Engine cleaning, engine oil draining and engine oil filling can optionally be performed. Hereinafter, a description will be given of the operation and usage of the device for these operations by taking the case of serving the gasoline engine 20 as an example.

[Engine cleaning work]

When cleaning the gasoline engine 20, as shown in FIG. 3, the oil inlet 23 of the upper part of the engine 20 is opened and the cleaning liquid is injected without discharging the engine oil inside the engine 20. . In addition, after removing the oil filter 22 of the engine 20, the coupling member 120 is mounted on the oil filter mounting part 21 of the engine, and then the first switching valve 141 is switched to the cleaning mode so that the oil circulation pipe ( 134 and the oil supply pipe 133 downstream of the first switching valve 141 communicate with each other.

When the engine 20 is operated in this state, the oil inside the engine 20 circulates through the cleaning filter 142 by an oil pump (not shown) operation inside the engine. At this time, the inside of the engine 20 is washed by the action of the cleaning liquid, and impurities included in the engine oil are filtered while passing through the cleaning filter 142. The cleaning operation maintains this state for a predetermined time. After the cleaning is finished, a discharge operation for forcibly discharging the engine oil inside the engine 20 is performed.

[Engine oil discharge operation]

After the cleaning operation, as shown in FIG. 4, the oil discharge port 24 under the engine 20 is opened to discharge the engine oil. At the same time, the air flow path switching valve 310 is operated to allow the compressed air to flow into the first compressed air engine 135 for gasoline from the compressed air source 40, and the first switching valve 141 and the second switching valve 143. ) To the oil filling mode. In this case, the oil supply pipes (131, 132, 133) are communicated from the oil tank 110 to the connecting member 120, and compressed air is injected into the oil tank 110, so that the new engine oil inside the oil tank 110 is a predetermined amount of engine ( 20). Therefore, the waste engine oil inside the engine 20 is discharged to the oil outlet 24 while being diluted by the newly injected engine oil, thereby improving the cleaning effect of the engine 20.

After injecting new engine oil for a predetermined time, as shown in FIG. 5, the second switching valve 143 is switched to the air injection mode. In this way, the injection of new engine oil to the engine 20 is blocked, and the compressed air of the first compressed air engine 135 is supplied with the oil supply pipe 132 downstream from the second compressed air engine 136 and the second switching valve 143. It is injected into the engine 20 through the). Therefore, the remaining engine oil inside the engine 20 is forcibly discharged to the oil outlet 24 by the compressed air injected.

When the engine oil is discharged by injecting the compressed air as described above, since the remaining engine oil inside the engine including the cleaning liquid can be almost completely discharged, damage to the engine 20 that may occur due to the cleaning liquid can be minimized. .

[Engine oil injection work]

Injection of the new engine oil is performed after completing the above-described engine oil discharge operation. When injecting the engine oil, as shown in FIG. 6, first, the amount of remaining engine oil in the oil tank 110 is checked through the transparent liquid pipe 115, and when insufficient, the engine oil is replenished in the oil tank 110. Then, the amount of engine oil to be injected is set by moving the oil injection amount setting member 116. In this state, the air flow path switching valve 310 is operated to allow the compressed air to flow into the first compressed air engine 135 for gasoline from the compressed air supply source 40, and the first switching valve 141 and the second switching valve. Switch (143) to oil injection mode.

In this case, the oil supply pipes 131, 132, and 133 communicate with each other from the oil tank 110 to the connection member 120, and compressed air is injected into the oil tank 110, so that a new engine oil inside the oil tank 110 is provided. Is injected into the engine. When the engine oil is injected, the user looks at the transparent liquid pipe 115 to allow the engine oil of the oil tank 110 to be injected to the position of the oil injection amount setting member 116, and then finishes the injection of the engine oil. Then, the connection member 120 is separated from the engine 20, and a new oil filter is mounted on the oil filter mounting part 21 of the engine 20.

As described above, since the present invention can perform the engine cleaning operation, the engine oil discharge operation, and the engine oil injection operation in succession through one device, the operations from the cleaning of the engine to the injection operation of the engine oil can be performed quickly. Can be. Here, the case of performing these operations in succession has been described, but the present invention may selectively perform these operations through the operation of the first and second switching valve.

In the case of the diesel engine 30 can be serviced in the same manner as above using the equipment for diesel (200). Of course, in this case, the air flow path switching valve 310 is operated in a diesel mode so that the compressed air supplied from the third compression air engine 300 is supplied to the first compression air engine 235 for diesel.

Figure 7 shows an example of using the device according to the invention in a different way for the injection of engine oil. As shown in FIG. 7, the oil is injected in a state in which a separate oil injection connecting member 160 connected to the oil supply pipe 133 is connected to the oil inlet 23 of the engine 20. This operation may be performed in the same manner in the gasoline equipment 100 and the diesel equipment 200.

In this case, the air pressure regulating device 420 may be installed in the first compression air pipe 435 and the system may be configured in a state in which the air flow path switching valve 320 mentioned in the first embodiment is excluded. The other configuration is substantially the same as the equipment for gasoline of the first embodiment. In the second embodiment, since the oil tank 410 and the cleaning filter 442 are one, it is preferable to use the gasoline engine or the diesel engine only.
