    摘要: In a motor vehicle having exhaust-gas recirculation, fluid of an air-conditioning circuit is used to cool coolant of a dedicated hydraulic circuit, which in turn cools recirculated exhaust gases in a two-stage heat exchanger, thus increasing engine gain by replenishing to reduce NOx emissions. A method differentiates control strategies for the circuits, as a function of vehicle driving conditions, continuous modes and transient braking and acceleration modes, to compensate for consumption of the compressor of the air-conditioning circuit. The circuits include a heat exchanger for heat exchange between the air-conditioning fluid and coolant, a bypass, capable of accumulating and releasing cold energy, and, optionally, a line condensing water vapour of the exhaust gases and reinjecting the condensed water to the intake.
