Title (EN) ENERGY RECOVERY SYSTEM FOR AN INTERNAL COMBUSTION ENGINE
(FR) SYSTÈME DE RÉCUPÉRATION D'ÉNERGIE POUR MOTEUR À COMBUSTION INTERNE
Abstract:
(EN) The energy recovery system (12) comprises: an exhaust line (1) which is capable of collecting exhaust gas from an exhaust manifold of the engine and which is equipped with a particulate filter (2); a secondary line (13) which is thermally linked with, but distinct from, the exhaust line (1), and which carries a fluid. The particulate filter has a filtering part in which exhaust gases can flow and a heat exchanging part in which said fluid can flow, the filtering part and heat exchanging part being arranged to transfer heat by conduction from the exhaust gases to said fluid. The secondary line is connected to energy recovery means capable of recovering energy from said heat.
(FR) L'invention porte sur un système de récupération d'énergie (12) qui comporte : une ligne d'échappement (1) qui peut capter des gaz d'échappement à partir d'un collecteur d'échappement du moteur et qui est équipée d'un filtre à particules (2) ; une ligne secondaire (13) qui est reliée thermiquement avec la ligne d'échappement (1), mais qui en est distincte, et qui transporte un fluide. Le filtre à particules a une partie de filtration dans laquelle les gaz d'échappement peuvent s'écouler et une partie d'échange de chaleur dans laquelle ledit fluide peut s'écouler, la partie de filtration et la partie d'échange de chaleur étant disposées pour transférer de la chaleur par conduction des gaz d'échappement audit fluide. La ligne secondaire est reliée à un moyen de récupération d'énergie pouvant récupérer de l'énergie à partir de ladite chaleur.
