Abstract: A fuel injector includes an injector housing having a fuel connector, and an outer housing surface extending around a longitudinal axis of the injector housing. The outer housing surface includes a cylindrical upper section, a cylindrical lower section, and a middle section. The fuel connector defines a connector axis oriented normal to a longitudinal axis of the injector housing and extending between a first connector end attached to the middle section, and a terminal connector end radially outward of the outer housing surface and having therein a fuel inlet. The fuel connector includes an outer connector surface having an unthreaded base section, and an externally threaded end section adjacent to the terminal connector end.

Abstract: A fuel injector assembly includes a fuel injector defining a longitudinal axis extending between a first axial injector end, and a second axial injector end. The fuel injector further includes, between the first axial injector end and the second axial injector end, a first clamp face and a second clamp face defining a middle plane. The fuel injector assembly further includes a clamp having a forked injector portion forming a slot receiving the fuel injector and in contact with each of the first clamp face and the second clamp face, and a bolting portion having a bolt hole formed therein. The bolt hole defines a bolt hole axis oriented parallel to the longitudinal axis and offset from the middle plane.

Abstract: A fuel injector includes an injector housing defining a longitudinal axis extending between a first axial injector end and a second axial injector end. The injector housing includes an upper body piece forming the first axial injector end and including a fuel connector defining a connector axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. An injector full diameter (FD) is defined by the upper body piece. An axial distance (AD) is defined between an intersection of the connector axis and the longitudinal axis, and the nozzle terminal tip. A ratio of AD to FD is from 4.8 to 5.1.

Abstract: A fuel injector includes an injector housing defining a longitudinal axis, and including a body piece having formed therein a fuel inlet defining a transverse axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. The injector housing further includes a locating surface axially inward of the nozzle terminal tip and extending circumferentially around the nozzle. A first axial distance (AD) is defined between an intersection of the transverse axis and the longitudinal axis, and the nozzle terminal tip. An exposed tip length axial distance (TL) is defined between the locating surface and the nozzle terminal tip. A ratio of AD to TL is from 8.06 to 8.34.

Abstract: A power system may include a high-speed flywheel connected to an engine of a machine; a battery; a motor-generator unit (MGU) connected to the engine and the battery; and a turbocharger connected to the engine. One or more of the high-speed flywheel, the battery and the MGU, or the turbocharger may be configured to provide supplemental power to power provided by the engine to operate the machine, or provide replacement power when no power is provided by the engine to operate the machine.

Abstract: A controller may identify a plurality of sets of potential parameters associated with operation of an engine, wherein each set of potential parameters includes a potential setting of a turbine of a variable geometry turbocharger (VGT) of the engine and a potential setting of an intake throttle valve (ITV) of the engine. The controller may determine, based on the plurality of sets of potential parameters, a plurality of sets of predicted values, wherein each set of predicted values includes a predicted outlet pressure of a compressor of the VGT and a predicted temperature of an exhaust gas of the engine. The controller may determine respective scores of the plurality of sets of predicted values, and may select, based on the respective scores, a particular set of predicted values of the plurality of sets of predicted values. The controller may thereby control the turbine of the VGT and the ITV.

Abstract: A cylinder head includes a cylinder head casting having four gas exchange openings formed in a fire deck. A bolt bore and a glow plug bore extend through the cylinder head casting between an upper surface and a lower surface. The four gas exchange openings are arranged at twelve o'clock, three o'clock, six o'clock, and nine o'clock positions, circumferentially around an injector bore center axis. The bolt bore is positioned angularly between the twelve o'clock position and the three o'clock position, and the glow plug bore is positioned angularly between the three o'clock position and the six o'clock position.
