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, a threshold temperature at which the spark ignition engine may be automatically stopped is adjusted according to an amount of soot that is stored in the particulate filter.
