ABSTRACT:
Methods are provided for operating an engine with a variable fuel blend in a cylinder, where the variable fuel blend varies a peak achievable engine torque for a given operating condition. One example method comprises selectively operating an engine actuator that affects engine torque and engine fuel economy at the given operating condition, and extending operation of the actuator to higher engine torques as a peak engine torque for the given operating condition increases.
