  • Method for operating an internal combustion engine
    Patent number: 7152573
    Abstract: In a method for operating an internal combustion engine with exhaust gas purification system, a rich-burn mode of the internal combustion engine with a rich exhaust gas composition or a lean-burn mode of the internal combustion engine with a lean exhaust gas composition is set alternately, and the quantity of fuel which is introduced during a combustion cycle of the internal combustion engine is introduced by at least one preinjection, at least one main injection and at least one afterinjection.
    Type: Grant
    Filed: February 7, 2004
    Date of Patent: December 26, 2006
    Assignee: DaimlerChrysler AG
    Inventors: Oliver Abet, Gernot Hertweck, Thomas Muehleisen, Marco Stotz

  • Method for operating an internal combustion engine using exhaust gas purification system, and internal combustion engine
    Patent number: 6820415
    Abstract: In a method for operating an internal combustion engine using exhaust gas purification system, and internal combustion engine, the method for operating an internal combustion engine with exhaust gas purification system, in which a rich mode of the internal combustion engine with a rich exhaust gas composition and a lean mode of the internal combustion engine with a lean exhaust gas composition are set alternately, and by the exhaust gas purification system with a rich exhaust gas composition ammonia is synthesized and stored and with a lean exhaust gas composition nitrogen oxides are reduced to form nitrogen by means of the stored ammonia.
