Abstract: An exhaust cleaning system for motor vehicles, especially a diesel exhaust cleaning system for medium to heavy utility vehicles. The exhaust cleaning system has an exhaust muffler (1), a catalytic converter (2) and an exhaust particle filter element (3). The exhaust muffler (1), the catalytic converter (2) with a U-shaped tubular urea injection element (4) arranged upstream and an exhaust particle filter element (3) are integrated in a common housing and designed as a structural, functional unit.

Abstract: The invention pertains to a heating apparatus (1), in particular, an auxiliary heater and/or a parking heater for a motor vehicle, with a one-piece or one-part housing (2) that contains a combustion chamber shaft (3), in which a heat transfer casing (8) is arranged, wherein the inner side (9) of said heat transfer casing encloses a combustion chamber (5) and is subjected to hot exhaust gases during the operation of the heating apparatus (1), wherein the outer side (11) of the heat transfer casing forms the inner envelope of a cooling fluid space (10), through which a cooling fluid flows during the operation of the heating apparatus (1), wherein the outer envelope of said cooling fluid space is formed by the inner side of the combustion chamber shaft (3), and wherein the housing (2) also contains a catalyst shaft (4), in which at least one catalytic element (15) is arranged through which hot exhaust gases flow during the operation of the heating apparatus (1).

Abstract: A fiber mat is configured such that the fibers 2 of an intermediate layer arranged between two adjacent layers touch the fibers of one of the layers at positions situated at a distance from the contact points with the fibers of the other layer. The positioning and the material of the fibers is designed to have a high elasticity with regard to pressing.

Abstract: An exhaust elbow (1) is provided with a single exhaust outlet (2) with an outlet mounting flange (3) and at least two exhaust inlets (4, 5, 6) with an inlet mounting flange (7) for fastening on the engine block of a motor vehicle. The exhaust guiding of the exhaust elbow (1) between the inlet mounting flange (7) and the outlet mounting flange (3) is formed by a single-walled sheet metal hood (8) forming a collection line. The sheet metal hood (8) surrounds all exhaust inlets (4, 5, 6) together, without individual pipes being formed. Such a simple sheet metal elbow can be manufactured at a low cost and with low weight and nevertheless has sufficient ability to function, is dimensionally stable and can be used in a versatile manner.

Abstract: A heater, especially a liquid fuel-operated water heater (10) or air heater of a motor vehicle in the form of an auxiliary heater or a parking heater has a housing jacket (1) and a heat exchanger (2) as well as with a control device (11) for regulating or monitoring the heating operation via at least one temperature sensor (3), especially a regulating temperature sensor and/or overheating sensor. The temperature sensor (3) is arranged on the underside of a control device bottom plate (4) facing the temperature sensor (3) on the housing jacket (1), wherein the temperature sensor (3) extends through an opening of the housing jacket (1), especially a water jacket, in the direction of the heat exchanger (2) and is preferably pretensioned by a spring. As a result, the temperature sensor can be mounted on the control device bottom plate already during the manufacture of the control device and finally mounted together with the control device bottom plate rapidly and reliably.

Abstract: A heating system (1) is provided mounted in a motor vehicle with an internal combustion engine. The system (1) includes an additional heating system (2 or 3) or an auxiliary heating system (4). The additional heating system (2 or 3) or the auxiliary heating system (4), or a part thereof, is made in the shape of a modular component mounted on or connected to interfaces (I, II, III, IV) of the heating system which are specific for each vehicle. The modular component can optionally be replaced by another modular component of the same type.
