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

Abstract

PURPOSE:To improve properties of exhaust gas and output by feedback controlling air fuel ratio when fuel supply is less than a first reference value, open-loop controlling same when the fuel supply is between the first reference value and a second reference value and increment correcting same when the fuel supply is higher than the second reference value. CONSTITUTION:To a control circuit 20 are input detecting values of an O2 sensor 1, throttle valve opening sensor 10, absolute intake pressure sensor 11, crank angle sensor 12, water temperature sensor 13, etc., to control calculatively a fuel injection valve 5. The control circuit 20 feedback controls air fuel ration when cooling water temperature is higher than a predetermined one, rotational frequency falls within a predetermined extent and calculated fuel injection time is less than a first reference value. When the fuel injection time exceeds the first reference value, the throttle valve opening is more than a predetermined value and the fuel injection time is more than a second reference value which is lessened as the rotational frequency becomes high, an incremental factor in full opening is set.
