摘要： A method for determining an amount of liquid removed from a tank per unit time includes discontinuously feeding the liquid to exhaust gas of an internal combustion engine by at least feeding the liquid through an injection line into the exhaust gas, measuring pressures simultaneously at least at two points in the injection line and determining an amount of liquid fed in per unit time from the measured pressures. The amount of liquid removed between a first point in time and a second point in time is further derived by integrating the amounts of liquid removed per unit time over a period of time from the first point in time to the second point in time. The method allows the precise consumption of the liquid to be calculated and the remaining amount of liquid in the tank to be additionally determined. On-board diagnosis is further possible with the method.

摘要： An assembly includes a honeycomb body secured by an inner casing tube in a housing, in particular a housing of an exhaust system of an internal combustion engine. The inner casing tube has an overall length which is bounded axially by two edges and is substantially smaller than the axial length of the honeycomb body. The inner casing tube is also disposed in an approximately axially central position around the honeycomb body and is connected, in particular brazed, thereto in at least one axial connection region. The inner casing tube has a region within the axial connection region in which it is connected to the honeycomb body on the inside or attached directly adjacent the latter on the outside and is connected to the housing. Regions of the inner casing tube which are not connected to the housing but are connected to the honeycomb body toward the inside are constructed as radially elastic spring elements. In this way, a resilient attachment, which adapts to deformations of the honeycomb body, is produced without tearing. That is advantageous in particular in the case of honeycomb bodies made of very thin sheet-metal layers, in particular thinner than 0.03 mm.

摘要： A system and a method are provided for determining a pollutant concentration of an exhaust gas at a first position of an exhaust-gas system of an internal combustion engine. A sensor for determining the pollutant concentration is placed at a second position, downstream of the first position, in the exhaust-gas system. The sensor records a measured value, which is then transmitted to a time function element taking into account the time delay between recording a measured value at the first and second positions and transmitting the measured value, temporally correlated with other undelayed measured values, to a diagnosis unit. Sensitive gas sensors can thus be placed at cooler positions of the exhaust-gas system that are less exposed to vibration and can nevertheless determine the pollutant concentration at another position.

摘要： The method and the novel device clean exhaust gas containing nitrogen oxide from an internal combustion engine. Liquid ammonia is preferably added as reducing agent from a reducing agent reservoir through a reducing agent line and a metering device through the use of open loop or closed loop control synchronously and/or phase-displaced in a relation to the corresponding output of exhaust gas from the combustion chamber and in portions adjusted to the quantities of NOx generated. The synchronized and quantitatively adjusted addition of ammonia allows for NOx and ammonium emissions to be kept low with a catalytic converter disposed downstream and having a small storage volume.
