What is the normal air flow value for a BMW Mini?
1 Answers
BMW Mini air flow values between 9-12 are considered normal. Common types of air flow meters: Include vane-type air flow meters, optical air flow meters, Karman vortex air flow meters, ultrasonic air flow meters, hot-wire air flow meters, and hot-film air flow meters. Main functions: They detect the engine's intake air volume or intake air temperature, and some also have the function of measuring external atmospheric pressure. The intake air volume is converted into an electrical signal and sent to the ECM, which then controls the fuel injection volume to achieve optimal combustion efficiency.
