FIELD: mechanical engineering; heat engines.
SUBSTANCE: proposed automatic control system of supercharging air temperature contains fan, three-way crossover device with drive and supercharging air cooler installed in intake manifold between supercharger and cylinders and bypass line included into manifold and accommodating second three-way crossover device with drive and supercharging air gas heater washed by exhaust gases. Metering of supply of exhaust gases is provided by second three-way crossover device whose drive is connected with supercharging air temperature sensor installed in intake manifold between supercharging air cooler and cylinders. Fan drive is also connected with supercharging air temperature sensor. Shaft of fan is connected with shafts of two similar induction motors with phase-wound rotors whose stator windings are connected to ac generator driven by shaft of internal combustion engine which is controlled by control unit connected with first output of microprocessor controller. Rotor windings of induction motors being connected in series are connected to rectifier, to output of which semiconductor thermoelectric cooler and winding closing unit are connected, the latter being connected to second output of microprocessor controller. Stator of one of induction motors is made rotating, being connected with drive connected to third output of microprocessor controller. Drives of first and second three-way crossover devices are connected to fourth and fifth outputs of microprocessor controller. Supercharging air temperature sensor is connected to input of microprocessor controller. Invention provides maintaining of temperature of supercharging air in internal combustion engine at optimum levels depending on engine operating conditions irrespective of ambient temperature.
EFFECT: reduced energy consumption for cooling, increased efficiency of air-gas cooling and supercharging air heating system.
