    摘要： Systems and methods for controlling regeneration of a particulate filter downstream of an engine having a plurality of cylinders are provided. One exemplary method includes, during first conditions, spinning down the engine to non-combusting engine rest, and regenerating the particulate filter at least during engine rest. The method also includes, during second conditions, regenerating the particulate filter during combustion of at least one cylinder of the engine. By regenerating the particulate filter during engine shutdown and/or engine rest in some conditions, it is possible to reduce engine running regeneration, which can thereby lead to reduced engine running emissions.

    摘要： A method of operation of an internal combustion engine including an intake valve coupled to a combustion chamber, and a port fuel injector positioned upstream of the intake valve in an intake manifold including a throttle, the port fuel injector fluidly coupled to a fuel rail included in a fuel delivery system housing a fuel at least partially composed of alcohol. The method including, during a start-up operation when the temperature of the engine is below a threshold value and fuel is actively being injected into the intake manifold, adjusting a cone angle of a fuel spray from the port fuel injector, via adjustment of the throttle and/or fuel delivery system, based on the position of the intake valve.

    摘要： Systems and methods for controlling regeneration of a particulate filter downstream of an engine in a vehicle are provided herein. One exemplary method includes, during an engine shutdown, increasing a throttle opening and regenerating a particulate filter downstream of a three-way catalyst. The method also includes, during an engine start following an engine shutdown, setting one or more engine parameters based on whether the particulate filter was regenerated during a last engine shutdown before the engine start.
