Air filter has a great influence on the service life of the engine
Abstract: When piston machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains impurities such as dust, it will aggravate the wear of the parts, so an air filter must be installed.
When piston machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains impurities such as dust, it will aggravate the wear of the parts, so an air filter must be installed.
Among the thousands of parts and components of a car, the air filter is an extremely inconspicuous component, because it is not directly related to the technical performance of the car, but in the actual use of the car, the air filter is The service life of the car (especially the engine) has a great influence.
How to identify the air filter needs maintenance or replacement
First: The service life and maintenance interval of the air filter can be measured by the ratio of the gas flow rate of the flow filter element to the gas flow required by the engine. When the flow rate is greater than the flow rate, the air filter works normally; when the flow rate is equal to the flow rate, the air filter should be maintained; when the flow rate is less than the flow rate, the air filter can no longer be used. Note that if you still choose not to replace the air filter at this time, it will cause the engine to become worse and worse, or even unable to work.
Second: When the filter element of the air cleaner is blocked by suspended particles and cannot meet the air flow required by the engine, the working state of the engine will be abnormal: 1. The cylinder pressure is not enough due to insufficient air intake, which will cause The roar of the engine is muffled and the acceleration is slow; 2. The combustion is not complete due to the excessively rich mixture, which will cause the engine to work weak; 3. If the water temperature of the engine rises relatively, it means that the combustion is still in the exhaust stroke. Continue; 4. When the car accelerates, the exhaust smoke of the engine becomes thicker, etc.
Third: 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 filter element of the air filter, pay attention to the color change of the inner and outer surface of the filter element; after removing the dust, if the outer surface of the filter paper is clear and the inner surface is bright, the filter element can continue to be used; When the surface has lost its natural color or the inner surface is dark, you must choose to replace it.
Editor's Tip: When the car engine is running, the air intake is intermittent, which will cause the air in the air filter housing to vibrate. If the air pressure fluctuates too much at this time, it will affect the engine intake . In addition, in order to suppress the intake noise, the volume of the air cleaner housing can be increased, and some partitions are also arranged in it to reduce resonance.
