The working principle of the automotive engine filter module assembly
The working principle of the automotive oil filter module assembly is as follows:
Core filtering mechanism
When the engine is running, the oil pump forces the oil into the oil inlet of the filter base plate assembly. Under pressure, the engine oil passes through the outside of the filter paper into the central tube. Impurities are intercepted by the filter paper, while pure engine oil enters the engine lubrication system.
Structure and Classification
Youdaoplaceholder0 full-flow filter : connected in series between the oil pump and the main oil passage, it filters all the lubricating oil entering the main oil passage.
Youdaoplaceholder0 Split type filter : Connected in parallel with the main oil passage, it only filters part of the lubricating oil.
Differences in filter element types
Youdaoplaceholder0 Modular filter element (commonly found in German cars) : The housing is fixed and the internal filter element can be repeatedly replaced. It is environmentally friendly but the replacement process is slightly more complicated.
Youdaoplaceholder0 Rotary filter element (commonly found in Japanese cars) : The housing and filter element are designed as one, making replacement convenient but requiring a complete replacement.
This assembly removes metal shavings, dust and other impurities from the engine oil through physical barrier methods, ensuring the cleanliness of the lubrication system of engine components.
The "automotive oil filter module assembly" (commonly known as the oil filter assembly) refers to a system that integrates multiple components related to the oil filtration function into a single module . It is not merely a single filter element, but an independent unit that contains multiple components and has complete filtration functions. The specific meaning can be understood from the following two aspects:
Core function: Oil filtration
The function of : is responsible for filtering impurities in engine lubricating oil (engine oil), such as metal shavings, carbon deposits, dust, etc.
Youdaoplaceholder0 Importance: Clean engine oil is crucial for the lubrication, cleaning, cooling and rust prevention of the moving parts inside the engine, such as crankshafts, connecting rods and camshaft bearings. Filtering impurities can effectively reduce part wear and extend engine life .
Youdaoplaceholder0 Maintenance cycle: is generally recommended to be replaced every 10,000 to 20,000 kilometers or as required by the maintenance manual, often at the same time as the engine oil .
The meaning of "assembly" is
Youdaoplaceholder0 Integrated component: "assembly" means it is not a single part, but a fully functional independent module composed of multiple related parts to form . For an oil filter assembly, its interior typically includes:
Youdaoplaceholder0 Filter element: core filtration element (made of paper, synthetic fiber, etc.), responsible for retaining impurities.
Youdaoplaceholder0 shell/base: provides structural support, including oil inlet and outlet ports and installation interfaces.
Youdaoplaceholder0 Bypass valve: automatically opens when the filter element is clogged or the oil viscosity is too high, ensuring that some unfiltered oil can still flow to the engine and preventing serious damage caused by oil circuit interruption.
Youdaoplaceholder0 Check valve (partially designed) : prevents the oil from flowing back after the engine stalls, ensuring that the oil pressure can be quickly established during the next start-up .
In summary
Youdaoplaceholder0 automotive oil filter module assembly = oil filter + its matching housing, valves and other components = an independent, fully disassemblable and replaceable oil filtration function module. Youdaoplaceholder0 It is an indispensable key component of the engine lubrication system, protecting the engine by filtering the engine oil .
The difference from other filters
Youdaoplaceholder0 Oil filter assembly: is specifically designed for filtering engine lubricating oil .
Youdaoplaceholder0 Air filter assembly: is used to filter the air entering the engine combustion chamber and is usually located at the front end of the intake pipe .
Youdaoplaceholder0 fuel filter: is used to filter impurities from gasoline or diesel and protect the fuel system (fuel injectors, fuel pumps, etc.) .
Therefore, when the term "oil filter module assembly" is mentioned, it specifically refers to the entire integrated device responsible for filtering engine oil. Regular replacement of it is crucial for maintaining the health of the engine .
The failure of the oil filter module assembly is usually manifested as symptoms such as the engine fault light being on, weak acceleration, and abnormal noises, which may be accompanied by a drop in oil pressure or clogging of the filter element. The following are the specific reasons and solutions:
Common causes of faults
Youdaoplaceholder0 Filter element clogging : Long-term failure to replace or the use of low-quality oil filters can lead to filter element clogging, affecting oil flow and causing abnormal lubrication systems.
Return oil valve failure ** : A damaged return oil valve can cause abnormal drops in oil pressure and requires professional inspection or replacement.
Youdaoplaceholder0 Oil pump problem : Wear or excessive clearance of the oil pump may cause insufficient oil supply, and the relevant components need to be replaced.
Youdaoplaceholder0 Oil circuit blockage : Insufficient engine oil quantity, clogged oil pipes or poor ventilation in the crankcase can all lead to a decline in lubrication effect.
Solution
Youdaoplaceholder0 Replace the filter : Immediately replace the qualified oil filter and clean the impurities in the oil passage to avoid using inferior parts.
Youdaoplaceholder0 Check the oil circuit : Clear the blockages in the oil circuit to ensure the normal operation of the oil pump.
Youdaoplaceholder0 Adjust the maintenance cycle : Change the engine oil and filter regularly as required by the vehicle manual to avoid long-term use of inferior engine oil.
If the fault persists, it is recommended to contact a professional maintenance institution for a system inspection.
