Fuel bucket scheduler

Abstract

A fuel control system for an internal combustion engine includes a processor for determination of the timing and length of control pulse signals to an injector driver for turning an injector on and off. The method and an apparatus for delivering fuel to the injectors is according to a schedule that is adjusted throughout a variety of operating conditions with a minimum of chronometric or throughput loading by scheduling a circular queue of a plurality of buckets determined as a predetermined portion of a combustion cycle. Each bucket is defined by an interval initiated by an event triggered interrupt. At the interrupt, the processor dequeues a list of pointers to fueling information data storage for each cylinder previously assigned to the bucket. The method then assigns each cylinder to at least one selected bucket according to predetermined logic determination and an injector demand signal.
