FIELD: motors and pumps.
SUBSTANCE: invention is related to machine building and may be used in internal combustion engines, in particular, in systems of engines prestarting heating. System of prestarting heating of internal combustion engine with forced circulation of liquid coolant comprises eddy heat generator as heating element combined with circulating pump, drive of which is arranged in the form of air microturbine, which is connected by pneumatic network via electromagnet valve with compressed air receiver, three-way valve is installed on inlet pipeline in the point of its connection to heated circuit of engine with the possibility of radiator circuit disconnection with thermostat in mode of engine prestarting heating and its connection in mode of engine operation, and inlet pipeline is connected to inlet of circulating pump via additionally installed electromagnet valve.
EFFECT: acceleration of engine prestarting heating process and reduction of heat losses.
