How to replace the filter element?

May 19, 2022

High-quality diesel filters can well protect the common rail system of diesel engines, thereby reducing maintenance costs. At the same time, in the process of use, the user needs to discharge water regularly, check regularly, and replace it in time to ensure the filtering effect of the filter. 


The use of advanced technology in the common rail system enables the engine to run smoothly and reduces fuel consumption and vehicle usage costs. Modern jet systems are so precise that their jet holes are too small to fit three hairs. Good filtration optimizes the quality of diesel in the injection system, resulting in longer system life and more mileage, so filters are an essential part of any diesel system.

In order to ensure the best performance of the engine, the filter must be checked and replaced regularly, please make sure to always use a high-quality filter, only such a filter can filter out moisture and the smallest impurities, so that the reliability of the engine is guaranteed.

One function of the filter is oil-water separation. Diesel fuels often contain small amounts of water, which can cause filter membrane blockage, injection system corrosion, and even freeze in winter. Because water is heavier than diesel fuel, water is blocked and flowed as pressurized fuel slowly passes through the filter. When checking or maintaining the engine, the water in the reservoir must be drained.

The diesel filter adopts a double filtration mechanism, which consists of several layers of filter paper with extremely small pores. The fuel is filtered when passing through the filter paper. When the diesel slowly flows through the filter, the high-quality filter can prevent any possibility. Particles that cause damage to the injection system, achieve a good filtering effect. Low-quality filters have poor internal sealing, which means impurities can pass through unhindered; high-quality filters have good internal sealing, and they prevent any unfiltered fuel from passing through and preventing it from entering the injection. system. A good filter also safely stores more particles.

High-quality filters last longer than low-quality filters. In addition, the filter needs to be checked and replaced regularly, once it is full of particles, the filtering function will fail, which will reduce the engine performance.
