Abstract
A dual-fuel engine system for a work vehicle includes an engine with a piston-cylinder arrangement defining a combustion chamber and an engine control unit (ECU). The ECU has a processing and memory architecture configured to execute instructions to deliver to the engine only a first fuel when an operating load of the engine is less than 5 a first predetermined threshold, deliver only a second fuel and operate the engine stoichiometrically when the operating load is greater than a second predetermined threshold. The second predetermined threshold is greater than the first predetermined threshold.
