The function of oil filter
► Oil filter, also known as oil filter. It is used to remove
impurities such as dust, metal particles, carbon sediments and soot
particles in the oil to protect the engine.
► Oil filters are divided into full-flow and split-flow types. The
full-flow filter is connected in series between the oil pump and
the main oil channel, so it can filter all the lubricating oil
entering the main oil channel. The split-flow filter is connected
in parallel with the main oil channel and only filters part of the
lubricating oil sent by the oil pump.
Technical features:
● Filter paper: Oil filters have higher requirements for filter
paper than air filters, mainly because the temperature of the oil
varies from 0 to 300 degrees. Under drastic temperature changes,
the concentration of the oil also changes accordingly, which will
affect the filtration flow of the oil. The filter paper of a
high-quality oil filter must be able to filter impurities under
drastic temperature changes while ensuring sufficient flow.
● Rubber seal ring: The filter seal ring of high-quality oil is
synthesized with special rubber to ensure 100% oil leakage.
● Backflow suppression valve: Only available in high-quality oil
filters. When the engine is turned off, it prevents the oil filter
from drying out; when the engine is re-ignited, it immediately
generates pressure to supply oil to lubricate the engine. (Also
called check valve)
● Overflow valve: Only available in high-quality oil filters. When
the external temperature drops to a certain value or when the oil
filter exceeds the normal service life, the overflow valve will
open under special pressure to allow unfiltered oil to flow
directly into the engine. Even so, impurities in the oil will enter
the engine, but the damage caused by no oil in the engine is much
less. Therefore, the overflow valve is the key to protecting the
engine in an emergency. (Also called bypass valve)
