Ducted Combustion Systems Utilizing Curved Ducts

摘要

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 a plurality of orifices, the plurality of openings injecting fuel into the combustion chamber as a plurality of fuel jets. The system includes a duct structure defining a plurality of curved ducts and disposed within the combustion chamber between the flame deck surface and the piston top surface, the plurality of ducts being disposed such that each of the plurality of fuel jets, at least partially, enters one of the plurality of ducts upon being injected into the combustion chamber.
