  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To stably control air-fuel ratio over wide range by applying the output signal and the constant frequency voltage of a sensor which detects the engine operation state, to a comparison calculator.
CONSTITUTION: As to a control apparatus which properly prescribes ON-OFF time ratio of a magnetic valve 7 which connects a tank and a pressure controller, the output of a water temperature sensor 50 for engine cooling water is connected to the non-reversal input side of a comparison calculator 37, and to the reversal input side of a triangular wave generator 36. Also an O2 sensor 35 is connected to a comparison calculator 37 at a junction point 3, and the voltage generated at the junction point 3 is controlled by the water temperature sensor 50 and the O2 sensor 35. When the control voltage of the junction point 30 is higher than the triangular wave voltage, the magnetic valve 7 is set to ON, and in the reverse case, magnetic valve 7 is set to OFF, and the ideal air-fuel ratio corresponding to the engine operation state is obtained.
