Abstract
A failure-time control device for a fuel injection controller of an internal combustion engine provided with a failure-time by-pass throttle valve control device to maintain a by-pass throttle valve at a definite aperture on the basis of an output signal from a trouble detecting device for detecting trouble occurred in an intake air flow detecting device; and a failure-time fuel injection valve control device which calculates a fuel quantity on the basis of a relationship of a fuel injection quantity with respect to an aperture of a main throttle valve to be determined by a definite aperture maintained by said by-pass throttle valve and the number of revolution of the engine, based on an output signal from said trouble detecting means, and which feeds by injection the fuel into the internal combustion engine by controlling the fuel injection valve on the basis of the quantity as calculated.
