ABSTRACT:
A fuel injection control system for a multi-cylinder internal combustion engine mounted in a vehicle is provided. The system works to schedule execution of a sequence of multiple injections of fuel into each of cylinders of the engine and determines whether events of any two of the injections scheduled to be executed in any two of the cylinders overlap in time with each other or not. If so, the system determines which of the two of the injections overlapping each other should be rescheduled based on operating condition of the vehicle and reschedules the execution of one of the two of the injections, as determined to be rescheduled, so as to eliminate overlap with any of the events of the injections. This avoids undesirable application of load on the system or the delay in activating fuel injectors which may arise from simultaneous activation of two of the injectors.
