To extend the service life of diesel engines, it is necessary to strengthen the maintenance of the air filter, oil filter, and fuel filter during use, and fully utilize the filtering effect of the filter.

When installing the air filter, it is not allowed to miss, reverse or install the sealing gaskets and rubber connecting pipes incorrectly, and ensure the sealing of each joint. Using a paper dust collector air filter, the dust should be removed once every 50-100 hours of operation. The surface dust can be brushed off with a soft bristled brush. If the working time exceeds 500 hours or it is damaged, it should be replaced in a timely manner. Use an oil bath air filter. After every 100-200 hours of operation, clean the filter element with clean diesel and replace the oil inside. If the filter element is broken, it needs to be replaced immediately. During use, add oil according to regulations.

If the oil filter is not maintained in a timely manner during the use of a diesel engine, it can cause clogging of the filter element, increased oil pressure, opening of the safety valve, and direct flow of lubricating oil into the main oil passage, which will exacerbate the wear of the lubricating surface and affect the service life of the diesel engine. Therefore, the oil filter should be cleaned once every 180-200 hours of operation. If the filter element is found to be damaged, it should be replaced immediately to prevent impurities from entering the lubrication surface. When using diesel engines during seasonal changes, attention should also be paid to cleaning the crankcase, oil ducts, and various lubrication surfaces.

The various fuel filters in the fuel supply system should be cleaned of debris every 100-200 hours of operation, and the fuel tank and various oil pipelines should be thoroughly cleaned. When cleaning the filter element and seals, if any damage is found, it should be replaced in a timely manner. When changing oil during seasonal transitions, all components of the entire fuel supply system should be cleaned. The diesel used should meet seasonal requirements and undergo 48 hours of precipitation purification treatment.
