How to use sinotruk howo air filter

HOWO Air filter can be said to be the unfamiliar truck accessories most familiar to card fans. As we all know, the air filter can purify the air entering the engine, so most card fans are very happy to replace the air filter in time, but the air filter is not replaced as often as possible.

Frequent replacement of the air filter, what problems will it cause to the engine, can the air filter be used for scrap and then replaced? Today, we will briefly discuss these issues with card friends.

The HOWO air filter, that is, the air filter, is composed of two parts: the filter element and the casing. The filter element is the main accessory, which plays the role of gas filtration, and the casing is the shell that provides protection for the filter element. The main function of the air filter is to filter the air entering the engine and purify the air quality.

The air contains a lot of impurities, such as dust, sand, etc. If it enters the engine chamber directly without purification treatment, it will accelerate the wear of the engine, and even cause the phenomenon of \"pulling the cylinder\". The air that enters the engine after being filtered by the air filter is relatively clean, which can delay the occurrence of these problems.

As a filter device, the air filter is inconspicuous compared to the sinotruk howo engine, gearbox and other accessories, but it has a very light status. Without being filtered by the air filter, the natural air directly enters the engine studio, which will cause the engine to wear out. If the air filter is not maintained for a long time, the filter element will be covered with dust, which will hinder the air circulation and make the engine work abnormally.

The air filter is seriously blocked, which will increase the air intake resistance, resulting in a decrease in the power of the engine. At the same time, due to the increase in air resistance, the fuel consumption of the engine will also increase, which will deteriorate the running state of the engine and increase the fuel consumption. Friends also need to maintain and maintain the filter element of the air filter.

Since the role of the air filter is so important, and if it is not maintained and maintained in time, it will also cause problems such as increased engine fuel consumption and reduced engine power, so can the filter element be replaced frequently? So that the engine can always be in the best working state? The answer is no.

In addition to filtering the air, the air filter is also responsible for the intake air volume required for the engine to work. Inferior filter elements, in order to reduce the cost, the quality of the materials used will be relatively poor, which will cause the air intake to be too large or too small, and even fail to achieve the filtering effect, which will directly lead to abnormal wear and tear of the engine.

So what about frequent replacement of standard air filters? In order to play a good filtering role in the air filter element, there will be a large number of irregular gaps on the surface of the filter paper, but dust, sand, etc. are also large and small, and it is impossible to become completely pure air after being filtered by the filter element. Contains some impurities.

In order to distinguish the filtration degree of the filter element, the concept of \"initial interception efficiency\" is introduced, which is usually expressed as a percentage (%). If the initial interception efficiency is 99.95%, it means that the filter element can filter out 99.95% of the impurities in the air during the initial operation, while 0.05% of the impurities cannot be filtered out, which will enter the engine with the filtered air.

Corresponding to the initial interception efficiency, there is also a \"full life efficiency\", which is also represented by a percentage (%). With the increase of use time of the filter, the dust accumulated on the surface of the filter paper will gradually increase, which will block some of the gaps between the fibers of the filter paper, which means that the pores between the fibers become smaller, and the interception efficiency of the filter element is compared with the initial state. Instead it rises.

So which interception efficiency is more advantageous, the initial interception efficiency and the full-life efficiency? Truck Home once conducted an experiment. The initial interception efficiency of a certain air filter can reach 99.81%, while its full-life efficiency can reach 99.98%. Comparing the two filtering effects, the difference is about 9.5 times.

That is to say, if the air entering the engine with a new air filter will contain 9.5 times more impurities than the air entering the engine with the old air filter. We have learned before that the increase in air impurities entering the engine will cause harm to the engine, so this is why the air filter element cannot be replaced frequently.

For the air filter, you can neither replace it frequently, always use a new air filter, or not replace it all the time, and the filtering effect cannot be achieved. So when is the best time to replace the air filter?

Under normal circumstances, the effective service life of the general air filter is about 20,000-30,000 kilometers, but depending on the actual operating conditions of the vehicle and the engine, the service life of the air filter will vary to some extent. This is mentioned in the maintenance manual. Card friends can choose to maintain or replace the air filter at the appropriate mileage according to their own conditions.

? Afterwords

Although the air filter is inconspicuous, its function is more important. It is not possible to replace the new filter element frequently, nor can it not be replaced all the time. When maintenance and replacement of the air filter, it is best to follow the manufacturer\'s maintenance manual. Execute, or maintain according to the advice of the repair station technician, so as not to cause immeasurable damage to the engine.
