SYSTEMS AND METHODS FOR LP-EGR DELIVERY IN A VARIABLE DISPLACEMENT ENGINE

Methods and systems are provided for controlling LP-EGR flow in a variable displacement engine. In one example, a method may include providing a higher fixed LP-EGR percentage relative to a total intake air flow during a VDE mode, and providing a lower fixed EGR percentage relative to the total intake air flow during a non-VDE mode. Further, during a tip-out when operating in the VDE mode at a load below a threshold, transitioning out of the VDE mode after transitioning the LP-EGR from the higher fixed percentage to the lower fixed percentage.
