Abstract: Operating a dual fuel engine system includes igniting a main charge of gaseous fuel in response to combustion of an early pilot shot of liquid fuel and production of a spark. Operating the system also includes covarying a spark timing parameter and a pilot shot delivery parameter, and reducing an error in a phasing of combustion of another main charge based on the covarying of the spark timing parameter and the pilot shot delivery parameter.

Abstract: A gaseous fuel engine system includes an engine housing forming a plurality of intake ports, and a plurality of fuel admission tubes oriented to admit a gaseous fuel into the plurality of intake ports. The fuel admission tubes include mixers having flow-impinged surfaces exposed to at least one of a flow of gaseous fuel or a flow of intake air and each including a detachment edge. The mixers may include fins, wedge structures, and/or a contoured outer surface of the fuel admission tube. Related apparatus and methodology is also disclosed.

Abstract: An internal combustion engine includes a cylinder case forming a cylinder bore having a centerline and an inner bore surface. A piston disposed within the cylinder bore forms a crown surface. A region defined between the piston and the cylinder bore in a radial direction has an annularly shaped mouth opening surrounding the crown surface. A cylinder head is disposed to cover an open end of the cylinder bore such that a variable volume is defined within the cylinder bore between the cylinder head and the piston. The cylinder head also forms a flame deck in fluid contact with the variable volume. A deflector structure forms a portion of the inner bore surface adjacent the flame deck surface, and is disposed between the flame deck and a topmost ring seal groove of the piston when the piston is at a TDC position.

Abstract: A liquid fuel injector such as for a dual fuel system in an internal combustion engine includes two-way injection control valves for controlling twin outlet checks. A first set of orifices are arranged in an A-F-Z pattern, and a second set of orifices are arranged in an A-F-Z pattern, within the fuel injector, among a high-pressure inlet passage, a low-pressure space, and first and second outlet check control chambers, respectively. A common nozzle supply cavity is fluidly connected to the high-pressure inlet passage and supplies each of two sets of nozzle outlets opened and closed by the twin outlet checks.
