    摘要： An air-fuel ratio feedback control is provided To prevent over-rich and over-lean of an air-fuel mixture.
    An air-fuel ratio setting section 50 sets a target air-fuel ratio KCMD according to engine conditions. An air-fuel ratio correction coefficient calculating section 51 calculates an air-fuel ratio correction coefficient KAF for controlling the air-fuel ratio so that a detected air-fuel ratio KACT is converged to the target air-fuel ratio KCMD.
    To prevent over-rich and over-lean of the air-fuel mixture, a lower limit section 52 constrains the air-fuel ratio correction coefficient KAF so as not to underrun the lower limit value, and an upper limit section 53 constrains the air-fuel ratio correction coefficient KAF so as not to exceed the upper limit value. A basic fuel injection time determining section 54 calculates a basic fuel injection time TIM, and a fuel injection time calculating section 55 calculates a fuel injection time TOUT based on the target air-fuel ratio KCMD, the air-fuel ratio correction coefficient KAF, the basic fuel injection time TIM or the like, and various engine parameters.

    摘要： Control apparatus, typically for carburettors, which comprises an actuator device (20) having a permanent magnet armature and a pair of coils surrounding the permanent magnet, and a microprocessor (18) responsive to certain parameter-sensed variables including pressure (12), temperature (14), throttle conditions (16) and oxygen content (10) in order that these variously sensed parameters can be com- municatedtothe microprocessor wherein there is transduced by algorithm either a digital signal or an analog signal. The digital or analog signal is then fed to the actuator device in the form of a demand signal for currentflowto the armature coils. The coils upon energisation mechanically displace the arma- tureto effect mechanical transducing ofthe electrical signal to control an actuator rod effecting orifice control. The armature thus effectively controls the orifice size, which in turn determines fuel/air ratio for an internal combustion engine, in conjunction with a carburettor function. Fuel-air control creates operating conditions which in turn are re-sensed by the sensors, the sensors in turn repeating their operation so that there is provided a closed loop servo system either by digital oranalog signals.
