Engine working process, metal debris, dust, carbon dioxide under high temperature and colloidal sediment, water, constantly mixing with oil. Oil filter is to filter out these mechanical impurities and colloidal, cleaning of lubricating oil and extend its lifespan. Top oil filter should have the ability to filter, flow resistance is small, long life performance. General lubrication system mounted with several different filter filters--set the ability of fine filters, strainers and filters, in parallel or in series in the main office, respectively. (With main office in-line full-flow filter, engine oil when all filters filter; Parallel split with filter). A coarse oil filter in-line in the main office, for full-flow; Fine oil filter in parallel in the main office, for the split. On a modern car engine generally has only set filter and a full-flow oil filter
2.Filter's Technical characteristics
Filter Paper: oil filter requirements higher than the air filter on the filter paper, primarily because of oil temperature change range from 0-300, under the violent sudden changes of temperature, concentration of oil changes, which would affect filtering of the oil flow. High quality oil filter under the filter paper to drastic temperature changes, filtering impurities, ensure adequate flow.
Rubber seal: high quality oil filter seal packing collar is made of special rubber synthetic, guaranteed 100% oil spill.
Return restraining valve: only high quality oil filter. When the engine is flameout, it can prevent the oil filter to dry; When you re-ignition engine, it immediately generated pressures, supply of engine oil lubrication.
Relief valve: only high quality oil filter. When the external temperature is reduced to a particular value or when the oil filter out of normal use period, are under particular pressure relief valve to open, unfiltered oil directly into the engine. As a result, impurities in the oil into the engine, but compared to no oil in the engine as a result of the loss, it is much smaller. Relief valve is key to protect the engine in case of emergency.
3.Installation and replacement of filter cycle
Installation:
A)drain or suck the old engine oil
B)drain or suck the old engine oil
C)on the new oil filter seal packing collar put on a layer of oil
D)install the new oil filter and tighten the captive screws
Recommended replacement cycle: cars and commercial vehicles were replaced for this for six months at a time
4.Requirements of automotive oil filters
Precision filtration, filter out particles of all >30um,
Reduce particles into the lubricating gap and cause wear (<3um-30um)
Oil flow in line with the engine of oil demand.
Replacing the long cycle, or at least longer oil life (km)
Filtering accuracy to protect the engine, reduces wear of requirements.
Large capacity ash capacity, suitable for harsh environments.
It can adapt to high temperature and corrosion of oil.
Filter as low oil pressure when possible, the oil can pass smoothly.
