FUEL INJECTOR IN AN ENGINE HAVING SPRAY ORIFICE SET CONFIGURED FOR OFFSET POSITIONING AND ENGINE OPERATING METHOD

An engine includes a piston movable in a cylinder and having a combustion bowl, and an annular rim forming a scoop extending axisymmetrically around a piston center axis. A fuel injector tip extends into the cylinder and includes a first orifice set and a second orifice set offset from one another and offset from the piston center axis. A plurality of orifice-rim distances are defined between orifices in the second orifice set and an annular rim of the piston. The orifices in the second orifice set having a range of orifice sizes varied in direct relation to the respective orifice-rim distances. Related methodology is also disclosed.
