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.

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: In one aspect, a method for controlling an internal combustion engine system including an exhaust gas recirculation (EGR) valve and a variable-geometry turbocharger (VGT) having a compressor and a turbine includes receiving a plurality of requests for the internal combustion engine system. The method also includes predicting a plurality of expected states of the internal combustion engine system based on the plurality of requests and generating sets of candidate control points for actuating the EGR valve and the VGT based on the plurality of expected states. The method further includes selecting a set of candidate control points that avoids a surge condition of the compressor and based on the selected set of candidate control points, generating commands for actuating the EGR valve and the VGT.

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 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 system for uniform flow distribution of a reductant is disclosed. The system includes an injector lance and a diffuser assembly. The injector lance further includes a reductant supply conduit and an injector lance. The reductant supply conduit extends into an internal diameter of an exhaust conduit from a first end of the exhaust conduit towards a second end of the exhaust conduit. The injector lance is in communication with and extends perpendicular to the reductant supply conduit. The injector lance is located along a longitudinal axis of the exhaust conduit. The diffuser assembly is further collocated or integral with the injector lance.

Abstract: An aftertreatment brick can be installed in a brick compartment of an aftertreatment module with a releasable securing assembly. The releasable securing assembly includes a first bracket, a second bracket, and a band clamp. The first bracket is installed in the brick compartment proximate a port. The aftertreatment brick is placed on the first bracket adjacent the port and the second bracket is placed about the aftertreatment brick above the first bracket. The band clamp is slid over the first and second brackets and tightened to secure the brackets about the brick.
