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 desired fuel delivery rate which is then translated into value which controls the duration of each injection command signal. The rate-to-duration translation is performed by accessing stored values which specify the current operating characteristics of the injectors as determined by sensed fuel pressure, fuel temperature and injector actuation voltage values.
