[0002] The parts of the automotive turbocharger system that use plastics mainly include the intake manifold and the connecting pipes of the intercooler. In the automotive turbocharger system, the application of plastic materials is mainly concentrated in the intake system and the cooling system. The intake manifold, as an important component of the turbocharger system, has a direct impact on the performance and efficiency of the system. The use of plastic intake manifolds is mainly due to their cost advantages, lightweight, and good thermal conductivity. Specifically, compared with aluminum intake manifolds9, plastic intake manifolds have the characteristics of low manufacturing cost, light weight, and good thermal conductivity.

The top of the outer shell 7 is plugged with an injection spark plug 24, and the bottom of the injection spark plug 24 is plugged with a carburetor 27. There are multiple tiny oil holes on the surface of the carburetor 27. The inside of the outer shell 7 is fixedly connected to a combustion tube 28, and the surface of the combustion tube 28 is designed with multiple air holes.

[0045] In this embodiment, gasoline enters the carburetor 27 through the oil guide pipe 23 and the fuel injection spark plug 24. The gasoline inside the carburetor 27 evaporates into the interior of the combustion tube 28 through the oil holes on the carburetor 27, starting the ignition function of the fuel injection spark plug 24, igniting the gasoline gas inside the combustion tube 28 to achieve ignition, and at the same time starting the motor 25 to drive the turbine 26 to rotate.

A large amount of air mixes with the gasoline gas inside the combustion tube 28 to cause explosion and generate huge pressure, which is ejected toward the rear of the rear shell 7, thereby achieving the effect of converting the chemical energy of the gasoline into mechanical energy.
[0046] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the compression mechanism includes two rotating impellers 31 fixedly connected to the other end of the rotating shaft 29, two fixed impellers 30 are fixedly connected to the inner wall of the outer casing 7 near the rotating impeller 31, and the other end of the outer casing 7 is fixedly connected to the exhaust cylinder 32, one end of the exhaust cylinder 32 is connected to the first exhaust pipe 9, one end of the exhaust cylinder 32 is connected to the second exhaust pipe 10 near the top of the first exhaust pipe 9, one end of the exhaust cylinder 32 is connected to the third exhaust pipe 11 near the top of the second exhaust pipe 10, one end of the exhaust cylinder 32 is connected to the fourth exhaust pipe 12 near the top of the third exhaust pipe 11, one end of the exhaust cylinder 32 is connected to the fifth exhaust pipe 13 near the top of the fourth exhaust pipe 12, and an auxiliary valve 18 is provided at the top of the fifth exhaust pipe 13.
[0047] In this embodiment, the gasoline gas inside the combustion tube 28 explodes and generates huge pressure to drive the two rotating impellers 31 at the rear end of the rotating shaft 29 to rotate. Due to the design of the fixed impeller 30, the direction of the high-pressure and high-temperature gas blows toward the rotating impeller 31, which is more conducive to the rotation of the rotating impeller 31, thereby improving the efficiency of the gas driving the rotating impeller 31 to rotate. The multi-blade design of the rotating impeller 31 can effectively compress the air. The rotation of the rotating impeller 31 drives the rotating shaft 29 to rotate, so that the turbine 26 continues to rotate, thereby realizing the explosion inside the combustion tube 28, driving the rotating impeller 31 to compress the air, and the rotating impeller 31 drives the turbine 26 to rotate and inhale air. The oxygen in the air allows the explosion inside the combustion tube 28 to continue to occur, realizing the circulating operation of the equipment and achieving the effect of compressing the air.
[0048] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4In a preferred embodiment, the oil circuit mechanism is fixedly connected to the oil tank 19 on the top upper surface of the first fixed plate 2. The upper surface of the oil tank 19 is designed with an oil inlet 20. A connecting pipe 21 is inserted into one side of the oil tank 19. An oil pump 22 is fixedly connected to the top upper surface of the first fixed plate 2 near the connecting pipe 21, and an oil guide pipe 23 is inserted into one side of the oil pump 22.
[0049] In this embodiment, the fuel tank 19 is filled with gasoline through the fuel inlet 20, and the fuel pump 22 is started to pump gasoline from the fuel tank 19. The gasoline flows into the oil guide pipe 23 through the connecting pipe 21 and the fuel pump 22 to achieve the fuel supply effect.
[0050] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the exhaust mechanism includes an exhaust groove 16 provided inside the sliding plate 6 near the silicone rubber tube 49, a buffer cylinder 15 is fixedly connected to one side edge of the exhaust groove 16, and a pressure valve 14 is provided at one end of the buffer cylinder 15.
[0051] In this embodiment, the used gas is discharged into the air through the air guide plate 38, the buffer cylinder 15 and the exhaust groove 16. In order to control the air pressure inside the air cavity 55, the speed at which the buffer cylinder 15 discharges the exhaust gas is controlled by rotating the pressure valve 14, thereby achieving the effect of controlling the gas pressure inside the air cavity 55.
[0052] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 6 In a preferred embodiment, the clamping mechanism includes a fixing frame 35 fixedly connected to one side of the second fixing plate 3, and the top of the fixing frame 35 is rotatably connected to the first clamping plate 36 and the second clamping plate 39, the top edge of the first clamping plate 36 is fixedly connected to a plurality of connecting blocks 43, and the two sides of the connecting block 43 are rotatably connected to the rotating clamping blocks 44, and the top edge of the second clamping plate 39 is fixedly connected to the fixed clamping block 45, and the top edges of the first clamping plate 36 and the second clamping plate 39 are respectively provided with a plurality of small grooves 42, and the outer walls on both sides of the first clamping plate 36 and the second clamping plate 39 are respectively provided with a plurality of medium-sized grooves 37, and the outer walls at the bottom of the first clamping plate 36 and the second clamping plate 39 are respectively provided with a plurality of large grooves 47.
[0053] In this embodiment, before and after the use of the device, the first clamping plate 36 and the second clamping plate 39 can be rotated and expanded to both sides respectively. By rotating the first clamping plate 36 and the second clamping plate 39 respectively, the outer wall of the silicone rubber tube 49 is clamped respectively, and the clamping block 44 is rotated and pressed so that the rotating clamping block 44 and the fixed clamping block 45 are clamped together, so that the first clamping plate 36 and the second clamping plate 39 clamp the silicone rubber tube 49, thereby fixing the silicone rubber tube 49.
[0054] It should be noted that the high-temperature and high-pressure air first enters the fifth exhaust pipe 13, and the high-temperature and high-pressure exhaust gas is discharged into the air through the action of the fifth exhaust pipe 13. After the combustion inside the combustion tube 28 is stably burned, the auxiliary valve 18 is gradually closed to allow the high-temperature and high-pressure exhaust gas to pass through the exhaust tube 32 and enter the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 respectively, to prevent the poor air flow inside the combustion tube 28 from causing the gasoline to be unable to burn stably. Since the lengths of the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are different, the area in contact with the air decreases successively, so that the gases discharged from the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are low-temperature and low-pressure gas, low-temperature and medium-pressure gas, medium-temperature and medium-pressure gas and high-temperature and high-pressure gas respectively, which has the effect of classifying the temperature and pressure of the gas.
[0055] Furthermore, these gases enter the multiple air cavities 55 between the silicone rubber tube 49 and the mounting column 48 through the air guide holes 46 on the air guide tube 33. Since the sizes of the small grooves 42, medium grooves 37 and large grooves 47 on the first clamping plate 36 and the second clamping plate 39 increase successively, the gases inside the multiple air cavities 55 continuously press the inner wall of the silicone rubber tube 49, forming bulges at the positions of the small grooves 42, medium grooves 37 and large grooves 47 respectively. If the bulges are slightly within the elastic range, the material is qualified. If the bulges are severely deformed or even broken, the material is unqualified. The low-temperature and low-pressure gas, the low-temperature and medium-pressure gas, the medium-temperature and medium-pressure gas and the high-temperature and high-pressure gas respectively simulate the gases generated by the automobile engine at different times, and verify the tear strength of the material used in the silicone rubber tube 49 under multiple temperature ranges and pressures.
[0056] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6In a preferred embodiment, the front-end sealing mechanism includes an air guide cylinder 33 fixedly connected to one side of the second fixed plate 3 near the position of the silicone rubber tube 49. A plurality of air guide holes 46 are designed inside the air guide cylinder 33. One end of the air guide cylinder 33 near the silicone rubber tube 49 is rotatably connected to the first front-end clamp 34 and the second front-end clamp 41 respectively. The tops of the first front-end clamp 34 and the second front-end clamp 41 are fixedly connected to clamping columns 54 respectively. A fixing block 40 is fixedly connected to the top of the clamping column 54 on one side of the second fixed plate 3. A threaded rod 52 is threadedly connected to one side of the fixing block 40, and an extrusion column 53 is fixedly connected to the bottom end of the threaded rod 52.
[0057] In this embodiment, the silicone rubber material used for the silicone rubber tube 49 is put on the mounting column 48, and the sliding plate 6 is pushed forward to slide so that one end of the mounting column 48 contacts one end of the air guide cylinder 33, and the first front end clamp 34 and the second front end clamp 41 are rotated respectively to clamp the front end of the silicone rubber tube 49. By rotating the threaded rod 52, the extrusion column 53 is moved downward to squeeze the clamping column 54, so that the first front end clamp 34 and the second front end clamp 41 continuously clamp the front end of the silicone rubber tube 49, thereby sealing the front end of the silicone rubber tube 49.
[0058] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In a preferred embodiment, the rear end sealing mechanism includes two sealing clamps 51 rotatably connected to the sliding plate 6 on one side close to the silicone rubber tube 49 , and the bottom end of the sealing clamp 51 is rotatably connected to a sealing ring 50 .
[0059] The other ends of the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are respectively inserted into the surface of the other side of the channel cylinder 17, and the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are respectively connected to the first exhaust port 57, the second exhaust port 58, the third exhaust port 59 and the fourth exhaust port 60, the other end of the connecting pipe 21 is connected to the oil pump 22, and the other end of the oil guide pipe 23 is connected to the injection spark plug 24.
[0060] The sizes of the small groove 42, the medium groove 37 and the large groove 47 increase successively. The first exhaust port 57, the second exhaust port 58, the third exhaust port 59 and the fourth exhaust port 60 are respectively connected to the multiple air guide holes 46. The extrusion column 53 and the clamping column 54 are used in combination. The material of the sealing ring 50 has a certain elasticity.
[0061] In this embodiment, the two sealing jaws 51 are rotated relative to each other to elastically deform the sealing ring 50, clamping the sealing ring 50 at one end of the silicone rubber tube 49. The sealing ring 50 is tightly clamped on the outer wall of the silicone rubber tube 49, thereby sealing the rear end of the silicone rubber tube 49.
[0062] Working principle: When in use, fill the fuel tank 19 with gasoline through the fuel inlet 20, start the fuel pump 22, and pump gasoline out of the fuel tank 19. The gasoline flows into the oil guide pipe 23 through the connecting pipe 21 and the fuel pump 22 to achieve the effect of fuel supply. The gasoline enters the carburetor 27 through the oil guide pipe 23 and the fuel injection spark plug 24. The gasoline inside the carburetor 27 evaporates into the combustion tube 28 through the oil hole on the carburetor 27, and the ignition function of the fuel injection spark plug 24 is started to ignite the gasoline gas inside the combustion tube 28 to achieve ignition. At the same time, the motor 25 is started to drive the turbine 26 to rotate. The special multi-blade design of the turbine 26 allows the turbine 26 to continuously inhale air while rotating at high speed. A large amount of air mixes with the gasoline gas inside the combustion tube 28 to cause explosion and generate huge pressure. The fuel is ejected toward the rear of the rear casing 7, achieving the effect of converting the chemical energy of gasoline into mechanical energy. The gasoline gas inside the combustion tube 28 explodes and generates huge pressure to drive the two rotating impellers 31 at the rear end of the rotating shaft 29 to rotate. Due to the design of the fixed impeller 30, the direction of the high-pressure and high-temperature gas blows toward the rotating impeller 31, which is more conducive to the rotation of the rotating impeller 31, thereby improving the efficiency of the combustion gas driving the rotating impeller 31 to rotate. The multi-blade design of the rotating impeller 31 can effectively compress the air. The rotation of the rotating impeller 31 drives the rotating shaft 29 to rotate, so that the turbine 26 continues to rotate, thereby achieving the explosion inside the combustion tube 28, driving the rotating impeller 31 to compress the air, and the rotating impeller 31 drives the turbine 26 to rotate and inhale the air, and the oxygen in the air makes The explosion inside the combustion tube 28 can continue to occur, realizing the circulating operation of the equipment and playing the role of compressing air. The high-temperature and high-pressure air first enters the fifth exhaust pipe 13, and the high-temperature and high-pressure exhaust gas is discharged into the air through the fifth exhaust pipe 13. After the combustion inside the combustion tube 28 is stably burned, the auxiliary valve 18 is gradually closed to allow the high-temperature and high-pressure exhaust gas to enter the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 through the exhaust pipe 32, so as to prevent the poor air flow inside the combustion tube 28 from causing the gasoline to burn stably. Since the lengths of the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are different, the area in contact with the air is reduced successively, so that the first exhaust pipe 9, the second exhaust pipe 10, the third exhaust pipe 11 and the fourth exhaust pipe 12 are 10. The gases discharged from the third exhaust pipe 11 and the fourth exhaust pipe 12 are low-temperature low-pressure gas, low-temperature medium-pressure gas, medium-temperature medium-pressure gas and high-temperature high-pressure gas, respectively, which have the effect of classifying the temperature and pressure of the gas. These gases enter the multiple air cavities 55 between the silicone rubber tube 49 and the mounting column 48 through the air guide holes 46 on the air guide cylinder 33. Since the sizes of the small grooves 42, medium grooves 37 and large grooves 47 on the first clamping plate 36 and the second clamping plate 39 increase successively, the gas inside the multiple air cavities 55 continuously presses the inner wall of the silicone rubber tube 49, forming bulges at the positions of the small grooves 42, medium grooves 37 and large grooves 47 respectively. If the bulges are slight and within the elastic range, the material is qualified. If the bulges are severely deformed or even broken,The material is unqualified. Low-temperature and low-pressure gas, low-temperature and medium-pressure gas, medium-temperature and medium-pressure gas, and high-temperature and high-pressure gas respectively simulate the gases generated by automobile engines at different times, and verify the tearing strength of the material used in the silicone rubber tube 49 under multiple temperature ranges and pressures. The used gas is discharged into the air through the air guide plate 38, the buffer cylinder 15 and the exhaust groove 16. In order to control the air pressure inside the air cavity 55, the speed of exhaust gas discharge from the buffer cylinder 15 is controlled by rotating the pressure valve 14 to achieve the effect of controlling the gas pressure inside the air cavity 55. Before and after the equipment is used, the first clamping plate 36 and the second clamping plate 39 can be rotated and expanded to both sides respectively. The silicone rubber material used in the silicone rubber tube 49 is put on the mounting column 48, and the two sealing clamps 51 are rotated relative to each other to elastically deform the sealing ring 50, and the sealing ring 50 is clamped on one end of the silicone rubber tube 49. The sealing ring 50 is tightly clamped on the outer wall of the silicone rubber tube 49, which has the effect of sealing the rear end of the silicone rubber tube 49. The sliding plate 6 is pushed forward to make one end of the mounting column 48 contact one end of the air guide cylinder 33. The first front end clamp 34 and the second front end clamp 41 are rotated respectively to clamp the front end of the silicone rubber tube 49. By rotating the threaded rod 52, the extrusion column 53 moves downward and squeezes the clamping column 54, so that the first front end clamp 34 and the second front end clamp 41 continuously clamp the front end of the silicone rubber tube 49, which has the effect of sealing the front end of the silicone rubber tube 49. By rotating the first clamping plate 36 and the second clamping plate 39 respectively to clamp the outer wall of the silicone rubber tube 49, the clamping block 44 is rotated and pressed so that the rotating clamping block 44 is clamped together with the fixed clamping block 45, so that the first clamping plate 36 and the second clamping plate 39 clamp the silicone rubber tube 49, thereby fixing the silicone rubber tube 49.
