Abstract

Véhicule automobile (V, V’) comprenant un système de récupération d’eau dans les gaz d’échappement comprenant : - une chambre de condensation (30) d’un mélange enthalpique air extérieur/gaz d’échappement pour en extraire l’eau, disposée dans la ligne d’échappement, - un système de captation et d’acheminement d’air extérieur (40, 40’, 40’’, 43, 44), ayant une connexion fluidique avec la ligne d’échappement, - un réservoir primaire (301) situé dans ou en aval de ladite chambre de condensation et qui fournit l’eau récupérée qui alimentera le moteur, et un réservoir secondaire (302) situé en amont de la chambre de condensation, - des moyens de circulation (33) de l’eau récupérée permettant au moins une circulation de l’eau dudit réservoir primaire vers ledit réservoir secondaire et dudit réservoir primaire vers le circuit d’alimentation du moteur en eau récupérée. Figure à publier avec l’abrégé : Fig. 1Motor vehicle (V, V') comprising a system for recovering water in the exhaust gases comprising: - a condensation chamber (30) of an enthalpy outside air/exhaust gas mixture in order to extract the water therefrom , arranged in the exhaust line, - a system for capturing and conveying outside air (40, 40', 40'', 43, 44), having a fluidic connection with the exhaust line, - a primary tank (301) located in or downstream of said condensation chamber and which supplies the recovered water which will supply the engine, and a secondary tank (302) located upstream of the condensation chamber, - circulation means (33 ) recovered water allowing at least one circulation of water from said primary tank to said secondary tank and from said primary tank to the motor supply circuit with recovered water. Figure to be published with abstract: Fig. 1
