Claim Text:
1. A control system operative to establish a coordinated mixture of gaseous and distillate fuels for a high-capacity off-road vehicle, said control system comprising: an electronic control unit including programming capabilities and recognition capabilities; said programming capabilities operative to recognize a first predetermined number of operating modes and a second predetermined number of operating modes of the vehicle, said recognition capabilities cooperative with said programming capabilities and being operative to recognize operating characteristics of the vehicle, said electronic control unit structured to receive an original throttle position signal from a vehicle throttle assembly and generate a modulated throttle position signal to a vehicle engine control assembly, dependent on said first predetermined number of operating modes, a gaseous control unit structured to generate an auxiliary fuel control signal to said gaseous control unit dependent on said second predetermined number of operating modes, said modulated throttle position signal and said auxiliary control signal determinative of quantities of distillate fuel and gaseous fuel to be included in an operative fuel mixture on which the vehicle engine operates during said first and second predetermined number of operating modes respectively, said operative fuel mixture comprising both said gaseous fuel and said distillate fuel when the vehicle is operating in said first predetermined number of operating modes, said operative fuel mixture comprising said distillate fuel and substantially void of said gaseous fuel when the vehicle is operating in said second predetermined number of operating modes, and said programming capabilities further operative to perform a throttle mapping function comprising the ability to preselect discrete throttle maps for at least some of said first operating modes.
