PURPOSE:To automatically switch fuel without disorder of air-fuel ratio by swtiching the set value and controlling the calculation of a feed forward when two or more types of fuels are used. CONSTITUTION:An air flow rate regulating meter 39 compares the output of an excess air ratio conversion factor (mu) with the root conversion value of an air flow rate to obtain a signal for reducing a deviation, and applies the calculated value through a feed forward calculation controller 40 to an air flow rate control valve 31 as an air flow rate operation signal. The controller 40 directly adds feed forward amounts DELTAMV1, DELTAMV2 to the output of the meter 39 to control the operation of the flow rate control valve 31. Thus, the fuel can be automatically switched without disorder of air-fuel ratio. |
