ABSTRACT:
A method of operating an internal combustion engine including the steps of detecting, determining, and switching. The detecting step detects a load on the engine. The determining step determines if the load is below a predetermined value. The switching step switches the engine to operate at a selected one of a plurality of torque power curves, dependent upon the determining step.
