Product Details

The oil filter, also referred to as the filter, is an indispensable component of engine operation. The following is a detailed introduction to the oil filter:

1. Definition and function

The oil filter is used to remove impurities such as dust, metal particles, carbon precipitates and soot particles from the oil to protect the engine. By filtering out harmful impurities in the oil, it ensures that the crankshaft, connecting rod, camshaft, piston ring and other moving parts are provided with clean oil, so as to play the role of lubrication, cooling and cleaning, and help to extend the service life of parts.

2. classification and structure

Oil filters are mainly divided into two types: full-flow filter and shunt filter. The full-flow filter is connected in series between the oil pump and the main oil passage, and can filter all the lubricating oil entering the main oil passage. The shunt filter is in parallel with the main oil passage, and only part of the lubricating oil sent out by the filter oil pump.

In terms of structure, the oil filter is mainly composed of two parts: filter paper and housing, as well as auxiliary parts such as sealing ring, support spring, bypass valve and so on. Filter paper is the core component of oil filter, and its quality directly affects the filtering effect of filter.

3. the working principle

The working principle of the oil filter is: during the operation of the engine, with the operation of the oil pump, the oil with impurities enters the oil filter from the oil intake port on the bottom assembly of the oil filter, and passes through the check valve to the outside of the filter paper for filtration. Under the action of oil pressure, the oil continues to pass through the filter paper into the center tube, and the impurities in the oil remain on the filter paper.

4. performance requirements

The oil filter should have strong filtration capacity, small flow resistance, long service life and other properties. At the same time, it also needs to be able to adapt to higher oil temperatures and corrosion environments to ensure that it can work properly under harsh conditions.

5. Replacement and maintenance

In order to ensure the filtering effect of the oil filter, it is recommended to change the oil and oil filter regularly as recommended by the automobile manufacturer. When replacing the oil filter, select the filter that matches the engine model and oil type, and follow the correct installation steps to ensure that it works properly. In addition, it is also necessary to pay attention to check whether there is oil leakage or damage to the oil filter and deal with it in time.

6. Importance

Oil filter is an indispensable part of engine lubrication system. It protects the engine by filtering impurities in the oil, improves the circulation efficiency of the oil, and maintains the stability of the oil. If the oil filter fails or is damaged, the impurities in the oil will not be effectively filtered out, which will cause serious wear or damage to the precision components inside the engine, and even lead to the engine being scrapped.

In summary, the oil filter plays a crucial role in the operation of the engine. Therefore, the owner should pay attention to the selection and replacement of the oil filter to ensure the normal operation of the engine and extend the service life.
