【Mrefilter】The quality of the common rail system and the diesel filter

Choose high-quality diesel filters to protect the common rail system

First of all, please make sure to choose a reliable gas station to fill with qualified fuel. The diesel filter is the last barrier to protect the fuel system. Compared with traditional fuel system technology, the common rail system is higher and more precise, and requires high-quality common rail system dedicated fuel filters. Please choose authorized or reliable channels to purchase and replace high-quality and qualified diesel filter elements, shch as Meiruier Filter. Do not use low-quality or counterfeit fuel filters to avoid damage to the system. The diesel filter needs to be inspected regularly, drained regularly and replaced regularly. The recommended replacement cycle of the diesel filter element is 10,000 kilometers.



The harm of inferior diesel filter

The hazards of inferior diesel filters to the diesel system mainly include the following 4 aspects:

1、The rated flow is insufficient and the filter is overloaded, which affects the dynamics of the vehicle and the service life of the fuel system.
2、The filter paper has large pore size, poor uniformity, small surface area, and low filtration efficiency, causing early wear of the fuel system and engine.
3、The oil-water separation fails, and the fuel components and the engine are corroded.
4、The internal bonding of the filter is not strong or the seal fails, which causes the filter element to be short-circuited, unable to filter out impurities, and causes wear of the fuel system and engine.


Tips for using diesel filter: prevent six misunderstandings

Misunderstanding 1：It does not matter what diesel filter is used, it does not affect the current operation.
Tips：The impact of inferior filters on the fuel system and engine is hidden and may not be discovered immediately, but it will be too late when the damage accumulates to a certain extent.

Misunderstanding 2：The quality of the diesel filter is almost okay, there is no problem if you change it frequently
Tips：A measure of filter quality is not only the life of the filter, but more importantly the filter efficiency of the filter. If a filter with low filtration efficiency is used, the fuel system cannot be effectively protected even if it is replaced frequently.

Misunderstanding 3：The filter that does not have to be changed frequently is definitely the best filter
Tips：Sometimes high-quality filters will be replaced more frequently because they can filter out impurities more effectively.

Misunderstanding 4：As long as the diesel filter is replaced regularly
Tips：Diesel oil contains water. When the filter is replaced regularly, remember to check the filter regularly and drain the water regularly.

Misunderstanding 5：It is important to change the oil and filter regularly, but it is not so important to drain the diesel filter regularly.
Tips：If the diesel filter is not regularly drained and replaced regularly, it will also cause damage to the fuel system and engine. It is recommended to check and release the water regularly and replace it every 10,000 kilometers.

Misunderstanding 6：The high-quality diesel filter is more expensive. During the warranty period, the cheap filter can be used even if it fails.
Tips：The manufacturer has the right to refuse to pay for damage caused by the user's improper use. The price of fuel system or engine maintenance is often dozens of times or even higher than the price of high-quality filters. It is unwise to use inferior filters, whether in or out of warranty.
