  • SCR-injection unit
    Patent number: 8622316
    Abstract: An SCR-injection unit includes an injector, a sleeve element for fixing the injector to a flange of an exhaust gas pipe, and a cooling body. According to the invention, the sleeve element has an elongated thin-walled connecting section, one axial end of which is indirectly connected to the flange of the exhaust gas pipe and the other axial end of which is indirectly connected to a supporting structure for the injector.
    Type: Grant

  • Method for operating a catalytic converter used for purifying the exhaust gas of an internal combustion engine and a device for implementing the method
    Patent number: 7546728
    Abstract: A method for operating a catalytic converter used for purifying the exhaust gas of an internal combustion engine, and a device for implementing the method, which provide for an open-loop or closed-loop control of the reagent fill level in the catalytic converter to a predefined storage setpoint value. The targeted stipulation of the storage setpoint value ensures, on one hand, that in non-stationary states of the internal combustion engine, there is a sufficient quantity of reagent available for the completest possible removal of at least one unwanted exhaust-gas component, and on the other hand, a reagent slip is avoided.

  • Process and system for controlling the mixture composition for a spark ignition Otto engine with an NOx storage catalyst during a regeneration phase
    Patent number: 6871492
    Abstract: A process and a system are used for controlling the mixture composition for an Otto engine with an NOx storage catalyst during a regeneration phase. The process includes controlling, to the value of one, a ?-value (?M) of an exhaust gas fed to the NOx storage catalyst during a regeneration phase as a function of a ?-value (?K) of an exhaust gas emitted by the NOx storage catalyst. The system includes a control device for controlling, to the value of one, a ?-value (?M) of the exhaust gas fed to the NOx storage catalyst during the regeneration phase as a function of the ?-value (?K) of the exhaust gas emitted by the NOx storage catalyst.
