Abstract (en)

[origin: WO2005052329A1] The invention relates to a multi-cylinder internal combustion engine and a method for the operation thereof. An exhaust gas duct and one respective gas intake valve (E) and gas discharge valve (A) are allocated to the cylinders. Furthermore, at least one of the cylinders (1-6) of the internal combustion engine (B) is provided with an additional discharge valve (Z) by means of which a flow connection is established between the combustion chamber and the exhaust gas duct in the open state thereof. According to the invention, an exhaust gas composition and/or an exhaust gas temperature which is/are different from the exhaust gas composition and/or exhaust gas temperature obtained during normal operation and support/s regeneration of an exhaust gas purifying unit that is disposed in the exhaust gas duct can be adjusted in connection with a regeneration mode used for regenerating said exhaust gas purifying unit by actuating the additional discharge valve (Z) of at least one cylinder. According to the inventive method, the additional discharge valve (Z) of at least one cylinder is at least temporarily opened in connection with a regeneration process of the exhaust gas purifying unit.
