Abstract

An inter-cylinder-injection fuel controller for an internal combustion engine which offers fail-safe performance against an increase in the amount of the intake air caused by a trouble in the intake system, and reliably suppresses the engine running speed from abnormally increasing. The fuel controller comprises various sensors 20 for outputting data representing operation conditions of the internal combustion engine, injectors for directly injecting the fuel into the cylinders, and a control unit 89 for operating the amounts F of fuel supplied into the cylinders based upon the operation conditions and for controlling the injectors based upon the amounts of supplying fuel, wherein said various sensors include an amount-of-intaken-air sensor for outputting data that corresponds to the amount Qa of the intaken air, and a crank angle sensor for outputting data .theta. that correspond to the running speed Ne and to the crank angle, and the control unit limits the width of the injection control signals J for the injectors to an upper-limit value that corresponds to the operation conditions.
