There are two types of oil filters: coarse filters and fine filters. The coarse filter is generally connected in series in the main oil circuit, and the pore size of the filter paper element is generally 15. The coarse filter adopts a spin-on type, and its safety valve and filter element are install
Air-cooled engines use air as the cooling medium. When the air blows through the heat-dissipating surface at high speed, it brings out the heat of the machine parts. Therefore, the function of the cooling system is mainly to ensure that the engine works under the most suitable temperature state. To
According to the provisions of the American Petroleum Engineering Society (AP1), engine oil grade classificationWhen selecting oil according to the "API" classification, always select the highest level "API" level corresponding to the US standard or Deutz level. For example, for HDB, use CC level in
1. Reduce friction. Lubricating oil can maintain a certain oil film under high temperature and high pressure. The oil film is formed by the action of additives, not the oil itself. Due to the presence of the oil film, the friction of the liquid is maintained during the operation of the machine, thus
