The air flow meter of the car is broken, what effect will it have?

The air flow meter of the car is broken, which will have some effects: unstable idle speed, increased fuel consumption and weak acceleration.

A specially designed patent guide frame is installed at the entrance of the flowmeter, which accelerates the airflow entering the flowmeter with the increase of flow velocity. The design of the guide frame can eliminate any potential fluid disturbance, such as eddy current or asymmetric flow. The driving force of the turbine blades also increases.

Classification of principles:

The air flowmeter has simple structure and high reliability; The so-called Karman vortex street air flowmeter with large air intake resistance, slow response and larger volume means that when a cylindrical or triangular object is placed in the fluid, two rows of vortices with opposite rotation directions will be generated downstream of the object and appear alternately.

In the process of producing Carmen vortex, the air pressure on both sides of the vortex generator will change and act on the metal foil through the guide hole, thus making it vibrate. When the LED light shines on the vibrating metal foil, the reflected light on the metal foil received by the phototransistor is the vortex modulated light.
