Induction control for direct injected engine

摘要

A direct injected, internal combustion engine combustion chamber configuration that employs a shrouded arrangement for the intake valve seat so as to generate a tumble motion under at least some running conditions. This is accomplished by a shrouding of the intake valve in such a way that the flow direction effects a tumbling motion and also so that the air flow does not adversely affect the flow from the injector nozzle.
