Air Filter: useful information

Vehicles with internal combustion engines have an air filter that cleans the combustion air of unwanted fine aerosol particles, before it reaches the carburetor or the cylinders. Over time, the filter gets dirty, fact that may cause a variety of problems. First of all, the engine gets less air, which adversely affects its capacity. This, in turn, increases the fuel consumption. If the air filter is heavily soiled or clogged, it can cause serious problems.

Cleaning or replacing the air filter

You can avoid damages or unreasonably high fuel consumption by punctually cleaning or, if necessary, replacing the air filter. Which one of the two actions - replacement or cleaning – needs to be carried out, depends on the material of the filter. After a certain period of operation, which is determined by the manufacturer depending on the model, the air filter must be replaced. Cotton wool filters are treated with special oil and can be easily cleaned, even if they are heavily soiled. The price of such air filters is correspondingly higher. During the period when the car is under warranty, the air filter to replace has to be an original one (from the official vehicle manufacturer).

After this period expires, you can switch to more affordable (cheaper) air filters. Replacement of the filter is not of great complexity, and, as a rule, is very fast and easy to be done. Air filter can also be replaced or cleaned at any repair shop - for example, during the inspection or maintenance works.

Air Filter failures

  • the air filter is soiled;
  • the filter body is deformed;
  • the filter element is damaged.

Signs of air filter failures

  • engine noises and extraneous sounds are heard during running;
  • engine output is noticeably reduced;
  • engine start-up is difficult;
  • carbon monoxide content in exhaust is high;
  • the consumption of fuel is increased;
  • exhaust gases are black or gray.

Causes of air filter failures

  • Air Filter use beyond service life;
  • ingress of oil or water in the filter;
  • the car is often used in off-road conditions;
  • the part is installed incorrectly;
  • filter fixations are loosened;
  • hoses tightness is broken.

Diagnostics

To perform diagnostics without addressing to experts, it will be required to remove the filter from the case. Standard case fixations are snaps or screws. Having reached the filter, remove it and check its external condition.

It is necessary to check the degree of the filter impurity every 7000–8000 operational kilometers. If the part is soiled slightly, shake it out carefully and blow it. There should not be traces of water or oil on the filter surface. Otherwise it is necessary to check the radiator for damages.

Repair and replacement

It is necessary to change the air filter every 10000–15000 operational kilometers. Even if the filtering material is damaged slightly, the component is to be replaced immediately. If the filter damages are more essential, it is recommended to diagnose also cylinders and pistons of the engine. If dust appears into a compression chamber, the whole system of internal combustion can be broken down.

Air Filter replacement  is the least laborious car repair procedure. Even the inexperienced car owner can do it within 10 minutes. It is most expedient to replace the filter, for example, in the course of planned inspection of the engine and its cooling system.
