Abstract: A system may determine that an upcoming pass is a final pass associated with loading a machine. The system may compute, based on determining that the upcoming pass is the final pass, a trigger time associated with causing a trigger signal to be transmitted. The trigger time may be computed based on a final pass completion time that identifies a time at which the final pass is expected to be completed. The trigger time may be prior to the final pass completion time. The system may cause the trigger signal to be transmitted at the trigger time. The system may cause, based on a receipt of the trigger signal, a transition of the machine from an idle state to a ready state to be initiated. The transition from the idle state to the ready state may be caused to be initiated prior to a time at which the final pass, associated with loading the machine, is completed.

Abstract: A sealing face defined at a mating surface of a component is disclosed. The sealing face includes a first slant surface extending inwardly from a top edge of the mating surface to a first inner edge of the component. The first slant surface is disposed at a first angle with respect to the mating surface. The sealing face further includes a straight surface extending from the first slant surface. The straight surface is provided between the first inner edge and a second inner edge of the component. The sealing face further includes a second slant surface extending inwardly from the straight surface to an innermost edge of the component. The second slant surface is disposed at a second angle with respect to the straight surface.

Abstract: An engine system includes an electronically controlled compression ignition engine configured to burn diesel fuel and a high ash oil to produce an exhaust with a temperature and NOx to soot ratio as well as a controlled level of ash deposits on the particulate filter of the system. An aftertreatment system is fluidly connected to the engine and includes a diesel oxidation catalyst, a reductant supply, and a diesel particulate filter coated with a NOx reduction catalyst. The soot load density on the diesel particulate filter can be stabilized by oxidizing soot at about a same rate as the compression ignition engine is supplying soot to the aftertreatment system.
