What is the Function of an Air Flow Meter?
1 Answers
Air flow meter is used to: detect the intake air volume of the engine, and convert the information about the amount of engine intake air into electrical signals to be sent to the ECU. Automotive air flow meters are mainly divided into vane-type air flow meters, Karman vortex-type air flow meters, optical Karman vortex air flow meters, and ultrasonic Karman vortex air flow meters, which are mainly used in industrial production, environmental protection, transportation, biotechnology, scientific experiments, and water systems. The symptoms of a faulty automotive air flow meter are: 1. unstable idle speed; 2. increased fuel consumption; 3. weak acceleration; 4. severe exhaust emissions pollution.
