Abstract:
1. A direct injection compression ignition internal combustion engine, comprising: an engine housing defining a cylinder; a piston movable between a bottom dead center position and a top dead center position within the cylinder; and a fuel system including a fuel supply, and a fuel injector having an injector body defining a fuel inlet fluidly connected with the fuel supply, the injector body further having a nozzle extending into the cylinder and defining a nozzle supply passage configured to convey a fuel between the fuel inlet and a plurality of spray orifices formed in the nozzle and each defining a spray orifice center axis, wherein each spray orifice of the plurality of spray orifices has an inner diameter dimension in a direction normal to the corresponding center axis of about 0.09 millimeters or less, and wherein the plurality of spray orifices defines inter-orifice angles between adjacent center axes of about 36° or greater, such that spray plumes of injected fuel from each spray orifices of the plurality of spray orifices burn within the cylinder according to a non-sooting lifted flame and gas entrainment combustion pattern.
