[0026] As described in the background section, during vehicle training, the structure of diesel engines cannot be fully and intuitively demonstrated, and students cannot intuitively and in detail understand the structure and fault locations of diesel engines. This results in low teaching quality of diesel engine construction principles and fault diagnosis, and poor training effectiveness.
[0027] Based on this, this application proposes a startable diesel engine testing and training bench to solve the problem of poor training results for diesel engines.
[0028] The present application will be described in detail below through one or more specific embodiments.
[0029] In some embodiments, this application provides a startable diesel engine testing training bench, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes:
[0030] The mobile platform 10 includes a placement compartment 11 and a mounting frame 12 connected to each other, wherein the mounting frame 12 is located outside the placement compartment 11;
[0031] The control and display panel 20 is located on the mounting bracket 12;
[0032] The diesel engine assembly 30 includes a diesel engine assembly 31, an instrument assembly 32, an engine electronic control system 33, an ignition switch 34, and a diagnostic interface 35 connected according to the actual vehicle. The diesel engine assembly 31 and the engine electronic control system 33 are both located in the storage compartment 11, and the instrument assembly 32, the ignition switch 34, and the diagnostic interface 35 are located on the control and display panel 20.
[0033] The fault setting system 40 is located between the diesel engine assembly 31 and the engine electronic control system 33. It sets a fault by controlling the disconnection of the components of the diesel engine assembly 31 from the engine electronic control system 33.
[0034] Specifically, the mobile test bench 10 includes two parts: a placement compartment 11 and a mounting frame 12. The mounting frame 12 is connected to the bottom side of the placement compartment 11 to install the control and display panel 20. The diesel engine assembly 31 and the engine electronic control system 33 are located inside the placement compartment 11 to be stably installed on the mobile test bench 10, preventing people from touching them and affecting their normal operation, which helps to improve the practicality of the testing and training test bench.
[0035] The diesel engine assembly 30 is connected according to the actual vehicle connection method to simulate the real starting and component connection of the diesel engine assembly 30, which is beneficial to the teaching quality. The instrument cluster 32, ignition switch 34, and diagnostic interface 35 are located on the control and display panel 20 for easy viewing and operation by the user, also simulating real settings and contributing to the teaching quality.
[0036] The diagnostic interface 35 can be connected to a dedicated or universal automotive decoder to perform self-diagnostic functions such as reading fault codes, clearing fault codes, and reading data streams on the engine electronic control system 33, so as to diagnose the faults of the diesel engine component 30 and improve the practicality of the testing training bench.
[0037] The fault setting system 40 can control the on / off status of various structures in the diesel engine assembly 31 and the engine electronic control system 33. When connected, the diesel engine assembly 31 operates normally without faults, and the fault setting system 40 is in an unset fault state. When disconnected, the diesel engine assembly 31 exhibits an abnormality and shows an operational fault, and the fault setting system 40 is in a set fault state. This enables the fault setting state of the testing training bench, allowing students to detect the fault and deepen their understanding of the structural principles of the diesel engine.
[0038] It should be noted that the diesel engine assembly 30 also includes a cooling system, a lubrication system, a starting system, a supply system, and an after-treatment system, and is connected in accordance with the actual vehicle connection method to ensure the structural integrity of the diesel engine assembly 30. This helps to deepen students' understanding of the diesel engine assembly 30 and improve the teaching quality.
[0039] In this embodiment, by setting the diesel engine assembly 30 and the control and display panel 20 on the mobile test bench 10, the diesel engine assembly 30 can be started on the mobile test bench 10, which facilitates observation of the starting and stationary states of the engine assembly. At the same time, the control and display module can view the instrument assembly 32, which is the same as the instrument interface of the actual vehicle, thus deepening the teaching impression. By setting the fault setting system 40, the testing training bench can be set to have faults in the diesel engine assembly 30, which facilitates guiding students to discover and detect the causes of faults in teaching, thereby deepening their understanding of the construction principle of diesel engines and their level of fault diagnosis, which is conducive to improving the teaching quality and effect.
[0040] In some embodiments, the fault setting system 40 includes a connected on / off switch and a potentiometer.
[0041] Specifically, fault settings are achieved by switching on and off the circuit breaker and by changing the current of the potentiometer.
[0042] For example, the diesel engine assembly 31's injectors, fuel metering unit, crankshaft and camshaft position sensors, intake air pressure and temperature sensors, fuel rail pressure sensors, coolant temperature sensors, fuel temperature sensors, oil pressure sensors, accelerator pedal 50 sensors, and the power control lines of the engine electronic control system 33 are all equipped with the fault setting system 40, so that the testing training bench can set multiple circuit breakage faults individually or simultaneously.
[0043] In some embodiments, the fault setting system 40 further includes a virtual button connected to the on / off switch and located on the control and display panel 20.
[0044] Specifically, the control and display panel 20 is provided with a fault setting panel, and the virtual button is located in the fault setting panel. The on / off state of the virtual button is controlled by the fault setting panel, thereby controlling the on / off state of the switch and realizing the start or stop of the fault setting system 40.
[0045] For example, there are multiple virtual buttons, each corresponding to a multiple on / off switch in the fault setting system 40. Each on / off switch corresponds to a fault. Therefore, the number of virtual buttons is the same as the number of faults that the fault setting system 40 can set. By operating one or more virtual buttons, one or more faults of the diesel engine assembly 31 can be set on the testing training bench.
[0046] In some embodiments, the control and display panel 20 is further provided with a plurality of detection terminals 21 for detecting the electrical signals of the pins of the various sensors, actuators and power control units of the diesel engine assembly 30.
[0047] Specifically, the detection terminal 21 is set on the control and display panel 20, which allows direct viewing of the electrical signals of each sensor, actuator, and power control unit pin, such as resistance, voltage, current, and frequency signals, on the control and display panel 20. This facilitates viewing during teaching and enhances the practicality of the detection training platform.
[0048] In some embodiments, the mounting bracket 12 is further provided with an accelerator pedal 50, which is connected to the diesel engine assembly 31.
[0049] Specifically, the accelerator pedal 50 can control the speed of the diesel engine assembly 31, which helps trainees understand the state of the diesel engine assembly 31 under different speed conditions and improves the teaching effect of the testing and training platform.
[0050] In some embodiments, the testing and training bench further includes a battery 60 and a charger 70, which are located on the mounting frame 12. The battery 60 supplies power to the control and display panel 20, the engine electronic control system 33, and the ignition switch 34, and the charger 70 is connected to the battery 60.
[0051] Specifically, the charger 70 is connected to the battery 60 to charge the battery 60. The battery 60 serves as the power source for the testing and training bench, providing power for starting the diesel engine assembly 31, powering the engine electronic control system 33, and powering the structures on the control and display panel 20. The arrangement of the battery 60 and the charger 70 allows the testing and training bench to operate independently, unaffected by power supply, and its position can be flexibly adjusted as needed, thus improving the practicality of the testing and training bench.
[0052] In some embodiments, the control and display panel 20 is provided with a charge / discharge switch 22 connected to the battery 60 and a main switch 23 connected to the battery 60.
[0053] Specifically, the charge / discharge switch 22 is used to control the operating state of the battery 60, that is, to control the battery 60 to switch between charging and discharging states. When the battery 60 is in the discharging state, the connection between the charger 70 and the battery 60 is turned off. When the battery 60 is in the charging state, the connection between the charger 70 and the battery 60 is turned on. Furthermore, the charge / discharge switch 22 can only operate when the main switch 23 is turned on.
[0054] In some embodiments, the bottom of the movable platform 10 is provided with universal self-locking wheels 13.
[0055] Specifically, four universal self-locking wheels 13 are provided at the bottom of the mobile platform 10, respectively located at the four corners of the bottom of the mobile platform 10. This allows the mobile platform 10 to move flexibly and can also be fixed, preventing the testing and training platform from moving randomly during use and improving the practicality of the testing and training platform.
[0056] In some embodiments, protective railings 14 are provided on the opposite side walls of the placement compartment 11.
[0057] Specifically, the diesel engine assembly 31 and the engine electronic control system 33 are placed in the storage compartment 11. The protective railing 14 can, to a certain extent, prevent external objects from contacting the diesel engine assembly 31 and the engine electronic control system 33, thus protecting the diesel engine assembly 31 and the engine electronic control system 33. On the other hand, the protective railing 14 can facilitate the user to move the testing and training platform, thereby improving the practicality of the testing and training platform.
