A Study of Lifetime of Air Cleaner Element for Vehicle in Bangkok and Suburban Area

Abstract

For an air filter, the major affect of good service work is the ability to removedirt and dust particles from air passing through it, in order to get the optimum air fuelratio and the air filter should be regularly checked. In this study, the air filter wasexamined under the real working condition which mainly in Bangkok and its suburbanarea. The amount of dirt and dust particles accumulated in the air filter element and theamount of air passing through it were measured every 1000 kilometers of operation.The results of the study reveal that with the given amount of the dirt and dust particlesaccumulated in the air filter element the amount of air passed through the fibrous airfilter is greater than of that passed through the paper air filter. It is also found thatwithout regularly cleaning of the filter element the fibrous filter should be changedwhen the vehicle operation reaches approximately 5000 kilometers. With regularlycleaning of the air filter element, it should be changed when the vehicle operationreaches approximately 7500 kilometers.
