The main function of the filter is to filter the particles, impurities and moisture that enter the engine system. It is one of the effective measures for users to change the filter protection, reduce the cost of equipment maintenance and prolong the service life of the system by reasonably choosing the filter of the high performance regular brand.

Harm of inferior filter:

The rated flow is not enough, which will cause the filter to overload for a long time and the service life is short.

The filter paper has large aperture, poor uniformity and low filtration efficiency, resulting in early wear of common rail system.

Water separation failure, common rail parts corrosion, adhesives are not oil, bonding is not strong, causing the filter short circuit, can not filter out impurities. Shorten the service life of common rail system.

The inner sealing ring of the filter is not oil resistant and the sealing is invalid. The short circuit can not filter out the impurity and cause the early wear of the common rail system.

Fuel filter heating and oil water separation, electrical joints, function failure and circuit damage, filter heating failure, low temperature, system performance and starting are affected.

The influence of the inferior filter on the engine is recessive and may not be detected immediately, but when the damage accumulates to a certain extent, it is too late to erupt.

The quality index of filter is not only the life of filter, but also the filter efficiency of filter. If the filter with low filter efficiency is used, it will not matter even if it is changed frequently. As the diesel contains water, do the routine filter maintenance at the same time, remember to use in the regular filter on the water.

Engine oils are constantly contaminated by metal filings, dust in the air, and carbon deposits. The heavy impurity deposits at the bottom of the oil pan, and lightly enters the friction surfaces with the lubricating oil, causing early wear of the parts. The function of the oil filter is to filter the lubricant through the filter. When the filter is used for a certain period of time, the filter will adhere to a lot of dirt, so it should be replaced regularly. In general, the oil filter and engine oil should be replaced at the same time. In this way, it is beneficial to prolong the service life of the engine.

Use the filter wrench or appropriate tools to remove the filter, to prevent damage to parts of the threaded connection. Check and clean oil filter mounting surface, otherwise, oil leakage is easy to occur after installation, resulting in insufficient oil supply. When installing the oil filter, apply a layer of oil on the surface of the sealing ring to ensure reliable sealing and prevent the sealing ring from being damaged.

Keep the filter clean, is any product should pay attention to, and now the filter more use paper filter core, shell is relatively hard plastic closed, belong to the consumables. Clogging in the filter leads to poor flow of oil, resulting in an increase in the oil temperature inside the filter. Therefore, we can observe the internal oil rise from the case to determine whether the filter is blocked.
