ABSTRACT:
A method of operating an engine is provided. The engine includes operating a cylinder with net exhaust flow from the exhaust manifold, through the cylinder, to the intake manifold. Concurrently, another cylinder may operate to carry out combustion with net flow from the intake to the exhaust. In this way, exhaust in the intake manifold may be adjusted by varying valve operation of the first cylinder.
