Title: Ducted combustion systems utilizing duct-exit tabs

Abstract

A ducted combustion system is disclosed. The ducted combustion system includes a combustion chamber bound by a flame deck surface of a cylinder head of an internal combustion engine and by a piston top surface of a piston disposed within the internal combustion engine. The system includes a fuel injector including one or more orifices, the one or more orifices injecting fuel into the combustion chamber as at least one fuel jet. The system includes at least one duct disposed within the combustion chamber between the flame deck surface and the piston top surface, the at least one duct including one or more structural tabs proximate to an outlet of the at least one duct and being disposed such that the at least one fuel jet, at least partially, enters one of the at least one duct upon being injected into the combustion chamber.
