    The invention relates to engine building, and in particular to devices for a two-stage engine boost.
    Known devices for pressurizing an internal combustion engine with one exhaust gas expansion stage and one air compression stage combined into a pressure wave exchanger. These devices provide a short duration of transient engine conditions, i.e. its high throttle response [1].
    However, the boost pressure of such devices is limited.
    Devices are also known that provide a higher boost pressure by two-stage air compression. These devices contain two stages of air compression connected to the receiver and two stages of expansion of exhaust gases connected to the exhaust manifold, paired in turbocompressor 10 and a wave pressure exchanger connected to the engine in the form of two successive stages of pressurization, and the wave pressure exchanger is made in the form of a high pressure stage, and a turbocompressor in the form of a viscous pressure stage.
    The pressure exchanger installed as a high-pressure stage allows to increase the temperature of the exhaust gases without complicating the design (due to the fact that there is no need to cool the pressure exchanger cells) and converting the pressure pulsations of the exhaust gases to the pressure pulsations of charge air, which can subsequently be used C2].
    However, at the same time, the rotor · 1 масса mass of the turbocompressor is large, which does not make it possible to fully use the possibilities of reducing the duration of transient regimes by using a pressure wave exchanger.
    The purpose of the invention is to reduce the duration of the transient conditions of the engine.
    To achieve this goal, the turbocharger is made in the form of a high pressure stage, and the pressure exchanger is in the form of a low pressure stage.
    The turbocharger can be configured to use exhaust pressure pulses, and the pressure exchanger to use a constant exhaust pressure.
    An intermediate heater can be installed between the exhaust gas expansion stages, which can be included in the exhaust pipe of the engine.
    An intermediate cooler with a refrigerant inlet pipe can be installed between the stages of air compression; a valve can be installed in this pipe. An air cooler can be installed between the turbocharger and receiver.
    Figure 1 shows a simplified diagram of the proposed device, figure 2 is the same with a heater and cooler.
    An automobile engine 1 has an average effective pressure much greater than 15 kgf / cm.
    The turbocharger 2 is a turbine 3 of the first stage of expansion of the exhaust gases, combined with the compressor 4 of the second stage of compressed air, and is made in the form of a stage of high pressure. The wave pressure exchanger (VOD) 5 is made in the form of a low pressure stage, and a silencer 6 is installed on its exhaust. An air filter 7 is connected to the suction inlet of the VOD. In order to coordinate the turbocharger and the VOD, an intercooler 8 is installed between them to cool the air between the compression stages. An air cooler 9 · is installed between the tour-, bocompressor and engine receiver
    A two-stage pressurization makes it possible to carry out an intermediate heating of the gases after expansion in the high-pressure stage and thereby increase its enthalpy, i.e., its working capacity in the low-pressure stage. At high exhaust gas temperatures, it is advisable to carry it out with the help of an intermediate heater 10 installed between the exhaust gas expansion stages $ and included in the engine exhaust line. This reduces the temperature of the gases in front of the turbocharger, which improves its working conditions.
    to Turbocharger. 2 can be made with the possibility of using exhaust pressure pulses in the turbine 3, the wave pressure exchanger VOD 5 with the possibility of using a constant exhaust pressure. A valve 11 is installed in the refrigerant inlet pipe.
    When the engine is running, its exhaust gas enters the turbine 3 20 of the turbocharger 2 and partially expands, giving energy to the drive of the compressor 4. Finally, the gases expand in VOD 5, giving the expansion energy to the compressed air. After the first stage in VOD, the air is cooled in the intercooler 8 and enters the compressor 4, which is the second stage of compression. Before entering the engine, the compressed air is cooled in the air cooler 9. In the case of an intermediate heater 10, the gases in front of the turbine are cooled and heated before the water supply.
    If the load does not change, the speed of the rotors of the turbocharger and the VOD remains constant. With increasing load, the rotor speed increases. Moreover, due to the implementation of the turbocompressor as a high-pressure stage, its size and mass are reduced, its acceleration time is reduced, and the duration of the transient conditions 45 of the engine is reduced.

    The purpose of the invention is to reduce the duration of motor transients. To achieve this goal, the turbocharger is designed as a high pressure stage, and the pressure exchanger is designed as a low pressure stage. The turbocharger can be performed with the possibility of using exhaust pressure pulses and the pressure exchanger with the possibility of using a constant pressure of the exhaust gases. An intermediate preheater may be installed between the exhaust expansion stages, which may be included in the engine exhaust manifold. An intercooler with a refrigerant inlet pipe can be installed between the air compression stages, and a valve can be installed in this pipe. An air cooler can be installed between the turbocharger and the receiver. Figure 1 shows a simplified diagram of the proposed device; figure 2 - the same, with a heater and cooler. Automotive engine 1 has an average effective pressure of much more than 15 kgf / cm. The turbocharger 2 is a turbine 3 of the first expansion stage of the exhaust gases, combined with the compressor 4 of the second stage of compressed air, and made in the form of a high pressure stage. The wave pressure exchanger (HPA) 5 is designed as a low pressure stage, and a silencer 6 is installed on its exhaust. An air filter 7 is connected to the inlet of the VOD. In order to reconcile the turbocharger and the VOD, there is an intercooler 8 between them for cooling the air between the compression stages. An air cooler 9 is installed between the turbocharger, the booster compressor and the receiver of the engine. At high exhaust temperatures, it is advisable to carry it out using an intermediate preheater 10 installed between the exhaust expansion stages and included in the exhaust line dvigdtel. This reduces the temperature of the gases in front of the turbocharger, which improves its working conditions. The turbocharger. 2 may be configured to use exhaust pressure pulses in the turbine 3, a UDF 5 wave pressure exchanger with the possibility of using a constant exhaust pressure. A refrigerant I valve is installed in the refrigerant inlet. When the engine is running, its exhaust gases flow into the turbine 3 of the turbocharger 2 and partially expand, giving energy to the compressor 4 drive. Finally, the gases expand to the VOD 5 giving expansion energy to the compressed air. After the first stage in the VOD, the air is cooled in the intercooler 8 and enters the compressor k, which is the second stage of compression. Before entering the engine, the compressed air is cooled in the air cooler 9. In the case of an intermediate preheater 10, the gases in front of the turbine are cooled, and before the VOD it is heated. If the load does not change, the rotational speed of the rotors of the turbocharger and the high-voltage generator remains constant. As the load increases, the rotational speed of the rotors increases. Moreover, due to the performance of the turbocharger as a high pressure stage, its size and weight are reduced, its acceleration time is reduced, and the duration of the transient modes of the engine is reduced. Claims 1. Internation device for internal combustion engine comprising two stages of air compression connected to the receiver and two stages of expansion of exhaust gases connected to the exhaust line combined in pairs in a turbocharger and a wave pressure exchanger connected to the engine in the form of two
