ABSTRACT:
An air flow metering apparatus for measuring a suction air flow fed to an internal combustion engine comprises at least two Karman' vortex type air flow meters disposed separately in at least two air suction passages, respectively. The output signals from the flow meters are switched in such manner that in a predetermined range of high air flow rates, the output signal from one of the flow meter is utilized for measuring or sensing the air flow rate, while in a predetermined low flow rate range, the output signal from the other flow meter is utilized for the same purpose. Alternatively, in a predetermined low flow rate range, only one of the air suction passages is employed, while both of the air suction passages are employed in a predetermined range of high air flow rates. The air flow metering apparatus assures the detection or measurement of the suction air flow rate over a whole operation range of the engine with a high reliability and enhanced accuracy.
