Abstract: A ducted combustion system for an internal combustion engine includes a combustion chamber, a fuel injector, and a plurality of ducts. The combustion chamber is defined between a flame deck surface of a cylinder head and a piston crown of a piston disposed within a cylinder bore. Further, the fuel injector is configured to inject fuel into the combustion chamber as a plurality of fuel jets. The plurality of ducts is disposed within the combustion chamber between the flame deck surface and the piston crown. The plurality of ducts is disposed such that each of the plurality of fuel jets at least partially enters one of the plurality of ducts. The at least one of the plurality of ducts is configured to move to vary an angle of a corresponding at least one of the plurality of fuel jets relative to a longitudinal axis of the fuel injector.

Abstract: A liquid fuel injector for a fuel system in an internal combustion engine includes two injection control valves for controlling two outlet checks. A common nozzle supply cavity is fluidly connected to an inlet passage and supplies each of the two sets of nozzle outlets opened and closed by the outlet checks. A first nozzle outlet set forms a narrower spray angle and has a first combination of outlet number and outlet size, and a second nozzle outlet set forms a wider spray angle and has a second combination of outlet number and outlet size. The first nozzle outlet set has a greater steady flow than the second nozzle outlet set.
