Air Filter. whatnot, that drivers forget

Air Filter

The air filter is so trivial part that is often forgotten when a service the car. Although it costs a lot and his replacement takes a few minutes, it plays a very important function, direct impact on the durability of the engine.

The air dust in an amount of about 0.0001 do 0.0003 g / m³. When the car is used outside of paved roads, dust level is very high, can reach up to 0,005 g / m³. Therefore, it is assumed that the car “inhalation” the air from the dust content of about 1 mg / m³, and this leads to after traveling from 1000 km to the suction system reaches several tens of grams of sand, because that is what the dust. To bi prelazilo kroz ulazni kolektor i unutrašnjost motora, a i turbocharger, that there is no air filter.

This is a trivial element, but his role is essentially important. Today's air filters are designed to keep around 98-99 percent of dust. It would be easy, the engine does not need to breathe, especially turbocharger. Therefore, the filter can not hold too much air, which causes some compromise in bandwidth. There are optimum flow of air from filter 2 mikrometara.

Air Filter

Modern passenger vehicles are equipped with dry air filters, typically with a paper or a textile inlay, arranged in the so-called harmonica, which makes the filter surface area much greater than the diameter. Accordion create a dense network, which stops dirt, a total inlet to the filter systems are designed so that the air still enters the filter from the bottom. Thanks to that, filtering the box, dust stops below, and when it collects too, it falls and is collected in the filter chamber. This effect can not always get, na primer, the filter drum or ring, why not use. Aside from, complete systems for air intake filter with many turns, “detours”, curve and narrowing, so that the air entering the filter partly soothes, its speed is reduced (less noise) and partly the net.

Dry filters are used since the 1960s, but still in working machines, as well as in off-road vehicles operating in very difficult conditions, used oil filters air. The idea is that the air enters the filter in such a way that will cause a strong vortex and more will be cleaned larger dust particles. Aside from, Filter cartridges are soaked in oil which retains the dirt. This filter works perfectly where the amount of dust soaring. The advantage of oil filters is a small air resistance with very good cleaning dust, but the lack of a short life span. Another thing is that these types of filters should only be washed and re-saturate oil.

Basically, service air filter is reduced to the periodic replacement and cleaning chamber which houses. Both activities are important, because cleaning extends the life of the filter. Normalno, manufacturers recommend replacement every 30-60 one thousand kilometers and as always are very optimistic courses. Some raise the limit on 80.000 km. Actually, filter loses properties after only 20.000 km. Do not clean (beating, compressed air) air filter, which may cause dirt to enter the clean side of the filter. However, it is best to replace the filter because prices are not high, a zamenu će obavljati gotovo svako. Before installing the new filter, worth the suction bucket / box in which the air filter is installed. It is necessary to pay attention to the sealed closure of the filter chamber, it will be sucked air is not filtered.

Dirty air filter first causes a decrease in strength, implying a greater effort turbocharger or increase in fuel consumption. Aside from, affect the characteristics of the engine, motor slabije reaguje na dodavanje gasa. Zato je vredno zameniti ga na ne više od 20000 km, or preferably, as proposed by experienced technicians at each oil change.
