    A method of, and apparatus for, intercooling the charge air of a pressure-charged internal combustion engine by way of an air-cooled heat exchanger, the internal combustion engine being pressure-charged by a gas-dynamic pressure-wave machine. The entire quantity of outside air drawn in by the pressure-wave machine is divided into a partial stream of scavenging air and a partial stream of charge air. The scavenging air flows through the heat exchanger as a coolant and upon leaving the latter performs its intended scavenging function in the pressure-wave process, and the charge air, having been compressed in the pressure-wave process, is intercooled in the scavenging air-cooled heat exchanger.

    1 in the first compartment I suck up the “nozzle.
    Part of the air line with heated air cooler surfaces can be located in the first compartment of the suction nozzle and the air cooler can be made recuperative with a transverse coolant medium.
    Fig. 1 shows a wave pressure exchanger with a built-in air cooler; in fig. 2 - sweep over jBHaMeTpy rotor / passing over the height of the cells and over adjacent parts of m.
     FIG. 1, such non-essential elements as, for example, engine connection parts, supports, as well as the outer contours of the air and gas receivers are not shown. In addition, the pressure exchanger is shown as single-cycle, this is reflected in the fact that both gas and air sleep raiders are each is only one, ping to the rotor, a high window and a low pressure window, with no gas windows being shown. For the sake of clarity, the system functions in FIG. 1 shows arrows showing the movements of working media and the direction of rotation of the rotor.
    The cistern 1, divided into cells 2 parallel to its axis, forming 1 91e, an annular adep and open at the ends, is located between the end plates 3 and 4 "To the windows 5 and b of the plate 3 are connected the suction nozzle 7 and the air pipe 8, to the window the end plate 4 - channel 9 of the inlet and channel 10 of the exhaust gases of the engine. The suction pipe 7 is divided by partition 11 into two first 12 and second 13 compartments. In the first QTcei.S, the cooled surfaces of the air cooler 14 are located, the heating of which is located in the air pressure line 8. For this, part of this line with heated air cooling surfaces is located in the first compartment 12 of the suction inlet (see figure 1). In this case, the air cooler is recuperative with the transverse washing of the cooled medium. Windows 5 and 6 in the end plate 3 and the window in the end plate 4 communicated with exhaust exhaust channel 10, JS iiun are such that during rotation of the rotor compartment 12 through the rotor cells communicate with channel 10, and compartment 13 with the woody J5yonoporn highway 8.
    The hot exhaust gases of the engine of internal combustion through channel 9 enter the cells 2 of the rotor, expand and leave the pressure exchanger through channel 10. On the air side, fresh air is sucked through pipe 7 and the window 5 into the cells of the rotor, is compressed in them by the exhaust gases and leaves the exchanger pressure as charge air through the air pressure line 8.
    Cell compression and expansion processes are schematically shown in FIG. 2. When gases and air move inside the cells, a gas-filled chamber 15 and an air-filled chamber 16 are formed. In the chamber 15, the gases expand and then are removed through the channel 10, while in the chamber 16 that part of the intake air that enters exchanging pressure directly and then being pushed into line 8. The rest of the intake air is blown through the rotor cells into exhaust flue 10, as indicated by arrow 17. This channel flushing is important and should be maintained at all lions This ensures that the cells are cleared from the engine exhaust gas and the cell walls are cooled.
    In the suction process, air is divided into two streams in the suction inlet, the first of which, coming through compartment 12, is used as a cooler, is sent to a wave pressure exchanger and is discharged from the latter along with the exhaust gas, as shown by arrow 17, and the second is fed through the compartment 13 to the pressure exchanger directly and after being compressed, it is discharged into the air-supply line 8, and then cooled in the air cooler 14 with the first intake air flow. The first air flow leaves the air cooler with a higher temperature than the temperature of the environment, and therefore only dp is used to purge the rotor cells leaving the cell in the next cycle. Its temperature is low enough to effectively cool the cells. The temperature of the cooled compressed air depends, among other things, on the degree of regeneration of the applied heat exchanger. Since this should also take into account the pressure loss in the heat exchanger, the choice of the air cooler is an optimization problem that must be solved in each individual case.
    For example, to cool the intake air to a temperature with a compression ratio of 2.5 and a suction temperature of 20 ° C, a decrease in air temperature occurs by 85 ° C. Approximately by the same value. Maybe in the sum of cooling of compressed air and cells of 1: 3 degree the air temperature of the first stream, since to create the effect of cooling the cells, its temperature should not exceed the temperature of the exhausted compressed air. Accordingly, it should be 105 ° C at MejiHO. It follows that for maximal cooling of supraventricular air, the blowing ratio should be approximately 1.1, which corresponds to the amount of air in the first stream, approximately equal to 40% of the total amount of air in the two streams. At lower engine loads, the purge rate can be significantly reduced to ensure the health of the pressure exchanger, but this is unacceptable because of the need for the OPP to wait for the engine's charge air.
    The described method and apparatus for its implementation, in addition to the advantages usually created by cooling the charge air, make it possible to increase the efficiency of the engine by rational use of air, both for pressurization and cooling.
