Abstract
A control system operative to establish a coordinated composition of gaseous fuel and distillate fuel specifically adaptable for use in high capacity, off-road, mine haul vehicles and including an electronic control unit structured to modulate a throttle position signal from the vehicle throttle assembly and transmit the modulated throttle position signal to a vehicle engine control assembly. The electronic control unit concurrently generates an auxiliary fuel control signal to a gaseous control unit, dependent at least in part, on the operating modes and operating characteristics of the vehicle. The auxiliary control signal is determinative of a quantity of gaseous fuel to be included in an operative fuel mixture, wherein said modulated throttle position signal and said auxiliary control signal are determinative of the operative fuel mixture on which the vehicle engine operates during predetermined ones of the operating modes of the vehicle engine.
