The first outlet of the tee connector is connected to the engine oil pump via a lubrication line, and the second outlet of the tee connector is connected to the electric motor oil pump 29 via a lubrication line. The engine oil pump and the electric motor oil pump 29 form two lubrication lines to supply oil for lubrication of the engine 1. The electric motor oil pump 29 is used for pre-lubrication before the engine 1 is started, and the engine oil pump is used for oil supply lubrication after the engine is started. The engine return oil pump is used to recover the lubricating oil to the lubricating oil tank 28 after the engine is stopped.

[0034] In some alternative embodiments: see Figure 1 , Figure 2 and Figure 6As shown in the figure, this application embodiment provides an integrated maintenance device for off-vehicle engines. The integrated maintenance device has a radiator 23 with an inlet 231 at the bottom and an outlet 232 at the top. A cooling fan 233 is connected to the radiator 23. A sensor for detecting the coolant temperature is connected to the radiator 23. The cooling fan 233 and the sensor are connected to a controller 234, which controls the operating power of the cooling fan 233 based on the coolant temperature detected by the sensor.

[0035] In this embodiment, the radiator 23 has an inlet 231 at the bottom and an outlet 232 at the top. The inlet 231 and outlet 232 are connected to the cylinder block water jacket of the engine 1 via water pipes, forming a closed-loop cooling water circuit.

[0036] In some alternative embodiments: see Figure 1 and Figure 2 As shown in the figure, this application embodiment provides an integrated maintenance device for off-vehicle engines. The air outlet of the air tank 24 of this integrated maintenance device is connected to a starter air distributor (not shown in the figure) via a high-pressure air pipe. The starter air distributor is used to start the engine 1. The air tank 24 stores compressed air at 15 MPa. When the engine 1 needs to be started, the air tank 24 supplies compressed air to the starter air distributor. The compressed air distributed by the starter air distributor enters the cylinder of the engine 1 to drive the engine 1 to complete the starting action.

[0037] The integrated maintenance device also includes a battery pack 30 fixed to the support frame 11. The battery pack 30 is a 24V lithium battery with a capacity of 15Ah.

The fuel supply assembly 21, the oil supply assembly 22, and the radiator 23 are all equipped with piping fittings for connecting to the engine 1. These piping fittings can be configured according to different types of engines, expanding their application range.

[0038] See Figure 7 As shown, when inspecting the engine 1 after it leaves the vehicle: first, lift the engine 1 from the vehicle body position to the horizontal ground and fix it with square timber or brackets. Then, move the integrated inspection device to the side of the engine 1 and lock the travel casters 12.

[0039] Select the appropriate piping fittings for the model of engine 1, connect the piping fittings to the corresponding interface between the integrated maintenance unit and engine 1, and tighten them with clamps. Check the fuel level in the fuel tank 25, the lubricating oil level in the lubricating oil tank 28, and the gas pressure in the gas storage tank 24 in the integrated maintenance device, and add coolant to the radiator 23 through the inlet or outlet pipe.

[0040] A steel wire rope is connected to the oil filling lever 2 on the high-pressure diesel pump of engine 1, so that the operator can control the throttle and turn on the switch of the electric motor oil pump 29 to pre-lubricate engine 1.

[0041] Open the vent bolt 3 on the filter and the high-pressure diesel pump, and turn on the fuel distribution switch 26 and the fuel supply pump set 27 to vent the diesel fuel line.

[0042] Pull the steel cable on the connecting refueling lever 2 to the maximum refueling position, open the valve of the air tank 24, and immediately close the valve of the air tank 24 after the engine 1 starts. At the same time, loosen the steel cable to reduce the throttle opening.

[0043] After the test run is completed, completely loosen the wire rope, shut off the oil supply, disconnect the pipelines and fittings of the engine 1 and the integrated maintenance device, drain the residual oil and water from the pipelines, and remove the pipelines, fittings and the integrated maintenance device.
