Dust filter function is to filter out suspended particles in the air entering the cylinder to reduce the cylinder and the piston and piston ring wear. Three kinds of engine medium required, the maximum amount of air, and from the atmosphere. If the air filter can effectively filter out suspended particles in the air, the light speed cylinder, piston and piston ring wear, heavy cylinder will cause injury and shorten engine life. 1, using Myth # 1) purchase without seeking quality. As part of the maintenance staff did not correctly understand the importance of the air cleaner when you buy only cheaper, not for quality, so that the engine will be equipped with abnormal shortly. Especially the auto market of fake and shoddy products more cases, the purchase should shop around, insist on quality first principle. 2) the use of arbitrarily removed. Engine air filter must be scientifically based. However, some people have above drivers remove the air filter, directly sucked into the engine without an air filter. Remove the air filter on the truck's tests showed: Remove the air filter, the engine cylinder wear surge eight times, piston wear surge three times, and piston ring wear increased nine-fold. 3) Maintenance and replacement are not from reality. Truck "User Manual", which provides that in mileage or working hours as the data for maintenance or replacement. But in fact air filter maintenance and replacement cycle is also related to environmental factors. Often traveling at more than the amount of dust in the environment where the air filter maintenance or replacement cycle should be shorter; less in dusty environments, air filter maintenance or replacement cycle can be extended. In practice, many people drive mechanically repair work required, rather than according to environmental factors such as different flexibility, mileage standards have to wait until the engine has been significantly abnormal operating state only for maintenance. Notes, and then maintained at this time, not only has caused irreparable damage, but also cause more damage to the engine. What is more, the individual drivers do not know the air filter will fail, as long as the outside is not damaged to continue to be used. 2, the identification method to working conditions the air filter, when maintenance or replacement, be identified according to the following method: In theory, the air filter life and the maintenance interval of the filter element should be a stream gas flow rate and the desired engine The ratio of the gas flow to be measured. When the flow rate is greater than the flow, the filter is working properly; when the flow rate is equal to flow, the filter should be maintained; when the flow rate is less than the flow rate, the filter can not continue to be used, otherwise the engine operating conditions will be more to worse, can not even work properly. When the air cleaner filter is clogged to the suspended particles can not meet the required air flow engine, the engine will be abnormal working conditions, such as the roar of nausea, accelerate slow (less than the cylinder intake air pressure is not enough), work weakness (due to the mixture too thick and incomplete combustion), the water temperature is relatively higher (into the exhaust stroke combustion continues), and the acceleration exhaust smoke thickens. When these symptoms occur, you can determine the air filter clogging, the filter should be removed for maintenance or replacement. In the maintenance of air filter, the filter should be noted that the inner and outer surface of the color change. After the dust cleared, if the outer surface of the filter paper qualities clear, and its inner surface and bright, you can continue to use; if the outer surface of the filter paper or inner surface has lost its dark gray, it must be replaced.
