Title (EN) ADDITIONAL HEATING DEVICE FOR A MOTOR VEHICLE
(FR) DISPOSITIF DE CHAUFFAGE ADDITIONNEL D'UN VEHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to an additional heating device for a motor vehicle. The inventive device consists of: a unit heater which is heated by the internal combustion engine coolant; and a circuit for recycling the exhausts gases from the engine, comprising an exchanger (1) for cooling the exhaust gases, which is cooled by the engine coolant (2), said exchanger (1) being connected in parallel with the coolant circuit which is connected to the unit heater. The aforementioned exhaust gas recycling circuit comprises a valve (4) for controlling the flow of recycled exhaust gases to the engine intake (3). The invention is characterised in that the gas recycling circuit comprises a bypass (7) for directing the exhaust gases towards the exhaust manifold (6) of the engine, said bypass (7) comprising a valve (8) for controlling the exhaust gases returning to the exhaust (6).
(FR) Dispositif de chauffage additionnel d'un véhicule automobile comprenant un aérotherme qui est chauffé par le liquide de refroidissement du moteur à combustion interne de ce véhicule, un circuit de recyclage des gaz d'échappement de ce moteur qui comporte un échangeur (1) pour refroidir les gaz d'échappement qui est refroidi par le liquide de refroidissement (2) du moteur, cet échangeur (1) étant relié en parallèle avec le circuit du liquide de refroidissement qui est relié à l'aérotherme, le circuit de recyclage des gaz d'échappement comprenant une vanne (4) pour contrôler le débit des gaz d'échappement recyclés vers l'admission (3) du moteur, caractérisé en ce que le circuit de recyclage des gaz comprend une dérivation (7) des gaz d'échappement vers le collecteur d'échappement (6) du moteur, cette dérivation (7) comportant une vanne (8) pour contrôler le retour des gaz d'échappement vers l'échappement (6).
