What do you know about the function of car air flow meters?
The automotive air flow meter is a sensor that develops precision components and can calculate the engine intake volume. In the electronic fuel injection system of automobiles, the air flow meter is one of the important components that affect the system control accuracy.. Meanwhile, the gas consumption signal and engine speed signal serve as reference signals for fuel injection timing. The fuel control system is divided into L control that directly measures the intake air volume and D control that indirectly measures the intake air volume based on the characteristics of the air flow meter sensor. The initial electronic fuel injection control system used analog circuits instead of microcomputers, but at that time a valve type airflow sensor was used. Its main performance is to measure speed signals, but because electronic fuel injection control systems were not used at that time, the performance of this sensor cannot meet current needs. In World War II, the Germans successfully developed a new type of electronic fuel injector for measuring engine intake volume. It could directly connect the air flow sensor to the engine speed signal, allowing for the measurement of the required intake volume and effective control of the engine. Since 1945, various countries have conducted extensive research on electronic fuel injection control technology and invested significant funds in the development of electronically controlled fuel injection systems. The rapid development of automotive air flow meters was the foundation for the significant progress made in electronic fuel injection technology at that time, laying a solid foundation for the development of ele
2. What is the function of a car air flow meter?
[Pacific Automotive Network] The function of a car air flow meter is to detect the intake volume of the engine. It can convert the information of the engine intake volume into an electronic signal and send it to the ECU.
. Air flow meters can be divided into the following types: blade type air flow meters have a simple structure and high reliability; But it has a large volume, high intake resistance, and slow response. The so-called Karman vortex in the Karman vortex air flow meter refers to the two columns of vortices that alternate in rotation direction downstream of a cylindrical or triangular object placed in a fluid. During the process of generating Karman vortices in an optical Karman vortex air flow meter, the air pressure on both sides of the vortex generator will change and act on the metal foil through a guide hole, causing it to vibrate. When the light from the light-emitting diode shines on the vibratin
