Zusammenfassung:	A method of operating an internal combustion engine includes the steps of: determining an upper torque curve at which exhaust emissions from the internal combustion engine are acceptable; determining a lower torque curve at which exhaust emissions from the internal combustion engine are acceptable; and operating the internal combustion engine using a command torque curve ranging between the lower torque curve as a lower limit and the upper torque curve as an upper limit.
