Abstract
Official abstract text for this publication.
A system includes an internal combustion engine having a number of cylinders, with at least one of the cylinders plumbed to have a complete recycle of the exhaust gases from the cylinder. The system further includes the completely recycled cylinder having an EGR stroke cycle, and the non-recycled cylinders of the engine having an exhaust stroke cycle. The system includes the EGR stroke cycle being distinct from the exhaust stroke cycle. An amount and composition of the exhaust gases from the recycled cylinder are distinct from the amount and composition of the exhaust gases from the non-recycled cylinders, at least at certain operating conditions of the engine.
First claim
Opening claim text (preview).
What is claimed is: 1 . A system comprising: an internal combustion engine having a dedicated EGR cylinder; the dedicated EGR cylinder comprising a direct injector; a controller structured to interpret a warmup condition, and in response to the warmup condition to provide a warmup operation command; and the direct injector being responsive to the warmup operation command. 2 . The system of claim 1 , wherein the dedicated EGR cylinder is a selective…
