Abstract
Methods and systems are provided for improving a balance between engine fuel economy and exhaust emissions in an off-highway vehicle. One example method includes adjusting an engine injection timing based on an ambient NOx level estimated by a NOx sensor in the engine intake. Another example method includes adjusting a trip plan with a time in notch duty cycle based on a deviation from the time in notch duty cycle from a reference duty cycle.
