Description

Technical Field

[0001] This utility model relates to the technical field of teaching models for automotive fuel injectors, and in particular to a visual teaching miniature model of an automotive fuel injector with adjustable speed control. Background Technology

[0002] In automotive engineering education, the fuel injector, as a key component of the engine's fuel supply system, is the focus of teaching, and explaining its working principle and injection characteristics is a key teaching point.

[0003] However, current traditional teaching methods have many shortcomings. On the one hand, the combination of theoretical explanations and two-dimensional diagrams makes it difficult for students to intuitively understand the complex internal structure of fuel injectors and the dynamic fuel injection process; the abstract knowledge makes learning difficult for students. On the other hand, existing teaching models for automotive fuel injectors are mostly single-function, either lacking visualization design to allow students to clearly see the internal structure and fuel injection status, or unable to implement speed control, making it difficult to demonstrate the differences in the working conditions of fuel injectors under different operating conditions, which is not conducive to students' in-depth exploration of the performance changes of fuel injectors.

[0004] In view of the above problems, it is urgent to design a miniature teaching model of automotive fuel injectors with adjustable speed control and high visualization. It will effectively make up for the deficiencies of existing teaching tools and improve the quality and effect of teaching automotive fuel injectors. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a visually adjustable miniature model of a car fuel injector for teaching. By using a visual material for the outer shell of the fuel injector, its internal components can be seen, allowing students to intuitively understand the internal structure of the fuel injector during teaching. Furthermore, the speed control component enables the control of the fuel injection speed of the fuel injector, simulating the fuel injection state at the nozzle under different operating conditions of the car, thus effectively improving the quality of teaching.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A miniature teaching model of a visually adjustable automotive fuel injector, characterized by comprising a base plate, a housing, a fuel injection assembly, a fuel delivery assembly, and a speed control assembly. The housing is mounted on the base plate, a fuel injector support is provided on the housing, the fuel injection assembly is mounted on the fuel injector support, the fuel injection assembly is connected to the fuel delivery assembly, and the fuel delivery assembly is connected to the speed control assembly.

[0008] The fuel injection assembly consists of a fuel injector and a fuel injector controller. The fuel injector is mounted on a fuel injector support, and the injection port of each fuel injector is connected to the housing. The fuel injector controller is connected to the fuel injector via a wire and is mounted on the base plate.

[0009] The automotive fuel injector comprises a valve seat, a sleeve, a valve, an electromagnetic coil, a fuel filter, an electrical connector, and a spring assembly. The upper end of the valve seat is provided with a fuel filter, and the outer side of the fuel filter is provided with an electrical connector. The sleeve is installed inside the valve seat, and the valve is located below the sleeve. A spring is provided between the sleeve and the valve. An upper sealing ring is provided on the outer side of the fuel filter, and a lower sealing ring is provided at the lower end of the valve seat.

[0010] The speed control component consists of a voltage regulating power supply and an oil pump. The voltage regulating power supply and the oil pump are respectively mounted on the base plate. The voltage regulating power supply is connected to the oil pump and is connected to the automotive fuel injector controller through wires. By adjusting the voltage output of the voltage regulating power supply, the supply voltage to the oil pump is changed, thereby controlling the power of the motor inside the oil pump and dynamically adjusting the oil pumping rate.

[0011] The fuel delivery assembly includes a fuel tank, a fuel filter, a fuel rail, and a return fuel pump. The fuel tank and fuel filter are respectively mounted on the base plate. The fuel tank outlet is connected to the fuel pump inlet via a connecting pipe. The fuel pump outlet is connected to one end of the fuel filter via a connecting pipe.

The fuel pump delivers fuel from the fuel tank to the vehicle fuel injectors, and the return fuel pump recovers fuel injected into the fuel tank by the vehicle fuel injectors.

[0012] Furthermore, the enclosure is made of a transparent material, preferably acrylic sheet.

[0013] Furthermore, the valve seat is made of a transparent material, making it easy to observe the internal parts of the fuel injector.

[0014] The beneficial effects of this utility model are:

[0015] The automotive fuel injector used in the teaching model designed in this utility model has a valve seat made of a transparent material, and the housing is also made of a transparent material. This allows students to clearly and comprehensively observe the shape and layout of the various components inside the automotive fuel injector, as well as the real-time dynamic process of fuel injection. This makes abstract knowledge concrete, greatly reduces the difficulty of understanding for students, and facilitates their learning and comprehension.

[0016] The teaching model designed in this utility model adds a speed control component, which uses a voltage regulating power supply to control the oil pumping rate. This allows teachers or students to flexibly adjust the injection speed of the car's fuel injectors according to teaching needs, accurately simulating the working state of the fuel injectors under different operating conditions such as idling, acceleration, and high-speed driving. It intuitively shows the changes in injection characteristics, facilitates in-depth exploration of fuel injector performance, solves the problem that existing models cannot achieve speed control, and effectively promotes the improvement of teaching quality.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] As shown in the figure, a housing 2 is installed on a base plate 1. Multiple fuel injector support members 11 are installed on the housing 2, and each fuel injector support 11 is equipped with a fuel injector 8. The injection port of each fuel injector 8 is connected to the housing 2, allowing the fuel injector 8 to spray fuel into the housing 2. Furthermore, the inlet of each fuel injector 8 is connected to the outlet of the fuel rail 7 in the fuel delivery assembly. The housing 2 is made of a transparent material, preferably acrylic sheet.

[0025] like Figure 2 As shown, the automotive fuel injector 8 consists of a valve seat 14, a sleeve 20, a valve 16, an electromagnetic coil 15, a fuel filter 12, an electrical connector 13, and a spring. The upper end of the valve seat 14 is equipped with the fuel filter 12, and the outer side of the fuel filter 12 is equipped with the electrical connector 13. The electrical connector 13 is used to connect to the automotive fuel injector controller 9 via a wire. The sleeve 20 is installed inside the valve seat 14, and the valve 16 is located below the sleeve 20. A spring 17 is located between the sleeve 20 and the valve 16. An upper sealing ring 18 is provided on the outer side of the fuel filter 12, and a lower sealing ring 19 is provided at the lower end of the valve seat 14. The valve seat 14 is made of a visual material, allowing students to clearly and comprehensively observe the shape and layout of the various components inside the automotive fuel injector, as well as the real-time dynamic process of fuel injection. This visualizes abstract knowledge, greatly reduces the difficulty of student understanding, and facilitates student learning and comprehension.

[0026] The fuel tank 5 and fuel filter 6 in the fuel delivery assembly are respectively installed on the base plate 1. The fuel outlet of the fuel tank 5 is connected to the fuel inlet of the fuel pump 4 through a connecting pipe. The fuel outlet of the fuel pump 4 is connected to one end of the fuel filter 6 through a connecting pipe. The other end of the fuel filter 6 is connected to the fuel inlet of the fuel rail 7 through a connecting pipe. The fuel inlet of the loop fuel pump 10 is connected to the fuel outlet on the housing 2 through a pipe. The fuel outlet of the loop fuel pump 10 is connected to the fuel return port of the fuel tank 5 through a pipe. Therefore, the fuel pump 4 delivers the fuel in the fuel tank 5 to the fuel injector 8 of the vehicle, and the loop fuel pump 10 recovers the fuel injected into the housing 2 by the fuel injector 8 back to the fuel tank 5.

[0027] The voltage regulating power supply 3 and the oil pump 4 in the speed regulating assembly are respectively installed on the base plate 1. The voltage regulating power supply 3 is connected to the oil pump 4 and is also connected to the automotive fuel injector controller 9 through wires. The automotive fuel injector controller 9 is connected to each automotive fuel injector 8 through wires. The automotive fuel injector controller 9 is located on the base plate 1. Its function is to realize the timely opening and closing of the fuel injectors according to the engine power sequence and set time parameters to achieve the purpose of fuel injection. It also changes the power supply voltage of the oil pump 4 by adjusting the voltage output of the voltage regulating power supply 3, thereby controlling the power of the motor in the oil pump 4 and dynamically adjusting the oil pumping rate of the oil pump 4.

[0028] Furthermore, the connection method for mounting the housing 2 on the base plate 1 and the method for mounting the automotive fuel injector support 11 on the housing 2 are preferably fixed by magnetic connection. Alternatively, mortise and tenon structure or snap-fit ​​structure can be used to complete the mounting of the housing 2 on the base plate 1 and the mounting of the automotive fuel injector support 11 on the housing 2.

[0029] Furthermore, the number of oil outlets in the fuel rail 7 of the fuel delivery assembly is preferably set to 4. Of course, the number of oil outlets can also be 6, 8, 10, 12, etc., and these options can be set according to actual conditions, without specific limitations here. The fuel rail 7, also known as the fuel guide or fuel distributor, mainly functions to evenly distribute fuel to each of the vehicle's fuel injectors 8.

[0030] It should be noted that the voltage regulating power supply 3 and the oil pump 4 are both readily available equipment. The oil pump 4 is a pump with a voltage regulating knob, so the specific structure of these two components will not be described in detail.

[0031] Example 2

[0032] When the teaching model is being demonstrated, the oil pump 4 is started, and the fuel in the fuel tank 5 is precisely guided and delivered to each fuel injector 8 through the fuel rail 7. The fuel injector controller 9 controls the opening and closing of the fuel injectors 8 to perform fuel injection at the injection port. The fuel injected into the tank 2 by the fuel injectors 8 is sent back to the fuel tank 5 by the return oil pump 10 through the fuel outlet at the bottom of the tank 2.

[0033] By adjusting the voltage output of the voltage regulator 3, the power supply voltage to the oil pump 4 is changed, thereby controlling the power of the motor inside the oil pump 4 and dynamically adjusting the oil pumping rate of the oil pump 4. This allows for the control of the fuel injection speed of the car fuel injector 8, enabling teachers or students to flexibly adjust the fuel injection speed of the car fuel injector according to teaching needs. This accurately simulates the working state of the fuel injector under different operating conditions such as idling, acceleration, and high-speed driving, and intuitively demonstrates the changes in fuel injection characteristics.
