いる。Generally, in a diesel engine, after the fuel oil in the fuel tank is processed by a predetermined processing device, it is temporarily stored in the engine service tank, and the fuel oil in the engine service tank is passed through a strainer by a supply pump. It is used to supply fuel to diesel engine fuel injection pumps, but in recent years,
The quality of fuel oil continues to deteriorate, resulting in higher specific gravity, higher viscosity, sludge,
It contains many impurities, including catalyst particles.

いればよい。First, the fuel oil introduced into the engine service tank is classified into high quality, medium quality, and low quality depending on the amount of sludge, impurities, and catalyst fragments.In the case of low quality fuel oil, the valve 15 is opened and the three-way valve 9 , 10 in the direction of each strainer 4, 5, 6 and operate the supply pump 11. As a result, the fuel oil in the engine service tank is passed through the supply pipe 12 to the first strainer 4. Most of the sludge, impurities, and catalyst fragments are filtered out.Then, the fuel oil passes through the second strainer 5.
After being filtered in the same way and further filtered by the third strainer 6, it is sent to the fuel injection pump 3 via the fuel pipe 18. In addition, in the case of medium fuel oil, the valve 16 is opened and the three-way valve 10 is connected to each strainer 5, 6.
The liquid may be passed in the direction of , and filtered through the second and third strainers 6 and 6. Furthermore, in the case of high quality fuel oil, the valve 17 may be opened and the fuel oil may be filtered through the third strainer 6. Note that in order to improve the fluidity of the fuel oil and to keep the viscosity constant at the inlet of the diesel engine 2, it is assumed that the fuel oil is heated. However, in the case of high viscosity oil, if the heating temperature becomes high, paper will form. Therefore, it is necessary to increase the supply power, and the fuel oil in the service tank is discharged to a pressure of 6 by the supply pump 11.
It is assumed that the fuel is supplied to the fuel injection pump 3 with a fin of ~10k9f. In the above embodiment, three strainers 4, 5, and 6 were used, but the invention is not limited to this; two strainers may be used when relatively high-quality fuel oil is used; When using oil, four or more may be used as necessary.

There are supply pipes that connect the container and the supply pump, and a fuel pipe that connects the downstream strainer and the fuel injection pump, so the fuel oil can be adjusted according to the quality of the fuel oil, from low to high quality. It can be filtered.
