Abstract
A fuel injection control system suitable for use with internal combustion vehicle engines fueled by compressed natural gas or the like. A conventional liquid-fuel closed-loop injection timing controller establishes the duration of each injection command signal by the combination of a P.I.D. controller responsive to the level of exhaust oxygen, an adaptive table which stores previously determined fuel delivery rate values for particular engine speed and load conditions, an injector supply voltage table which stores fuel delivery rate correction values which compensate for variations in injector operating potentials, and a two-dimensional correction table which provides correction values to compensate for variations due to fuel pressure and resistance variations in the injector actuators due to temperature variations.
