Introduction of Oil Filter

If the engine is the "heart" of the truck, then the filter is the "kidney" of the car, the kidney in the human body plays the role of filtering blood, while the "kidney" of the truck filters the fuel.

The engine has air, oil, and fuel three kinds of filters, generally known as "three filters". They are responsible for the engine air intake system, lubrication system, and combustion system impurities in the filter.

Many people think that they use an engine filled with diesel, which has been a long time after the sedimentation, and through the three filters, so it is very clean, so the diesel filter on the diesel engine is dispensable.

Even if the diesel oil in the diesel tank before adding the sedimentation and filtration, is clean, in the refueling process, due to refueling tools, refueling environment, tank mouth unclean, and other factors will still make the diesel oil pollution, and in the the the the diesel engine running process, due to the impurities deposited in the fuel system, air suspended in the sink, will also make the diesel oil pollution, so the diesel filter on the car is essential, not to mention the diesel oil in Before adding to the tank is not necessarily really clean.

The Role of The Diesel Filter

The function of the fuel filter is to remove the debris from the diesel fuel and prevent the common rail system from clogging, especially the injector nozzles. It can effectively reduce wear and tear, ensure stable engine operation and improve the reliability of the engine.

The structure of the diesel filter is roughly the same as the oil filter, but its working pressure and oil temperature requirement are much lower than the oil filter, while its filtration efficiency requirement is much higher than the oil filter.

If the oil filter is damaged very seriously, then you can consider replacing it with a new one, for example, if you need a hh150-32430 oil filter, then you can buy the corresponding type of oil filter to replace it.

Types of Diesel Filters

Diesel filters are divided into detachable and spin-on types according to the installation form, and coarse and fine filters according to the usage.

At present, domestic diesel engines mostly use the paper diesel filter with a simple structure, small volume, small quality, good filtering effect, and low cost. The paper filter is mainly composed of the filter made of lv, the shell made of steel plate stamping, and the paper filter element.

The filter element mostly uses filter paper, in addition to filtering the mechanical impurities in diesel fuel, there is an important function is to filter water. The presence of water is very harmful to the diesel fuel supply system, rust, wear, jamming, and even deteriorating the combustion process of diesel fuel.

The way to remove water from the diesel filter system is mainly precipitation. Either set up a sedimentation chamber in the lower part of the filter or use a special sedimentation device. Both the lower sedimentation chamber of the filter and the special sedimentation device is equipped with a water release valve, when the water accumulates to a certain amount, open the valve and release the water. Also known as the oil-water separator filter.

Introduction of Oil-water Separator

An oil and water separator is a kind of fuel filter, the main role is to remove the water in the diesel fuel, in order to reduce the injector failure and extend the service life of the engine. The principle is mainly based on the density difference between water and fuel, the use of the gravity sedimentation principle to remove impurities, and the water separator, there are an internal diffusion cone, screen, and other separation components. The oil-water separator has other functions, such as pre-heating the fuel to prevent waxing, filtering impurities, etc.

Benefits of Installing Oil-Water Separation

If there is water or impurities inside the diesel fuel that is not filtered clean, it will cause strain on the plunger coupling inside the injector nozzle to form wear until the injector is stuck. Injector damage will cause engine acceleration instability or acceleration powerlessness, or emission of black smoke and other failures, affecting the normal operation of the vehicle.

As the first stage of the multi-stage filter system, the fuel coarse filter has the function of filtering out large particles of impurities and water. National standards for fuel pressure requirements, the water separation efficiency of the filter requires 95%, but many coarse filters do not achieve such a filtering effect, over time, it will cause damage to the engine.
