[Industrial applications]

 The present invention relates to a supercharged engine including a supercharger such as an exhaust gas turbine supercharger.

[0002]

[Prior Art]

 2. Description of the Related Art In recent years, internal combustion engines such as vehicles are generally equipped with a supercharger capable of improving output.

As shown in FIG. 4, conventionally, in this type of supercharged engine, a compressor 3 is arranged in the middle of an intake passage 2 of an engine 1, and a turbine 5 is arranged in the middle of an exhaust passage 4 to provide a supercharger 6. A catalyst 7 and a muffler 8 are provided on the downstream side of the turbine 5 to purify and muffle the exhaust gas, and an air cleaner 9 is provided on the upstream side of the compressor 3 to pressurize clean outside air and It is designed to be supplied to the combustion chamber 10. Further, when the air is compressed by the compressor 3, the intake air temperature rises due to adiabatic compression. Therefore, the intercooler 11 is provided on the downstream side of the compressor 3 so as to prevent the decrease of the charging efficiency.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional supercharged engine, the compressed air of the supercharger 6 is exclusively supplied to the engine 1, and it cannot be said that it is necessarily used in various ways. That is, if a part of the compressed air can be used for heating and cooling in a vehicle requiring a blower by adding a simple mechanism to the supercharger 6, it is possible to contribute to simplification and downsizing of those devices.

In view of the above circumstances, the present invention was devised to provide a supercharged engine that can effectively use the pressure of the supercharger with a simple mechanism.

[0006]

[Means for Solving the Problems]

 The present invention has a cylindrical chamber on the downstream side of a compressor such as an exhaust gas turbine supercharger and is supplied with compressed air from the compressor in the circumferential direction, so that hot air that can be used for in-vehicle air conditioning, etc. It is equipped with a vortex scooter / heater that produces cold air.

[0007]

[Action]

 With the above configuration, hot air and cold air from the vortex scooter / heater can be used for cooling and heating and intake air cooling, and the compressed air of the supercharger can be effectively used.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a supercharged engine according to the present invention. This supercharger unit is configured by providing a vortex scooter / heater 22 having a cylindrical chamber 21 on the downstream side of the compressor 3 of the exhaust gas turbine supercharger 6.

The exhaust gas turbine supercharger 6 is composed of a turbine 5 and a compressor 6 coaxially connected to each other by a rotating shaft 23 as in the conventional case, and a compressor 3 is provided in an intake passage 2 of an engine 1. A turbine 5 is arranged in the exhaust passage 4. The intake passage 2 is branched on the downstream side of the compressor 3, and the branch passage 24 is connected to the vortex scooter / heater 22 so that part of the compressed air from the compressor 6 is supplied.

As shown in FIG. 2, the vortex scooter / heater 22 has, for example, an inlet pipe 25 and an outlet pipe 27 for introducing compressed air to one end side in the axial direction of the chamber 21, and another one on the other end side. Each outlet pipe 26 is provided. The inlet pipe 25 is attached to the peripheral surface of the shell 28 that defines the chamber 21 so as to extend in the circumferential direction (tangential direction of the circular cross section), and the spiral swirling airflow A can be formed in the chamber 21. Is becoming. Further, one outlet pipe 26 is attached to the outer peripheral portion of the shell body 28, and the other outlet pipe 27 is attached to the central portion of the shaft end face so as to extend in the axial direction, and each discharges the air in the chamber 21. .. A control valve 31 is provided in the outlet pipe 26 so that the flow rate distribution between the high temperature side and the low temperature side can be changed.

The air injected in the chamber 21 in the circumferential direction becomes a high-speed vortex and turns toward the hot air outlet 26 while swirling. A part of the gas is discharged from the discharge port 26, but the rest becomes a swirl flow at a relatively low speed in the central portion toward the cool air discharge port 27. At this time, heat is transferred to the outer high-speed vortex from the center low-speed vortex, and the center side becomes low temperature and the outer side becomes high temperature, and is taken out from the outlets 27 and 26 as cold air and hot air, respectively.

The temperature difference between the inlet and outlet of the cold air and the hot air largely depends on the flow rate distribution, the inlet / outlet pressure ratio, and the inlet pressure of the compressed air, but can be obtained by the standard temperature difference obtained from FIG. 3 and the following equation.

Temperature difference = standard temperature difference × (absolute temperature at inlet / 293) For example, if the flow rate distribution between the high temperature side and the low temperature side is 50%, the pressure ratio is 2.7 and the inlet temperature is 40 ° C. 6 degrees C on the side and 74 degrees C on the high temperature side. Further, by changing the flow rate distribution to 80% for the high temperature side and 20% for the low temperature side, 0 ° C and 107 ° C can be obtained, respectively.

Various types of hot air and cold air obtained by this configuration can be used. For example, hot air can be introduced into the vehicle as it is, and can be directly used for heating the vehicle as clean warm air. The cool air may be used for cooling the inside of the vehicle, and the desired cooling can be quickly achieved even when the outside air temperature is high. That is, the heater and intercooler of the air conditioner can be simplified.

As described above, on the downstream side of the compressor 3 of the exhaust gas turbine supercharger 6, the Vortex cooler / heater 22 having the cylindrical chamber 21 and being supplied with the compressed air from the compressor 3 in the circumferential direction is provided. Since the hot air and the cold air of the predetermined temperature are generated, the compressed air can be effectively used for heating and cooling the inside of the vehicle, or lowering the supercharged air temperature, and can contribute to the simplification and downsizing of the air conditioner and the intercooler.

The vortex scooter / heater 22 has an extremely simple structure, can be easily applied to a conventional supercharged engine, and is highly versatile.

In the above embodiments, the exhaust gas turbine supercharger (turbocharger) is shown as a supercharger, but it is also applicable to other superchargers such as a mechanical drive type supercharger. It is possible.

On the downstream side of the compressor of the supercharger, a vortex cooler / heater that has a cylindrical chamber and that generates hot air and cold air by being supplied with the compressed air from the compressor in the circumferential direction is provided. With a simple structure, compressed air can be used for vehicle air conditioning, etc., which can contribute to simplification of air conditioning equipment.
