ABSTRACT:
A fuel control system having an auxiliary circuit for correcting the signals generated by a pressure sensor under transient operating conditions is disclosed. The circuit generates a pressure correction signal directly proportional to the first time derivative of the intake manifold pressure and inversely proportional to rotational speed of the engine which is added to the signal generated by the pressure sensor. The added signals are utilized by the electronic control unit for computing the fuel requirements of the engine to maintain a constant fuel/air ratio during steady state and transient operating conditions.
