  • Air flow meter
    • A device that measures air flow/how much air is flowing through a tube
    • Does not measure the volume of the air passing through the tube
    • Measures the mass of air flowing through the device per unit of time
    • Kilograms per second (kg/s)
    • Measures the quantity of air going into the engine
    • Differential pressure is also used for air flow measurement
    • Generally located in the plastic housing between the engine and the air filter
    • An electronic sensor that sends a signal to the engine computer, which then uses the measurements to help calculate fuel delivery and spark timing
