The filter accuracy of oil filter is within 10 μ～ fifteen μ Its function is to remove impurities in the oil and protect the normal operation of the bearing and rotor. If the oil filter is blocked, it may cause insufficient fuel injection, affect the service life of the main engine bearing, increase the exhaust temperature of the engine head or even shut down.
Why use variable displacement oil pump?
When the engine speed gradually increases, the pump oil volume and pressure of the oil pump will increase with the increase of the speed. After the pump oil volume and pressure meet the lubrication requirements, the continuous increase will consume more engine power.
