[0047] In the embodiment, as shown in Figure 1 and Figure 16 The outer end inner wall of the air inlet shell 210 is rotatably connected with a cylindrical rotary frame 250, the inner end wall of the cylindrical rotary frame 250 is fixedly installed with a plug cover 251, and the plug cover 251 is clamped with the circular exhaust port 216, the outer end wall of the cylindrical rotary frame 250 is rotatably connected with an electric push rod 252, and the electric push rod 252 is fixedly connected with the side wall of the supercharging shell 111, when the electric push rod 252 is driven, the plug cover 251 is forced to plug the circular exhaust port 216, the exhaust gas in the supercharging channel 222 will only be discharged through the exhaust hole 221, so as to force the exhaust turbine 123 to rotate.

[0048] In the embodiment, as shown in Figure 17 and Figure 18As shown, the inner wall of the air inlet shell 210 is sealingly and fixedly connected with an air inlet inner shell 220, the air turbine 123 is located in the air inlet inner shell 220, the side wall of the air inlet inner shell 220 is provided with an exhaust hole 221, and the exhaust hole 221 is in communication with the air turbine 123, the air turbine 123 is in movable contact with the inner wall of the air inlet inner shell 220, the air inlet inner shell 220 and the inner wall of the air inlet shell 210 are provided with a pressurizing channel 222, and the exhaust gas can be discharged through the exhaust hole 221 after the pressurizing effect of the pressurizing channel 222, so that the air turbine 123 rotates, the cross-sectional area of the pressurizing channel 222 changes from large to small, the first end of the pressurizing channel 222 is in communication with the air inlet channel 211, and the exhaust hole 221 is in communication with the last end of the pressurizing channel 222, the end wall of the air inlet shell 210 is sealingly and fixedly connected with an air inlet bottom shell 230, and the side wall of the air inlet bottom shell 230 is fixedly connected with the end wall of the pressurizing bottom shell 116, in the application, when the automobile moves at high speed, i.e. the engine works at high power, the electric push rod 252 is driven to force the plug cover 251 to plug the circular exhaust port 216, at this time, the exhaust gas in the pressurizing channel 222 will be discharged through the exhaust hole 221, and since the cross-sectional area of the pressurizing channel 222 changes from large to small, the pressure of the exhaust gas will gradually increase when passing through the pressurizing channel 222, and reaches the maximum when being discharged through the exhaust hole 221, at this time, the exhaust gas can drive the air turbine 123 to rotate, and through the guide effect of the rotating shaft 120, the air turbine 122 can be driven to rotate at the same speed.

[0049] The working principle of the technical scheme provided by the application is as follows: when the automobile moves at low speed, i.e. the engine does not need to work at high power, the exhaust gas generated by the automobile will enter the pressurizing channel 222 through the air inlet channel 211, at this time, the outer push cylindrical rotating frame 250 is pushed out by driving the electric push rod 252, so that the cylindrical rotating frame 250 rotates, the plug cover 251 is separated from the circular exhaust port 216, and at the same time, the air baffle blade 213 is deflected by driving the stepper motor 214 through the potentiometer 215, so that the cross-sectional area of the square channel port 212 reaches the maximum, at this time, the exhaust gas in the pressurizing channel 222 will be directly discharged through the circular exhaust port 216, so that the air turbine 123 cannot drive the rotating shaft 120 to rotate.

[0050] When the car is moving at high speed, i.e. the engine is working at high power, the electric push rod 252 is driven to force the plug cover 251 to plug the circular exhaust port 216. At this time, the exhaust gas in the supercharging passage 222 will be discharged through the exhaust hole 221. Since the cross-sectional area of the supercharging passage 222 changes from large to small, the pressure of the exhaust gas will gradually increase when passing through the supercharging passage 222, and reach the maximum when being discharged through the exhaust hole 221. At this time, the exhaust turbine 123 can be driven to rotate, and through the guide effect of the rotating shaft 120, the air turbine 122 can be driven to rotate at the same speed. At this time, the air turbine 122 can generate negative pressure in the supercharging inner shell 113, so as to suck the external air. Through the guide effect of the air turbine 122 and the guide vane 134, the sucked air is discharged into the decompression passage 115 through the semi-spiral groove 114. Since the cross-sectional area of the decompression passage 115 changes from small to large, the pressure of the air will gradually decrease when passing through the decompression passage 115, and reach the minimum at the exhaust passage 112. Thereafter, the air is discharged into the engine through the exhaust passage 112 for use. In this process, the greater the power of the engine, the more exhaust gas is generated, i.e. the greater the pressure of the exhaust gas discharged through the exhaust hole 221, the faster the rotating speed of the exhaust turbine 123, and the greater the pressure of the exhaust gas discharged by the exhaust turbine 123, the more exhaust gas enters the exhaust pipe 240, i.e. the greater the pressure generated in the sealing cylinder 136, the greater the deformation of the elastic sealing film 140. Under the guide effect of the cylinder groove 137, the elastic sealing film 140 can drive the sliding cylinder 141 to move downward, so that the push column 142 drives the guide frame 139 to move downward, forcing the guide plate 138 to drive the L-shaped rod 135 to rotate, so that the rotating ring 131 rotates, the connecting plate 132 drives the rotating column 133 to rotate, the guide vane 134 on the end wall of the rotating column 133 rotates, the included angle between the guide vane 134 and the first end of the semi-spiral groove 114 increases, and the air entering the decompression passage 115 increases, so that the air discharged into the engine increases, and the combustion is more complete.

[0051] When the car is accelerating, the electric push rod 252 is driven to force the plug cover 251 to separate from the circular exhaust port 216. At the same time, the stepper motor 214 is driven through the potentiometer 215 to make the air deflector 213 deflect, so that the cross-sectional area of the square passage 212 gradually decreases. At this time, the pressure of the exhaust gas discharged through the exhaust hole 221 gradually increases. In summary, the air entering the decompression passage 115 gradually increases, and the air discharged into the engine gradually increases. Conversely, when the car is decelerating, the cross-sectional area of the square passage 212 gradually increases, so that the balance between low-speed torque and high-speed efficiency can be achieved.
