Abstract: A nozzle for a fuel injector is disclosed. The nozzle may have a body having a base end, a tip end, and a central bore extending from the base end to the tip end. The nozzle may also have a sac located within the central bore at the tip end. Further, the nozzle may have an orifice located within the tip end and in communication with the sac. The orifice may be skewed at an azimuthal angle relative to a radial direction of the central bore.

Abstract: A piston for an engine is disclosed. The piston may include a piston crown, and a piston bowl recessed within the piston crown. The piston bowl includes a center portion, a cone portion, and an annular toroidal portion. The geometry of the piston bowl is designed to correspond with a fuel injection nozzle having a specific spray angle. An exemplary piston bowl may include a toroidal major diameter between about 4.645 and 4.895 inches and a toroidal minor radius between about 1.165 and 1.235 inches. The cone portion includes an angle between about 26 to 34 degrees. The compression ratio of the piston is about 17.95 to 1.

Abstract: A turbocharger mixing manifold for an exhaust aftertreatment system for a two-stroke locomotive diesel engine providing for a transition of a non-uniform exhaust gas flow field exiting a turbocharger into a regulated, uniform exhaust gas stream with minimal aerodynamic losses and an even distribution (mixing) of hydrocarbons in liquid, gas or burning states in order to ensure optimal performance of the attached exhaust aftertreatment system.
