Thread: Air filters for passenger cars

 
Incorrectly say that in winter the air is clean and fresh, and the air filter for the engine of a car is not required. Just look at all the trash that will have time to accumulate in the spring to ensure the opposite. And therefore, to choose an air filter for your car you want with all the care and skill.



First of all you need to know that air filters for cars classified as liquid and dry. The last use special cartridges that need to be replaced after a certain number of kilometers. "Wet" air filters have in their construction a special tank, which is filled with simple mineral oil. The air coming through the inlet filter, is reflected from oil and continues to go to the inlet manifold of the engine. But the situation is complicated by the fact that in the winter of mineral oil tends to thicken and it begins to lose its properties on the delay of the abrasive particles, which are in abundance there is in the air.



That is why, now in the course of the so-called "dry" air filters in which a filter element is a special cardboard, through which passes the air.

All "dry" air filters are divided among themselves - how they can create resistance to the incoming air. Sport models use the so-called filters zero resistance or more olevik, through which the cleaned air is suitable for input to the collector without any resistance!



But, nevertheless, even "simple" air filters using cardboard cartridges, which can deliver maximum efficiency to clean the incoming air. In the best filters of this type the ratio of purification is an impressive figure - 99.4!



Applying filters for special form, the cartridge is allowed to collect filters of all sizes and shapes. Previously, liquid filters, applied design exceptional round type, but now there's a rare opportunity for manufacturers to design and build filters of any configuration - from round to rectangular.



This allows them to use up to a maximum of: cartridge element can be used every 20 000 km!
To prevent the passage of untreated air into the engine, most of the manufacturers use such insulating material, which is called plastisol. This material is an excellent sealant between cardboard cartridges and plastic filter housing.

As a result, completely eliminates the ingestion dirty ambient air, which can significantly extend the life of any engine from petrol to diesel.
