    The invention relates to devices for controlled pressurization of internal combustion engines by means of a turbo-compressor consisting of a turbine and a compressor driven by an electric motor located on a common shaft.
    The purpose of the invention is to improve engine performance during acceleration,
    The drawing shows a control device diagram.
    The internal combustion engine 1 is equipped with a turbocharger 2 consisting of turbines A located on a common shaft 3 and a compressor 5. Turbine 4 runs on the exhaust gases of engine I. The electric motor 6 is made in the form of a reversible electric machine, connected by shaft 3 of a turbo compressor through coupling 7 coupling and connected via a current converter 8 to an electrical network 9, to which power is also supplied from diesel generator sets 10 and 11. Consumers 12 are connected to the network 9, such as heating systems, air-conditioning transformers, etc. . The control unit is made in the form of a computing device and, which is associated with a measurement 14 of the actual rotational speed of the turbocharger, made in the form of a tachogenerator, and / or a pressure sensor 15 developed by the compressor. In addition, a sensor 16 of the frequency of the network 9, which serves as an electrical energy storage device, is connected to the computing device 13.
    The computing device 13 is from comparing the set and actual values stored in the memory, in particular by the nature of the pressure change developed by the compressor or by the power characteristic; supplied to the electric motor 6, as a function of the internal combustion engine power, calculates the control actions for the control unit of the static current converter 8, in which, when the electric motor 6 is operated in the motor mode, the maximum acceleration and optimum conditions for smokeless combustion are achieved according to the coefficient excess air to burn.
    With an excess of energy in the exhaust gases:. M (the motor 6 is switched to the operation of the mode of the electric generator.

    The static current converter 8 is made primarily in the form of a pulsed inverter with an intermediate DC circuit and contains an inverter 17 driven from the electrical installation, connected via an intermediate DC circuit 18 to a reversible converter 19. The inverter 17 is controlled by a device 20 to which The control actions from the computing device 13 are controlled by the control device 13. Similarly to this for a reversing converter converter 19, a control device 21 is provided, which receives correspondingly The control action is from the calculating device 13, and the reference values are from the network 9.
    Depending on the power, the engine can be equipped with additional blocks 22 and 23 of the turbochargers, with each turbocharger being completed in the same way as the turbocharger 5 and also connected to the electric motor 6.
    The internal combustion engine 1 is equipped with a regulator 24 for controlling the flow of fuel through the fuel injection system 25. The power of the engine is predetermined by the sensor 26 of a predetermined parameter as a driver.
    In the generator mode of operation of the electric motor 6, the excess energy of the exhaust gases may be supplied as electrical energy to the network or supplied to an independent consumer 27.
    The switching of the electric motor 6 (reversible electric machine) to the generator mode and vice versa is carried out depending on the set pressure value developed by the compressor, or on the value calculated by the computing device 13, or on the power value of the internal combustion engine I. In this case, the control actions applied to the static current converter 8 determine the power delivered by the electric motor 6 in the generator mode. Additional advantages arise in the case of using a control unit in conjunction with a turbo compressor, which, based on calculations, has a number of turbine blades 4 and compressor 5
    providing an efficiency value such that in the upper partial load range of the engine 1 of the internal combustion, not all the exhaust gas energy is used, but the excess energy can be converted into electrical energy. Optimization is provided, for example, by the use of compressor wheels with curved blades and / or inlet guides.
    In the case of electric motors 6 in the form of asynchronous electric motors, when regulating the voltage and frequency, they operate like ordinary electric machines on a common network.
    The electric motors 6 can be made in the form of synchronous electric machines, in particular in the form of synchronous machines with constant excitation.
    It is advisable to make the electric motor 6 cooled by spraying oil. This ensures the compact design and the possibility of installing a suction silencer of turbochargers.
