  • the invention relates to mechanical engineering, in particular to internal combustion engines operating using gas turbine pressurization.
  • turbocharging devices in internal combustion engines (“Tuning automobile engines” St. Moscow, VN Stepanov, 2000 p. 55; International annual catalog “Global Sourcing Guide 2006”, p. 216), in which the increase in air supply the intake manifold is provided by using the energy of the exhaust gases to drive an air compressor.
  • the use of turbocharging allows for the burning of more fuel, resulting in increased engine output compared to the power obtained under natural suction conditions.
  • turbocharging provides fuel savings per unit of power and reduced exhaust gas toxicity due to more complete combustion of the fuel.
  • a disadvantage of the known devices is the lack of automatic adjustment of the turbocharging value, which can lead to both thermal overload and even destruction of the turbine at high engine speeds, and to low efficiency at low speeds due to the presence of the so-called "Turboyama". Its presence is explained by the fact that at low speeds or immediately after a sharp depressing of the gas pedal, the pressure of the exhaust gases differs little from atmospheric pressure, as a result of which the rotation speed of the turbocharger impeller is not sufficient to compress the intake air to the desired volume. As a result of this there is a shortage of air in the combustible mixture and its component - oxygen, which reduces the engine throttle response.
  • Turbocharging devices are known, described, for example, in RF patent N “2425991 and patent application US20130152583, in which automatic adjustment of the degree of turbocharging is provided by changing the geometry of the turbocharger according to the corresponding commands of the control unit.
  • a change in the flow of exhaust gases entering the turbine blades is provided to optimize power for a given load.
  • the guide vanes of the turbine move apart, protecting from exceeding the speed and maintaining the boost pressure at the level required for the engine.
  • the above devices are characterized by insufficient reliability due to resource wear of moving parts, as a result, excessive backlash occurs in the blade control mechanism and deposits appear that violate the mobility of its parts.
  • the presence of a large amount of carbon deposits leads to a decrease in the mobility of parts and their subsequent jamming. For this reason, the position of the guide vanes no longer corresponds to the control action or, as a last resort, the guide vanes do not rotate at all. As a result, the pressure of the charge air is no longer adequate for the stable operation of the engine.
  • the known turbocharger device comprises a turbocharger including a turbine, the inlet of which is connected to the output manifold of the internal combustion engine, and the outlet is connected to the atmosphere, and a compressor, the output of which is connected to the intake manifold of the internal combustion engine through the cooler and throttle, the air filter, the input of which is connected to the atmosphere, a bypass valve that is connected between the ICE exhaust manifold and the turbine output, a bypass valve that is connected between the throttle valve input and the compressor input, and the control unit phenomena, the information inputs of which are connected to sensors installed on the engine, accelerator pedals, as well as the inputs of the air filter and throttle, and the corresponding outputs are connected to the control inputs of the throttle, bypass valve and bypass valve.
  • An intercooler is used as a charge air cooler in the known device, which is a heat exchanger consisting of a system of thin tubes bent by a “snake” and plates located between them. The plates increase the surface area of the intercooler and provide better heat transfer from the charge air to the atmosphere.
  • the intake air is filtered and compressed in a turbocharger to produce charge air, which is then cooled and fed to the intake manifold of the internal combustion engine.
  • the temperature and pressure of the charge air are measured, the values of which regulate the speed of rotation of the turbocharger by means of a controlled supply of part of the exhaust gases to the atmosphere, bypassing the turbocharger.
  • the charge air is cooled by atmospheric air when passing through the intercooler.
  • This device provides control of the charge air in the intake manifold of the internal combustion engine, and, as a result, increase the dynamics of control of the internal combustion engine operation mode.
  • the throttle response of the internal combustion engine is improved, that is, the response time of the internal combustion engine operating mode to a control action is reduced, for example, pressing the accelerator pedal.
  • the control of the charge air flow entering the internal combustion engine intake manifold is carried out by the control unit by the signals of the accelerator sensor, as well as by the signals of the temperature and pressure sensors installed on the inlet and outlet pipes, the engine block, and at the compressor output, by changing the position of the throttle valve, bypass and bypass valves.
  • the programmed control algorithm ensures maximum approximation of the adjustment range to the previously selected upper and lower limits of the compressor shaft rotation speeds taking into account the temperature and pressure of the intake and charge air, as well as the internal combustion engine operating mode.
  • the known device is characterized by insufficiently high dynamics of control of the flow of charge air, and, as a consequence, the mode of operation of the internal combustion engine.
  • This is due to the use of an intercooler in a known device, which is an inertial link in the path of charge air to the intake manifold of the internal combustion engine. Before the charge air passes the path from the compressor to the intake manifold of the internal combustion engine, it must fill the entire system of tubes of the intercooler.
  • each bend of the tube creates additional resistance to the flow of charge air passing through it, which generally reduces the speed of passage of charge air on the way from the compressor to the ICE intake manifold. Due to the fact that the intercooler creates resistance to the flow of charge air passing through it, the pressure at the outlet of the intercooler decreases, and therefore, to obtain a given pressure in the intake manifold of the internal combustion engine, it is necessary to increase the pressure at the compressor outlet, which leads to an additional increase in the temperature of the charge air.
  • a disadvantage of the known device is also the fact that when the bypass valve is activated, hot charge air enters the compressor inlet and raises the already high temperature at its outlet. That is, the effect of a closed ring occurs, leading to a significant increase in temperature and a decrease in the density of charge air, which ultimately also leads to a decrease in the dynamics of engine control.
  • the basis of the invention is the development of a device for a turbocharged internal combustion engine, in which the organization of cooling the charge air in the operating mode of the engine, as well as heating the intake air during engine start-up and warm-up, would increase the dynamics of controlling the turbocharging of the internal combustion engine.

  • the technical result of the claimed device for turbocharging an internal combustion engine is to increase the dynamics of control of a turbocharger, that is, reducing the reaction time of the engine to a control action. This is achieved due to the constructive implementation of the charge air cooler, in which the heat exchange between the inlet atmospheric and charge air is organized, and due to the controlled inlet air cooler, which provides cooling of the inlet atmospheric air before being fed to the turbocharger.
  • the inlet air temperature controller introduced into the device provides the formation of a control signal for the controlled inlet air cooler in order to maintain a predetermined temperature of the atmospheric air at the compressor inlet.
  • An additional increase in the dynamics of control of the turbocharging of the internal combustion engine provides the implementation of cooling plates on the outer side surface of the charge air duct, which reduces the thermal resistance between the elements of the charge air cooler and the atmosphere, reduces the temperature of the charge air and increases its density at the inlet of the throttle valve.
