Description

technical field

[0001] The invention relates to the technical field of motor vehicle filters, in particular to a centralized control method for motor vehicle filters. Background technique

[0002] Air filters, fuel filters, and oil (ie, lubricating oil) filters are three types of filters that are necessary on a motor vehicle. The air filter plays an important role in ensuring the cleanliness of the engine intake, the fuel filter is used to ensure the cleanliness of the engine fuel, and the oil filter is used to ensure the cleanliness of the lubricating oil in the motor vehicle lubricating oil system. When each filter reaches the designed working time or working mileage, a new filter element needs to be replaced to ensure the normal function of each filter.

[0003] Original filter elements are more expensive, so end users of motor vehicles sometimes replace non-original filter elements when replacing filter elements. Non-original filter elements vary from good to bad, and ...
