If the filter is made of non-conforming filter media, it quickly becomes clogged and the engine “choking”. Pereobogaschennaya working mixture leads to increased fuel consumption and worsen the dynamic properties of the engine. For example, the minimum fuel consumption obtained with excess air for about 20%. Clogged filter can cause loss of power up to 10%. The feeling that the engine “does not pull” and is a symptom of the fact that it was time to change the air filter. It is worth paying attention to another extreme – this is where, despite the dusty road, that time would be in accordance with manufacturer’s recommendations? and change the filter, it does not lead to loss of power and can still work. Deceptive “efficiency” will result in sideways – “windfall” of engine failure.
The reasons may be three. The first – an unscrupulous manufacturer uses a filter paper or nonwoven fabric with a larger pore size through which the abrasive particles fly into the engine. Second – poor quality paper is torn and the engine also gets an overdose of dust. And the third – gapping filter raw air rushes into the engine, bypassing the filter element. That avoid unexpected problems should pay attention to the filter material, information on which bona fide filter manufacturers suggest. That material is defined as a filter to deal with this controversial task as an effective filtering and minimum power loss. Resource of 100,000 kilometers: fantasy or reality? Resource filters are the most common cars in Russia is 10-30 thousand? kilometers.
In dusty conditions of the Russian roads (or off-road) real? resource can be two to three times less. Conversely, in winter when the air is clean and fresh, the filter becomes clogged less. While domestic producers job of the production of air filters, which can withstand mezhservisny mileage of 10-30 thousand miles. However, the world’s automotive manufacturers in the new models are increasingly implementing the principle of a large mezhserivsnogo interval -? LSI (Large Service Interval). Air filters for a run at 10-30 thousand miles no longer fits the parameters of LSI. High mileage count? resource of 50 000 kilometers. It can not be achieved by using filters with a curtain of conventional cellulose which physically can not stand so long loads. Acceptable results in 50? 000 kilometers company Hollingsworth & Vose achieved through the use of technology Nanoweb (modified cellulose with a special coating), significantly which increases dust holding capacity filter elements. The material of tomorrow promises to be as corrugated synthetic variable density with an electrostatic charge, which provides a distance of 100 sq km. The principle of the “filter variable density “, made of materials” Hollingsvors “based on the fact that the outer layers of the material acts as a pre-filter. That air filters of new materials and the future belongs.
