What is an oil filter?
The oil filter is placed in the way of the oil entering the engine, where pollution caused by the high performance of the engine such as: metal shavings caused by the wear of parts on each other, soot caused by combustion, dust and other pollutants that can gradually block the path of the oil. block and cause harmful damage to the engine by absorbing it from the engine oil and purifying the oil so that it is free from any impurities and this device, in addition to the cleanliness of the oil in conditions like The initial start in cold weather maintains the high pressures caused by successive trips and the high temperature of the engine during long operation and high speeds. >
High quality filter properties
A high-quality oil filter has characteristics and features such as: no resistance to oil entry, optimal separation of particles from oil, the ability to absorb more pollution, resistance to tearing, a useful chamber with the ability to withstand high pressure, proper sealing, and also It has a safety valve.
In making all kinds of high-quality filters, in addition to the use of suitable papers, other things are also taken into account, including the absence of leakage in the filter media, placement (shown) the correctness of the filter in the shell, the selection of the type of alloy used in the chamber and the desired color coating.
How the oil filter works
The oil pump installed in the lubrication system, which receives its energy from the timing belt or the propeller belt, directs the oil from the special tank to the filter. The oil flows through the holes on the top of the filter to the cleaning part. The number and radius of these holes determine the flow rate of the incoming oil. The larger and larger the holes, the more oil will enter the filter, as a result, the pressure and volume of the oil entering the engine will also increase.
In this way, there is a safety valve behind the mounts on the filter that prevents foreign contamination from entering it. It prevents After the oil passes through the holes, it opens this valve with pressure and enters the main part of the filter, and the valve closes immediately after the oil passes to protect the cleaning part again and prevent the oil from escaping. The holes and the protective valve are installed in such a way that the oil enters the main chamber from the sides. In the main part, which is also the purifying part, there are filters made of cellulose or synthetic fibers, through which the oil is completely cleaned and its possible contaminations are removed. These filters are rotated around a hollow cylinder in the form of blades of a turbine, and the wall of the cylinder has holes that form the continuation of the oil path. When the oil enters this cylinder, it moves towards the outlet and then the engine.
