摘要： A method for operating a device for providing a liquid additive having at least one suction point for removing liquid additive from a tank, a valve-free conveying line extending from the suction point to a supply unit, and a valve-free displacement pump, the displacement pump being configured to convey the liquid additive from the tank via the suction point along the conveying line to the supply unit, the displacement unit having at least one seal of the conveying line, displaceable along the conveying line for conveying the liquid additive, includes: a) detecting a stoppage of operation of the device; b) establishing a position of the seal within the positive-displacement pump; and c) changing the position of the seal if the position of the seal does not correspond to a provided park position of the seal.

摘要： An apparatus for reducing soot particles in exhaust gas, particularly of an internal combustion engine, includes first and second at least partially electrically conductive structures with an intermediate space therebetween, a high voltage source forming a potential between the first and second structures and at least one at least partially electrically conductive intermediate structure in the intermediate space receiving an intermediate potential. A method for treating the exhaust gas includes conducting exhaust gas from the first to the second structure and applying a high voltage at least temporarily between the first and second structures. At least part of the soot particles in the exhaust gas is ionized or agglomerated and deposited on the second structure. A high voltage between potentials of the first and second structures is applied at least temporarily to the intermediate structure. An electric field is influenced favorably and disruptions from undesirable voltage flashovers are reduced.

摘要： A device for evaporating a predeterminable volume of fluid provides for successive addition of partial volumes of the predeterminable volume to a supply line at different adding rates, at least partially evaporating the partial volumes forming a vapor film between them and a supply line wall, conveying the partial volumes through the supply line to an evaporator surface, and applying the partial volumes to an evaporator surface region varying as a function of mass and/or volume adding rate of the partial volume, permitting effective evaporation of fluid, particularly urea/water solution. Utilization of the highest possible proportion of evaporator surfaces is achieved by mass and/or volume addition rate-dependent distribution of impingement surfaces on the evaporator surface. This heating strategy in the supply line region ensures the Leidenfrost effect when individual partial volumes are added. As even a distribution as possible is achieved using a corresponding geometrical configuration of the evaporator channel.
