Through Auto Diagnostic Tool checking data found paper air filter has the following advantages:
1) Filter efficiency up to 99.5% (oil bath air filter 98%), dust transmittance of only 0.1% -0.3%;
2) structure compact, can be installed in any orientation, not by vehicle parts layout constraints;
3) when maintenance is not consume fuel , but also save a lot of cotton yarn, blankets and metal materials and other substances;
4) the quality of small, low cost.
Based on the above advantages, car engines use air filter paper core is becoming more common. The key of good paper air filter is to keep its sealing performance, prevent unfiltered air from bypass entering the engine cylinder.
Paper air filter installation and maintenance guide
1. During installation, air filter and the engine intake pipe between rubber pipe coupling or direct coupling must be tight and reliable, to prevent leakage, the filter must be installed at both ends of the rubber gasket surface; fixed wing air filter housing nuts can not be tightened too much, so as not to crush paper filter.
2. In use, the air filter to prevent rain water paper, because once a large amount of water adsorbed paper, will greatly increase the intake resistance, shorten the service life.
3. Some vehicle engine is equipped with Tornado air filter, paper filter ends of the plastic cover is shroud cast blades rotating air, Launch X431 IV GX4 Master or Launch X431 V+ Pro3 tool data showed that: 80% of the dust separated by centrifugal force and collected in collection Dust arms, to dust paper filter for inhalation of dust was 20%, the total efficiency is about 99.7%.
4. During maintenance, paper filter never use oil cleaning, otherwise the paper filter will be failure, but also easily lead to accidents. When maintenance, use only the vibration method, soft brush division (which folds down to brush) or compressed air cleaning methods remove the attachment surface of the filter paper dust, dirt. Part of the strainer, should be promptly removed the dust parts, pipes, etc. of leaves and cyclone dust. Even if every time meticulously maintained, the paper filter can not completely restore the original performance, the intake resistance will increase, therefore, generally when the paper filter is required when the 4th maintenance, it should be replaced with a new air filter. If the paper filter rupture, perforation or unglued paper and cover other issues, should be replaced immediately.
Air filter is the air enters the engine from the first hurdle, automobile engine is very precise parts, the tiny impurities will damage the engine. Therefore, in the air into the cylinder before, must first go through the fine filtration of air filter, can enter the cylinder. You can use the Autel Maxidiag Elite MD701 or Autel MaxiTPMS TS601 tool regularly to check the engine, and the air filter status is related to the engine's life.
