ABSTRACT:
An accumulator fuel injection system working to energize fuel injectors to inject fuel at a sequence of injection timings into an internal combustion engine and also to control a fuel pump to feed the fuel to an accumulator at a sequence of controlled times for compensating for the amount of the fuel flowing out of the accumulator under feedback control. When having found a failure in operation of at least one of the fuel injectors, the system alters a mode of the feedback control to decrease the amount of fuel fed to the accumulator at one of the sequence of the controlled times which is at a selected interval away from one of the sequence of the injection timings at which the at least one of the fuel injectors is to be energized, thereby ensuring a steady balance between the amounts of fuel flowing into and out of the accumulator.
