ABSTRACT:
A fuel injection system for an internal combustion engine whose air induction tube contains an air flow rate measuring member with non-linear operating characteristics, coupled to a potentiometric transducer which produces the electric command variable for a follower control loop. A control amplifier drives a servomotor which sets the metering slide of a fuel metering valve assembly. The servomotor shaft is coupled to a second potentiometric transducer whose output is compared with the command variable in a bridge circuit connected to the input of the control amplifier. The mechanical link between the servomotor and the fuel metering slide has a non-linearity similar to that of the air flow rate measuring member.
