Abstract
A gaseous fuel control system for a dual-fuel internal combustion engine comprising a plurality of valves for controlling the amount of gaseous fuel supplied to the engine. The valves have adjustable full-open flow rates and rapidly move from full-open to full-closed in response to a digital signal. An electronic system for monitoring at least one engine operating parameter maps the parameter value to control the opening and closing of the valves to establish a desired gaseous fuel flow rate.
