Anti-counterfeiting and pre-alarm method for air filter and filter element of air filter

Abstract

The invention discloses an air filter, which is used to be installed on a motor vehicle. The casing is provided with an air inlet and an air outlet, and a pressure sensor is arranged at the air outlet; a controller is arranged in the casing, and the controller is used to connect to the vehicle-mounted ECU of the motor vehicle; the invention also discloses a filter element of the air filter The anti-counterfeit and pre-alarm method includes the steps of checking the authenticity of the filter element, the step of condition execution, the step of judging whether the service time of the filter element is overtime, the step of judging the rotational speed, the step of timing the continuous operation of the engine, the step of judging the alarm condition and the step of updating. The present invention has strong anti-counterfeiting performance, and the anti-counterfeiting function of the filter element is difficult to be deciphered; it realizes the pre-alarm, and leaves enough time for motor vehicle users to arrange replacement of the filter element; it has the function of preventing false alarms, and prevents false alarms caused by unstable external conditions, making The invention has good popularization and application value.

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...
