Abstract
A ducted combustion system is disclosed. The ducted combustion system may include a combustion chamber, which is defined as an enclosure bound at a first end by a flame deck surface of a cylinder head of an internal combustion engine and bound at a second end by a piston top surface of a piston disposed within the internal combustion engine. The system may further include a fuel injector, having at least one orifice, injecting fuel into the combustion chamber as at least one fuel jet. The system may further include at least one Venturi duct disposed within the combustion chamber between the flame deck surface and the piston top surface, the at least one Venturi duct being disposed such that each of the at least one fuel jet, at least partially, enters the at least one Venturi duct structure upon being injected into the combustion chamber.
