Title (EN) METHOD FOR PURIFYING EXHAUST GAS OF AN INTERNAL COMBUSTION ENGINE
(FR) PROCÉDÉ D'ÉPURATION DES GAZ D'ÉCHAPPEMENT D'UN MOTEUR À COMBUSTION INTERNE
(DE) VERFAHREN ZUM REINIGEN VON ABGAS EINER VERBRENNUNGSKRAFTMASCHINE
Abstract:
(EN) Method for purifying exhaust gas of an internal combustion engine (2) having at least one combustion chamber (3), comprising at least the following method steps: a) burning of fuel with a first air quantity in the at least one combustion chamber (3), b) conducting of the exhaust gas to at least one catalytic converter (8), c) introducing of an additional air quantity via at least one of the combustion chambers (3) to the at least one catalytic converter (8), and d) converting of pollutants in the exhaust gas by way of chemical reactions of the exhaust gas at least with the additional air quantity in the at least one catalytic converter.
(FR) L'invention concerne un procédé d'épuration des gaz d'échappement d'un moteur à combustion interne (2) comprenant au moins une chambre de combustion (3). Le procédé comprend au moins les étapes de procédé suivantes consistant : a) à brûler le carburant avec une première quantité d'air dans la ou les chambres de combustion (3), b) à guider les gaz d'échappement en direction d'au moins un catalyseur (8), c) à introduire une quantité d'air additionnelle par l'intermédiaire d'au moins une des chambres de combustion (3) en direction du ou des catalyseurs (8), et d) à faire réagir les polluants dans les gaz d'échappement par réaction chimique des gaz d'échappement au moins avec la quantité d'air supplémentaire dans le ou les catalyseurs.
(DE) Verfahren zum Reinigen von Abgas einer Verbrennungskraftmaschine (2) mit mindestens einem Brennraum (3) umfassend zumindest die folgenden Verfahrensschritte: a) Verbrennen von Kraftstoff mit einer ersten Luftmenge in dem mindestens einen Brennraum (3), b) Leiten des Abgases zu mindestens einem Katalysator (8), c) Einleiten einer zusätzlichen Luftmenge über mindestens einen der Brennräume (3) zu dem mindestens einen Katalysator (8), und d) Umsetzen von Schadstoffen im Abgas durch chemische Reaktionen des Abgases zumindest mit der zusätzlichen Luftmenge in dem mindestens einen Katalysator.
