How the air filter works and when it needs to be serviced or replaced can be identified as follows:
In theory, the air filter life and maintenance intervals should be measured as the ratio of the gas flow rate of the flow filter to the gas flow required by the engine. When the flow rate is greater than the flow rate, the filter works normally; when the flow rate is equal to the flow rate, the filter should be maintained; when the flow rate is less than the flow rate, the filter can no longer be used, otherwise the engine working condition will be more The worse, the even worse.
In actual work, when the filter element of the air filter is blocked by suspended particulate matter and cannot meet the air flow required for the engine work, the engine working condition will be abnormal: if the roaring sound is boring, the acceleration is slow (the intake air is insufficient) The cylinder pressure is not enough); the work is weak (the combustion is incomplete due to the rich mixture); the water temperature is relatively high (the combustion continues while entering the exhaust stroke); and the exhaust smoke becomes rich when accelerating.
When these symptoms appear, it can be judged that the air filter is clogged, and the filter element should be removed in time for maintenance or replacement. When maintaining the air filter element, pay attention to the color change of the inner and outer surfaces of the filter element. After removing dust, if the outer surface of the filter paper is clear and the inner surface is bright, the filter can continue to be used; if the outer surface of the filter paper has lost its natural color or the inner surface is dark, it must be replaced!
