What is the automotive filter
Automotive filter, the full name of oil filter , is an important part of the automotive engine lubrication system. Its main role is to filter impurities in the oil, such as dust, metal particles, carbon sediments and soot particles, so as to protect the engine from wear and damage.
The function of the filter
Filter impurities : remove dust, metal particles, gum and moisture in the oil to keep the oil clean.
engine : Clean oil is delivered to each lubricating part of the engine to ensure the normal operation of the internal parts of the engine.
extend engine life : reduce the friction resistance between the relative moving parts inside the engine, reduce the wear of parts, so as to extend the service life of the engine.
Classification of filter
full-flow filter : connected in series between the oil pump and the main oil passage, can filter all the lubricating oil into the main oil passage.
shunt filter : in parallel with the main oil passage, only part of the lubricating oil sent by the filter oil pump.
Filter replacement
replacement cycle : It is usually recommended to replace the oil filter every 5000 kilometers or half a year, the specific cycle can refer to the car maintenance manual.
Replacement precautions : The replacement should ensure the quality of the oil filter, avoid using inferior products, so as not to affect the engine performance.
Structure of filter
replaceable : the filter element, spring, sealing ring and other components are placed in the metal shell, and the shell is connected to the metal filter base by a tie rod. The advantage is low cost, the disadvantage is that there are more sealing points, which may lead to leakage.
rotary mounting : the whole replacement, easy operation, good sealing.
The importance of filter
Although the oil filter is small in size, its role cannot be ignored. It is directly related to the lubrication effect and life of the engine, so sufficient attention should be paid to the car maintenance.
By understanding the function, classification and replacement cycle of the oil filter, the owner can better maintain the car engine and ensure its long-term stable operation.
Automotive oil filter (referred to as filter) is an important part of the engine lubrication system, its main function is to filter impurities in the oil to ensure the normal operation of the engine. Here's a breakdown of how it works:
Oil circulation process
After the engine starts, the oil pump pulls the oil from the oil pan and delivers it to the oil filter. After the oil is filtered in the filter, it is then delivered to the various parts of the engine for lubrication and cooling.
Filtering mechanism
After the oil enters the filter, it first passes through the check valve to ensure that the oil flows one-way and gathers on the outside of the filter paper.
Under the action of oil pressure, the oil passes through the filter paper, and impurities (such as metal particles, dust, carbon precipitates, etc.) are intercepted by the filter paper. The filtered clean oil enters the central pipe and is then delivered to the engine's lubrication system.
The function of the bypass valve
When the filter paper is clogged due to the accumulation of impurities, the by-pass valve at the bottom of the oil filter automatically opens to allow the unfiltered oil to enter the engine directly to ensure that the engine will not be damaged by the lack of oil.
Classification of filters
full-flow filter : in series between the oil pump and the main oil passage, filter all the oil.
shunt filter : in parallel with the main oil passage, only filter part of the oil.
Filter performance requirements
The oil filter needs to have strong filtration capacity, low flow resistance, long service life and other properties to ensure the efficient operation of the engine lubrication system.
summary
Automotive filter through filter paper to intercept impurities, bypass valve to ensure lubrication, and full-flow or shunt design to ensure engine oil cleaning and stable operation of the lubrication system. Its working principle is seemingly simple, but it plays a vital role in the healthy operation of the engine.
