FIELD: transport.SUBSTANCE: invention relates to automotive control device. Proposed device comprises catalyst, heat exchanger, air conditioner and fan. Actuation of fan 21 in air conditioner 18 is prohibited during the period from engine start to termination of catalyst warm-up. This prevents air passage in air duct 22 with fan switched on and heat exchange with coolant in heater core 24 in circulation channel 6. After transfer of heat generated by the engine to coolant heat cannot be fed inside passenger cabin 25 which fast increase in engine temperature and coolant temperature thus increasing temperature of engine exhaust gases. Heat generated by the engine 1 is distributed preferably to catalyst located outside passenger cabin 25 that must be heated at low temperature by exhaust gases.EFFECT: efficient transfer of heat to catalyst.28 cl, 18 dwg |
