Abstract
Le procédé décrit permet de réduire les émissions d'oxydes nitriques dans les gaz d'échappement d'un moteur Diesel au moyen d'une remise en circulation régulée des gaz d'échappement, lesquels sont refroidis et humidifiés dans un bain d'eau. Selon la présente invention, les gaz d'échappement produits par le moteur Diesel (1) sont acheminés dans une unité de nettoyage par voie humide (3) et une partie desdits gaz d'échappement acheminés dans l'unité de nettoyage par voie humide (3) est renvoyée vers le conduit d'aspiration (10) du moteur Diesel, de sorte que la quantité de gaz d'échappement remise en circualation est maintenue constante par rapport au volume total des gaz d'échappement.The method described makes it possible to reduce the emissions of nitric oxides in the exhaust gases of a diesel engine by means of a controlled recirculation of the exhaust gases, which are cooled and humidified in a water bath. According to the present invention, the exhaust gases produced by the diesel engine (1) are conveyed in a wet cleaning unit (3) and a part of said exhaust gases conveyed in the wet cleaning unit ( 3) is returned to the suction duct (10) of the diesel engine, so that the quantity of exhaust gas recirculated is kept constant with respect to the total volume of the exhaust gases.
