What is oil filter and what is its application?    

Oil is a vital force for your car’s engine. Clean engine oil is very important. The engine oil absorbs all contaminants and in simpler term (masses) from the whole system, besides lubricating the internal parts of the engine. Of course, these contaminants will damage the engine. Over time and aggregation of these masses may cause engine failure. Dirty oil can cover the oil pump components in the engine, and damage to the engine’s bearing level.

Oil filters are used in various types of machinery.

Oil filter is placed on the entry path of oil to the engine. Its function is absorbing contamination caused by high performance of the engine, such as metal scraps from wearing parts on each other, soot from combustion, dust, and other pollutants, which can gradually block the oil route and damage the engine. Moreover, this filter refines the oil to be free of any impurities. This vehicle improves the oil performance and cools the engine by heat transfer, besides maintaining the oil clean under conditions such as initial start in cold weather, high pressure due to successive trips, and high temperature of the engine during long operations and high speed.

All moving parts of the engine require clean oil for lubrication. If oil is not filtered, tiny metal particles enter the engine and cause wearing of its components.


High quality filter:

A high quality oil filter has these specifications and capabilities: lack of resistance to oil entry, optimal separation of particles from oil, the power to absorb more pollutants, resistance to tear, an efficient chamber with high pressure tolerance, proper sealing, and also having a safety valve. In making a variety of high quality filters, in addition to use suitable paper, other things are also considered, including no leakage in media filter, proper placement (fitting) of the filter in the shell, the type of alloy used in the compartment, and optimal color coverage.

Effects of using poor quality oil filters:

Filters with inappropriate paper and a seam at the site of the paper connection, do not perform the filtration operation properly can cause entering particles and contaminations to the engine. These pollutants scratch the internal components of the engine, cylinder and piston and damage seriously the engine. The results of these damages can be: dripping oil from the filter connection, rusting the compartment cover, intolerance of pressure, and finally creating a gap in the filter or separation of sealing gasket from the base of the filter. Ultimately, the oil will gradually or rapidly exit from the lubrication path of the engine, and over time this will result in engine wear and tear.

Filters can do their job well only for a certain time. If the oil filter is not replaced on time, the pores of the filter paper are blocked. In this case, due to the pressure rise in the oil filter compartment, the safety valve embedded in it is opened and allows the oil to enter the lubrication cycle without refining in order to prevent total damage to the engine parts. This issue causes serious problems in sensitive parts of the engine.

The replacing time of filters is announced by the manufacturer.
