2. Description of the Related Art In an engine in which mechanical motion such as an internal combustion engine, a gear device and a bearing is carried out, a lubricating oil is used for the purpose of preventing friction and seizure between metal parts and promoting smooth motion. There is. As the lubrication method using this lubricating oil, at present, the pressure-feeding method in which the lubricating oil stored in the oil pan is sent to each part by pressure is the mainstream, and the oil that has finished lubrication in each part returns to the oil pan by gravity and is used again. Has been done. However, during the lubricating oil circulation process,
Dust and combustion products (in the case of internal combustion engine) in the intake process,
It is easy to mix in degradation products of additives caused by high temperature and high pressure, as well as fine metal powder due to wear of metal parts. For this reason, when such foreign matter is pumped again to each component together with the lubricating oil, the foreign matter adheres to the metal component, resulting in abrasion between the solid foreign matter and the components, poor lubrication, and burning between the components. Therefore, usually, a strainer element is provided to remove foreign matter mixed in the lubricating oil, thereby preventing friction and wear loss of the sliding surface or seizure of parts.

However, if the strainer element is designed to have a small passage area for foreign matter, clogging easily occurs, and it becomes impossible to supply lubricating oil to the bearing or sliding portion of the engine or the industrial machine.
It is currently designed to trap relatively large corrosion products. Therefore, it is usually designed to measure the hydraulic pressure difference between the inlet and outlet of the strainer element, and when this hydraulic pressure difference exceeds a certain value, the lubricating oil is designed not to pass through the strainer element but to be sent to each component such as the engine as it is. The strainer element is configured to be replaced in a cartridge system after being used for a certain period. Specifically, in a small generator engine, the strainer element is 5
It is instructed to replace it every 0 hours.

However, the replacement of the strainer element and the lubricating oil requires time and labor, and there is a problem that a large amount of waste lubricating oil and waste is generated by frequent replacement. . Furthermore, in the case of a diesel engine, the operating conditions are more severe than in a gasoline engine and the temperature tends to rise, so the deterioration of the lubricating oil is significant, and the soot and ash generated during combustion are high with particles of about 1 μm or less. Since it is often hard, it cannot be collected by the strainer element and is supplied to the engine and other parts as it is, causing the problem of wear and baking of parts. Therefore, in the industry, fine metal powder mixed in the circulation process and exhaust fine particles such as soot and ash due to combustion are suitably collected to prevent deterioration of the lubricating oil and supply high-purity lubricating oil to each engine. It has been desired to create a lubricating oil purifying apparatus that can be cleaned and can be reused as it is, without the need for replacement in a short period of time. (Note that the soot generated by combustion of a diesel engine is 1.0
A large amount of ~ 2.0 g / fuel 1 Kg penetrates the lubricating oil. )

As is clear from the results of Chemical Formulas 1 and 2, in the generator of the embodiment, the operating time until the total base number, which is the limit level causing corrosion and abrasion, is reached in the generator of the comparative example. It is about twice as much, and it can be seen that the deterioration of the lubricating oil is significantly prevented as compared with the generator of the comparative example, and the operation of the engine is not deteriorated even if the operating time is significantly extended. As is clear from the result of Chemical formula 3, the soot concentration in the lubricating oil of the generator of the example is significantly lower than that of the generator of the comparative example.
Therefore, it is said that the deterioration of diesel or other lubricating oil of an internal combustion engine is affected by the accumulation of soot in the lubricating oil, but in the embodiment, the soot concentration in the lubricating oil can be reduced, and therefore the deterioration is prevented. can do.
