DEDICATED-EGR CYLINDER WITH VARIABLE CHARGE MOTION

摘要

Methods and systems are provided for adjusting charge motion control devices coupled to a series of cylinders organized into cylinder groups, one of the cylinder groups including a dedicated EGR cylinder group wherein the cylinders are the only engine cylinder routing exhaust to an engine intake. In one example, a first cylinder group may be a dedicated cylinder group recirculating exhaust to the intake manifold while a second cylinder group may be a non-dedicated cylinder group routing exhaust to a turbine. A method may include adjusting a first charge motion control device coupled to the first cylinder group and a second charge motion control device coupled to the second cylinder group to vary a charge motion level between the first and second cylinder groups.

1. A method for an engine, comprising:
adjusting each of a first charge motion control device coupled to a first cylinder group and a second charge motion control device coupled to a second cylinder group to vary a charge motion level between the first and second cylinder groups while recirculating exhaust from only the second cylinder group to an intake manifold.
