Abstract

See full text

A fuel control module, based on an engine torque request, fuels N cylinders of an engine using a first fuel system. N is an integer greater than zero. A throttle control module, based on the engine torque request and the fueling of the N cylinders using the first fuel system, opens a throttle valve to a predetermined wide open throttle (WOT) position. A cost module, when the engine torque request is greater than a predetermined torque: determines a first cost value for fueling at least one of the N cylinders of the engine using a second fuel system; and determines a second cost value for adjusting at least one operating parameter other than fueling of the engine. An adjustment module, based on, the first and second cost values, one of: initiates the fueling of the at least one of the N cylinders using the second fuel system; and adjusts of the at least one operating parameter other than fueling of the engine.
