Abstract
Systems and methods for operating a spark ignition engine that includes a particulate filter in the engine's exhaust system are described. In one example, the spark ignition engine is prevented from exceeding a threshold engine load when the engine is supplying power to an electric machine so that engine emissions may be reduced.
