  • Method and apparatus for conversion of NO
    Patent number: 7225612
    Abstract: The invention refers to a method and apparatus for converting NOx and comprises the step of controlling a temperature in a NOx-LNT by adsorbing NOx in the LNT at a temperature below a predetermined temperature value to a predetermined value being the maximum amount of NOx to be stored at the predetermined temperature value, thereafter heating the LNT to the predetermined temperature value, and thereafter starting a regeneration process by addition of reducing agents.

  • Method for providing an oil change indication to an operator of an internal combustion engine
    Patent number: 7188514
    Abstract: A method for providing an oil change indication to an operator of an internal combustion engine having an exhaust-after-treatment system requiring regeneration, The method includes detecting regeneration events performed on the exhaust-after-treatment system; detecting oil temperature events each time unit an oil temperature is over a threshold value, and providing the oil change indication to the operator as a function of the detected regeneration events and the detected oil temperature events.

  • Method for regenerating an exhaust gas catalyst
    Publication number: 20060086081
    Abstract: The invention relates to a method for regeneration of a nitrogen oxide storage catalyst for a direct injected compression ignition engine. According to the invention, regeneration can be accomplished by adjusting air flow into the engine and controlling fuel injection to give a number of small part-injections during an expansion stroke of an engine cylinder.
