A heating system for use on an exhaust system having an exhaust gas passageway, the engine having a cooling system to circulate a cooling fluid to and from the engine, includes a fuel-dosing member for dosing fuel to the exhaust system to trigger a regeneration event. A particulate filter is located on the exhaust gas passageway downstream of the engine, and an oxidation catalyst member is located upstream from the particulate filter. The oxidation catalyst member oxidizes the fuel dosed to increase the temperature of the exhaust gases. The increased temperature causes a regeneration event at the particulate filter, which further increases the temperature of the exhaust gases. A heat exchanger is located downstream of the particulate filter for capturing heat from the exhaust gases. The heat exchanger has an inlet conduit and an outlet conduit for circulating the cooling fluid from the heat exchanger to the engine cooling system.

Un système de chauffage destiné à être utilisé sur un système d'échappement doté d'un passage de gaz d'échappement, le moteur possédant un système de refroidissement pour faire circuler un fluide de refroidissement vers et depuis le moteur, comprend un élément de dosage du carburant pour le dosage de carburant vers le système d'échappement afin de déclencher un événement de régénération. Un filtre à particules est situé sur le passage de gaz d'échappement en aval du moteur, et un catalyseur d'oxydation est disposé en amont du filtre à particules. L'élément catalyseur d'oxydation oxyde le carburant dosé pour augmenter la température des gaz d'échappement. L'augmentation de la température provoque un événement de régénération sur le filtre à particules, qui augmente en outre la température des gaz d'échappement. Un échangeur de chaleur est disposé en aval du filtre à particules pour capturer la chaleur des gaz d'échappement. L'échangeur de chaleur comporte un conduit d'entrée et un conduit de sortie pour la circulation du fluide de refroidissement de l'échangeur de chaleur pour le système de refroidissement du moteur.
