Abstract
An air flow rate measuring device is proposed for an internal combustion engine. The air flow rate measuring device includes a baffle valve disposed in the air intake tube and a signal generating circuit coupled therewith. A damping member is associated with the signal generating circuit. This damping member serves to damp the so-called over-swings in the output signal caused by the sluggishness of the baffle valve and thereby avoid incorrect fuel metering. Two embodiments of damping members are disclosed, both comprising resistor-capacitor combinations together with a diode, in which the stored capacitor charge assumes the function of damping the output signal of the signal generating circuit.
