Title
(EN) EXHAUST GAS MIXER, SYSTEM, AND METHOD OF USING
(FR) MÉLANGEUR DE GAZ D'ÉCHAPPEMENT, SYSTÈME ET PROCÉDÉ D'UTILISATION
Abstract
(EN)
A segmented, heated urea mixer and an exhaust system to control NOx emission from combustion engines comprising a plurality of elements, at least one element independently heatable by an external power source to a temperature above a temperature of another element. A method of using the exhaust gas mixer and an exhaust gas mixer system further comprising a controller is also disclosed.
(FR)
L'invention concerne un procédé, un mélangeur d'urée chauffée et un système d'échappement pour réguler l'émission de NOx à partir de moteurs à combustion comprenant une pluralité d'éléments, au moins un élément pouvant être chauffé indépendamment par une source d'alimentation externe à une température supérieure à une température d'un autre élément. L'invention concerne également un procédé d'utilisation du mélangeur de gaz d'échappement et un système de mélange de gaz d'échappement comprenant en outre un dispositif de commande.
