Summary: | A potentiometer wherein the sliding contact is pivotable by the flap of an air flow rate metering gauge in the intake manifold of an internal combustion engine with fuel injection into the manifold, and the stationary resistor track of the potentiometer is provided with spaced-apart metallic strips each of which is connected with at least one resistor. The strips are thin enough to be cut by the sliding contact and each thereof extends from a discrete fixed contact adjacent to a convex edge face of the track all the way to a concave edge face of the track. The potentiometer is connected with a control circuit which determines the duration of pulses serving to effect an opening of fuel injection valves. |
