  • Patent number: 8347603
    Abstract: A method for metering a reagent which an emission control device situated in the exhaust duct of an internal combustion engine requires for removing at least one exhaust gas component from the exhaust gas and a device for executing the method are described. The fluid level of the reagent stored in a reagent tank is measured. The measured change in the fluid level is compared to at least one measure for the change in the fluid level calculated as a function of consumption. An error signal is output when the comparison result exceeds a predefined threshold value. This approach enables reliable information to be provided about the fluid level of the reagent in the reagent tank.

  • Patent number: 8348498
    Abstract: A procedure for checking the functionality of an electric heating device (10) with at least one PTC-element (13, 14) is suggested. The electric heating device (10) is operated at a battery voltage. When controlling the heating device (10) it is impinged with a current and at least one measuring value is detected, which represents the current that flows through the heating device. The measuring value for the current is compared to at least one reference value with a default tolerance width while considering the battery voltage. In the case of a measuring value that deviates from the reference value an error can be assumed.

  • Patent number: 8176726
    Abstract: A method for introducing a reagent medium into an exhaust gas conduit of an internal combustion engine, and an apparatus for carrying out the method. Provision is made for a diagnosis of the pressure sensor. In at least one first time interval in which a steady pressure state is expected, a check is made as to whether the pressure signal at least approximately corresponds to the steady-state pressure. In at least one second time interval in which a pressure change occurs, a check is made as to whether the pressure signal at least approximately corresponds to a predetermined test pressure and/or at least approximately exhibits a predetermined change with respect to the steady-state pressure. A fault signal is supplied if at least one of the conditions is not met.

  • Patent number: 8104268
    Abstract: A method for operating a metering valve and a device for performing the method, providing for diagnosis of the metering valve which defines a flow rate of a reagent to be introduced into an exhaust gas area of an internal combustion engine. The diagnosis is performed on the basis of an analysis of a measure for the flow rate during a diagnosis time. According to a first embodiment, after a diagnosis start signal has occurred with the metering valve closed, the reagent is brought to a predefined diagnosis starting pressure via a pump; the metering valve is then set at a predefined flow rate and the pressure difference occurring during the diagnosis time is analyzed. According to another embodiment, the amount of reagent delivered by the metering valve during the diagnosis time into a graduated beaker is analyzed.

  • Patent number: 7617674
    Abstract: A method for operating an exhaust-gas treatment device of an internal combustion engine and a device for carrying out the method, in which a reagent, whose pressure is measured by a reagent pressure sensor, is introduced into the exhaust-gas area upstream from the exhaust-gas treatment device. First the reagent pressure is brought to the exhaust-gas pressure which prevails in the exhaust-gas area upstream from the exhaust-gas treatment device. Then the pressure difference between the reagent pressure and the sum of the exhaust-gas pressure and the ambient air pressure is compared to a predefined pressure difference threshold, and if the pressure difference threshold is exceeded an error signal is supplied. The procedure contributes to an exact metering of the reagent through a diagnosis of the reagent pressure sensor.

  • Publication number: 20070163238
    Abstract: A method for metering a reagent into the exhaust gas flow of an internal combustion engine is provided, in which the reagent is guided in at least one component and in which a measure for the temperature of the component is recorded. The measure for the temperature is compared to a predefined temperature threshold value. A counter counts the number of times the threshold is exceeded. If the counter state exceeds a predefined count threshold value, a service signal is emitted. The temperature threshold value is fixed, for example, at the freezing temperature of the reagent. One embodiment provides that the counter counts an exceeding of the temperature threshold value only when the component is filled with the reagent.
