Problems solved by technology

[0005] The factors mentioned above are likely to cause the car engine to fail to meet the requirements of emission regulations; at the same time, the fuel consumption of the car will also increase significantly
Moreover, the air that enters the engine cylinder without effective filtration is likely to cause excessive wear to the parts in the cylinder, thereby affecting the service life and durability of the engine

Embodiment Construction

[0028] Please refer to FIG. 1 , an embodiment of the present invention provides an air filter monitoring device, which includes a sensor, a control unit and an alarm unit arranged on the engine for monitoring intake resistance.

[0029] The sensor monitors the intake state of the engine, and after obtaining the intake resistance data, transmits the data to the control unit. The control unit compares the input data with the pre-stored standard data; when the input data is equal to or greater than the pre-stored standard data, the control unit sends an early warning command to the alarm unit, and the alarm unit implements the early warning command to send out audio or video early warning information.

[0030] Please refer to FIG. 2 , where, in one embodiment, the sensor 20 is set on the air filter 10 of the automobile engine air intake integration device to measure and monitor its air intake resistance. In other embodiments, the sensor can also be arranged on the intake manifold...

Abstract

The invention discloses an air filter monitoring device, and relates to an automobile engine air intake and exhaust system. The device comprises a sensor which is arranged on an engine and used for monitoring air intake resistance, a control unit and an alarm unit. The sensor monitors the air intake state of the engine, after air intake resistance data of the engine are obtained, the data are transmitted to the control unit, and the control unit compares input data with standard data prestored in the control unit. When the input data are equal to or larger than the prestored standard data, the control unit sends a pre-warning command to the alarm unit, and the alarm unit executes the pre-warning command to send out audio or video pre-warning information.

Description

technical field [0001] The invention relates to an automobile engine air intake system, in particular to an air filter monitoring device used in an automobile engine air intake integrated device, which is used to monitor the state of the air filter element and convert it into information that can be directly received by users. Background technique [0002] At present, in order to ensure the quality of the intake air, the vehicle engine will install an air filter in its intake system to filter out harmful impurities in the air that will enter the cylinder, so as to reduce the air intake of the cylinder, piston, piston ring, valve and valve. Early wear of the seat. [0003] Generally speaking, car users usually judge whether the air filter element needs to be maintained or replaced based on the mileage of the vehicle. However, this basis is affected by the user's memory ability, which may cause the air filter element to be maintained or replaced too late. [0004] Moreover, ...
