Types and working principle of filter for single cylinder air cooled diesel engine

Wet filter element and dry filter element are two kinds of filter elements for single cylinder air-cooled diesel engine. Dry air filter is to separate the impurities in the air through a dry filter element; The wet filter element is to filter the air sucking dust particles through the oil pool. After removing most of the dust, the foggy air flows upward through a filter screen made of metal wire. After filtering again, the oil droplets and the blocked dust particles return to the oil pool. The maintenance of the two filtration methods is different. The dry filter element generally takes out the filter element and blows off the dust on the surface. If there is too much dust, the filter element needs to be replaced. The oil filter element has a dust collecting cup under the filter element, which needs to be removed and cleaned regularly. After long-term use, it is necessary to clean the filter screen and oil pool, and replace the oil in the pool. Although the filtering methods are different, they are all to provide clean air for the diesel engine. At present, single cylinder air-cooled diesel engines using dry filter elements are mostly used in diesel generator sets. Diesel engines with wet filter elements are mostly used in agricultural machinery, walking tractors, etc. At the time of purchase, it can also be selected according to the actual use and environment.
