Claim 7:
8. A method of reducing emissions, comprising:
determining a condition of an exhaust gas from an engine;
comparing the condition of the exhaust gas to a predefined threshold;
in response to determining that the condition of the exhaust gas does not meet the predefined threshold, determining whether an engine operating condition is met for activating a cylinder deactivation operating mode for the engine;
in response to determining that the engine operating condition is met, operating the engine in the cylinder deactivation operating mode by deactivating a cylinder of a plurality of cylinders;
comparing an amount of power available in a power system to a predefined threshold amount of power; and
in response to determining that the amount of power available in the power system is greater than the predefined threshold, activating an aftertreatment system heater to heat the exhaust gas.
