Air filter, and anti-fake and pre-alarm method for filter element of air filter

Abstract

The invention discloses an air filter. The air filter is installed on a motor vehicle and comprises a shell, wherein a filter element is arranged in the shell; a radio frequency identification device(RFID) tag is arranged on the filter element; an RFID reader-writer for reading and writing the RFID tag is arranged on the shell; an air inlet and an air outlet are formed in the shell; a pressure sensor is arranged on the air outlet; and a controller is arranged in the shell and is used for connecting with a vehicle-mounted electronic control unit (ECU) of the motor vehicle. The invention further discloses an anti-fake and pre-alarm method for the filter element the of air filter. The method comprises the steps of checking the authenticity of the filter element, executing conditions, judgingwhether the service time of the filter element is overtime or not, judging the rotate speed, timing the continuous operation of an engine, judging alarm conditions, and updating. According to the airfilter, and the anti-fake and pre-alarm method for the filter element of the air filter provided by the invention, an anti-fake performance is high, so that an anti-fake function of the filter element is difficult to crack; pre-alarm is realized, so that a user using the motor vehicle has enough time to arrange the filter element replacement; and a function on preventing false alarm is realized,and the occurrence of the phenomenon that unstable external conditions cause false alarm is prevented, so that the air filter, and the anti-fake and pre-alarm method for the filter element of the airfilter provided by the invention have favorable popularization and application values.

Description

technical field [0001] The invention relates to the technical field of an air filter. Background technique [0002] The air filter is an important part of the motor vehicle, which plays an important role in ensuring the cleanliness of the engine intake. The filter element is a key part of the air filter. After the designed working time or mileage is reached, a new filter element needs to be replaced to ensure the normal operation of the air 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 the quality cannot be guaranteed; when poor-quality filter elements are used, emissions may not meet standards or even engine damage may occur. After the emission is not up to standard or the engine is damaged, the end users of motor vehicles often think that this is the responsibility of the motor vehicle manufa...
