Abstract
Methods and systems are provided for improving control of high dilution EGR. An intake plenum is divided so that fresh intake air and EGR can be delivered to engine cylinders via dedicated plenum portions. Distinct sets of throttles are provided in the cylinder intake ports coupled the different plenum portions so that a ratio of intake air flow and EGR flow to the engine cylinders can be rapidly adjusted in response to sudden changes (e.g., increase or decrease) in EGR demand.
