Abstract
Methods and systems for operating an engine to provide small amounts of energy to heat an aftertreatment device are described. In one example, fewer than the actual total number of engine cylinders are supplied with late post fuel injections (LPI) to heat an aftertreatment device without heating the aftertreatment device more than is desired. The engines fuel injectors may be operated at minimum fuel pulse widths to reduce fuel consumption.
