Abstract

Certain embodiments of methods and systems for operating an internal combustion engine over a range of operating condition are disclosed. One embodiment of a method includes operating the engine at an initial 02 voltage ^fe setpoint; and automatically adjusting the 02 voltage setpoint to a new 02 voltage setpoint to reduce emissions. In certain embodiments a control system for controlling emissions in an internal combustion is provided. The control system includes at least one subsystem that controls an 02 voltage setpoint; at least one subsystem that measures NOx emissions in the engine exhaust; and at least one subsystem that initiates a lambda sweep to determine an optimal 02 voltage setpoint.
