For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Such as Figures 1 to 3As shown in the figure, the present invention provides an integrated detector for an electronically controlled engine, which includes: a display module 9, a detection module, a power control module, and a portable box. It is characterized in that the display module 9, the detection module, and the power control module are placed in the portable box, and both the detection module and the display module 9 are connected to the power control module. The detection module includes an analog temperature module 1, an analog intake pressure module 2, an analog speed module 3, and an analog fuel pressure module 4. The power control module includes power positive and negative terminals, a start terminal, a start button 11, a switch button 12, and an electromagnetic relay. A data interface 14 is also provided on the portable box, and the analog temperature module 1, the analog intake pressure module 2, the analog speed module 3, and the analog fuel pressure module 4 are all provided with the data interface 14.

[0032] The technical solution of the present invention simulates and couples phenomena such as temperature, intake pressure, speed, and fuel pressure when the vehicle starts through the analog temperature module 1, the analog intake pressure module 2, the analog speed module 3, and the analog fuel pressure module 4 in the detection module, measures the output of the electrical signal, and thus judges the working state of the electronically controlled device, achieving the purpose of quickly detecting faults. This integrated detector for an electronically controlled engine can ensure that the electronic control unit, sensors, and actuators are not damaged. Its operation is simple and fast, and there is no need to consider the problem of the connection circuit of the assembly components, effectively reducing the actual impact of the intersection between groups during the maintenance task.

[0033] The analog temperature module 1 is also connected to a temperature sensor 5, and the temperature sensor 5 uses a negative temperature coefficient thermistor. Specifically, in this embodiment, the temperature simulation module includes a liquid heating device, and the temperature change is realized through the liquid heating device, which can meet the measurement of the signal changes of the water temperature and oil temperature sensors.

[0034] The analog intake pressure module 2 is also connected to an intake pressure sensor 6. Specifically, in this embodiment, the strength of the wind speed at the air outlet of the fan is used to detect the change of the signal output through the intake pressure sensor 6.

[0035] The analog speed module 3 is also connected to a speed sensor 7. Specifically, in this embodiment, the installed position speed measurement device can realize the independent rotation of the signal wheel. Accordingly, position and speed sensors (including: crankshaft position sensor, camshaft position sensor, output and input shaft sensors, etc.) are installed on the fixed frame to detect the output and change of the electrical signal.

[0036] The analog fuel pressure module 4 is also connected to a fuel pressure sensor 8. Specifically, in this embodiment, the pressure generated by the pressure pump is used to simulate the change of the fuel pressure signal, thereby providing fast, efficient, and accurate detection parameters for maintenance operators.

[0037] The portable box also includes a system detection panel 15, wires and electronic components. The system detection panel 15 is used to fix the positive and negative power connection terminals, the start connection terminal, the start button 11, and the switch button 12.

The portable box also includes a bottom fixing panel, and the bottom fixing panel is used to place the electromagnetic relay. The portable box is made of plastic with light weight and strong anti-drop property. As Figure 3 shown, the power control module also includes a voltage converter 10.

[0038] As Figure 1 shown, the working principle of the electronic control engine comprehensive detector of the present invention is as follows:

[0039] The power control module sends instructions to the actuator. After receiving the instruction signal, the actuator changes the working state of individual systems of the engine, thereby changing the working condition of the engine;

[0040] The sensor receives the changed physical parameters and transmits them to the power control module through electrical signals;

[0041] The power control module makes a comparison and analysis based on the data stored inside, obtains corresponding instructions, and continues to send corresponding control and correction signals to the actuator.

[0042] When a certain electronic control component fails, the engine power control module will quickly protect the engine assembly and use the built-in program to achieve speed limit and torque limit for protection purposes.

[0043] When the maintenance task of the electronic control engine comprehensive detector of the present invention is in progress, it can effectively detect the electronic control system devices of the engine and the gearbox (which can simulate the physical changes when starting the vehicle) after the assembly components are disassembled, and can also detect whether the signal output is normal before installing new devices.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
