There are many sections within the engine where friction occurs between parts in contact.
While driving these areas of friction become extremely hot, which can cause seizure or parts to melt, which in turn can cause a serious accident.
For that reason it is necessary to reduce the frictional resistance by creating an oil film, making the rotating and sliding sections of the engine run smoothly. To accomplish this the lubrication system circulates oil for lubrication and continuously supplies oil to each part.
Oil pump
Pumps oil that has accumulated in the oil pan, applying pressure and sending the oil to the various parts of the engine.
Driven rotor - Drive rotor - Relief valve
Oil pressure warning light
This is a device that notifies the driver whether the oil pressure pumped to each part of the engine from the oil pump is normal or abnormal.
It is a mechanism that detects the state of the oil pressure using sensors installed in the oil passage.
The light is used to inform the driver when the oil pressure decreases. There is also an oil pressure gauge system that gives notification of this state using a needle.
Oil filter
The oil pumped by the oil pump is contaminated with foreign objects such as metallic dust that could not be removed by the oil strainer.
The oil filter removes these, protecting against wear and the engine seizing.
A relief valve is built into the integrated type filter, so that oil will pass if the element becomes clogged. For the element replacement type, only the internal elements can be replaced separately.
The integrated filter has a built-in relief valve that allows oil to pass through if the element becomes clogged. The check valve prevents foreign matter accumulated in the element from flowing back to the pump when the engine is stopped.
