data is taken into account by a control unit in controlling the fuel metering system. The component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.

Abstract: A method and an apparatus for controlling an internal combustion engine are described. At least one sensor serves to detect a first variable that characterizes the pressure in the combustion chamber of at least one cylinder. A second variable, which characterizes the maximum value of the change and/or the location of the maximum value of the change, is determined on the basis of this first variable. This second variable serves to control operating parameters of the internal combustion engine in an open-loop and/or a closed-loop manner.

Abstract: A common rail injector is proposed which offers great freedom in designing the course of the preinjection main injection and of the injection pressure. Moreover, it offers improved security against leaks into the combustion chamber, caused for instance by a leaking nozzle needle valve seat.

Abstract: in a fuel injection valve having a valve body, having a control pressure chamber that is disposed inside the valve body and is closed at one end by an actuating part, which is for an injector needle and can be moved in the control pressure chamber between a closed position and an open position, having an inlet into the control pressure chamber, and having an outlet from the control pressure chamber that is controlled by a control valve, the opening speed of the injector needle should be increased. To this end, the mouth opening of the inlet into the control pressure chamber is disposed so that it is at least partially closed by the actuating part when the actuating part moves from the closed position into the open position.
