combustion, moreover, the system contains a compressor, a water-air heat exchanger, a water separator and a vortex tube with a damped hot end connected in series, while the cold end of the vortex tube is connected between the outlet of the charge compressor and the inlet of the internal combustion engine, the inlet of the vortex tube is connected to the output of the compressor through a water separator and a water-air heat exchanger and the compressor inlet is connected to the atmosphere, the second cavity of the air-water heat exchanger is connected to the water cooling system of the engine ator internal combustion engine, and comprises a second vortex tube plugged with the hot end, a cold end of which is connected to the input of the charge in the compressor and input - with the atmosphere RF application №95109034 / 06 IPC: 6 F01P / 00 publ.20.04.97

The technical result includes improving the dynamic properties of the engine by efficiently supplying air to the engine cylinders with the help of an electric fan, while balancing the air pressure in the receiver with the help of electromagnetic valves, as well as providing additional purification of crankcase gases from the combustion products in the radiator and maintaining fuel consumption optimality feed into the engine.

This result is achieved due to the fact that the forced air supply system to the internal combustion engine contains a device for supplying compressed air, an air heat exchanger and a moisture separator. An electric fan with a control unit is used as a device for supplying compressed air, and a radiator for cooling gas coolers in

in the form of a V-shaped metal tube equipped with inlet and outlet hoses designed for condensation of crankcase gases. The outlet hose is equipped with a fitting mounted on the duct connecting the air filter and the mass air flow sensor with the receiver through the throttle. To set the air pressure in the receiver, the system is equipped with six solenoid valves. The control unit is equipped with a D.11Y relay to turn on the electric fan in the vehicle electrical system.

The forced air supply system to the internal combustion engine 1 is illustrated in FIG. 1 and consists of an electric fan 2 with a control unit 3, a crankcase gas cooling radiator 4 in the form of a V-shaped metal tube equipped with inlet and outlet hoses. The outlet hose is equipped with a fitting 5 mounted on the duct 6. Air duct b connects the air filter 7 through the mass air flow sensor 8 to the receiver 9 through the throttle valve 10. To set the air pressure in the receiver 9, the system is equipped with six solenoid valves 1. A set of six solenoid valves 11 is equipped with nozzles 12 connecting them to the air duct 6 through the throttle valve 10 and nozzles 13 connecting them to the receiver 9.

The control unit 3 is equipped with a relay for switching on the electric fan 1 in the vehicle electrical system 14.

The system of forced air supply to the internal combustion engine operates as follows:

when engine 1 reaches 1500-2000 rpm, a signal is received from the standard sensor of the throttle control 10 and through the control unit 3 the electric fan 2 and a set of solenoid valves 10 are turned on.

The air entering the working cylinders of the electric motor 1 from the electric fan 2 increases the compression ratio of the fuel mixture due to the greater filling of the cylinders with air. From the engine 1, the crankcase gas enters the radiator 4, then through the nozzle 5 into the air duct 6 through the tube turned in the direction of the main air flow. Part of the cleaned crankcase gases through the nozzles 11, 1, 2 and 3 of the electromagnetic valves 10 and nozzles 12 is fed into the receiver from the side opposite to the main air flow, increasing the pressure in the receiver at the 1,2 and 3 cylinders of the electric motor 1. The remaining valves are used to redistribute the pressure in the receiver for 4,5 and 6 cylinders of electric motor 1. The forced air supply system proposed as an invention is installed on vehicles with electronically controlled fuel injection and is intended to increase oschnosti engine during overtaking or some other situation or due to a sharp increase in the speed of the car, as well as to improve the car's acceleration working in direct drive, besides the system improves the dynamic properties of the motor.
