摘要：A fuel injection control method for successively injecting fuel into a plurality ofcylinders of an internal combustion engine in predetermined sequence in synchronismwith pulses from top-dead-center detecting means which are successively generatedimmediately after generation of each pulse from cylinder-discriminating means. Themethod is adapted to perform a fail safe function in the event of occurrence of anabnormality in the cylinder-discriminating means. The number of pulses is counted whichare successively generated from the top-dead-center detecting means immediately aftergeneration of each pulse from the cylinder- discriminating means. If no further pulsefrom the cylinder- discriminating means is detected until the count of pulses from thetop- dead-center detecting means reaches a number equal to the sum of the number ofthe engine cylinders and while the rotational speed of the engine is higher than apredetermined value, the cylinder-discriminating means is regarded as abnormal. Then,injection of fuel into the cylinders is effected in the above predetermined sequence insynchronism with pulses from the top-dead-center detecting means alone, irrespective of
generation of subsequent pulses from the cylinder-discriminating means.
