Abstract: A system for identifying an improper implement on a machine includes a machine configured for performing one or more tasks, the machine including: a movable link configured to change a position of an implement installed on the machine; a hydraulic system for moving the link, the hydraulic system including a hydraulic valve and a hydraulic pump; and a pressure sensor configured to detect a pressure of hydraulic fluid for the hydraulic system and output a signal according to the detected pressure. The system further includes a controller configured to receive the signal from the pressure sensor, determine that the implement is improper due to being oversized, overweight, undersized or underweight, based on the signal from the pressure sensor, and generate a notification in response to determining that the implement is improper.

Abstract: A work machine, such as an excavator or a backhoe, has a linkage of articulating arms for maneuvering a changeable work tool. Position and motion sensors and force sensors within the linkage provide data for a controller to determine a location of the work tool and down force applied from the linkage onto the work tool during a job. Before performing a grading operation, an operator may request level control for the work tool at a benchmark orientation and down-force control at a target down force. After a controller applies the target down force with the work tool at the benchmark orientation, an operator may traverse the work tool along a path radial to the work machine. While maintaining the benchmark orientation for the work tool, the controller may adjust one or more forces on the linkage to also maintain the target down force during the traversal of the work tool, leading to simpler functionality for the operator and higher quality work product.

Abstract: In some implementations, a controller may monitor, during a ramp up period of a fluid pump driven by a motor that is controlled by a variable frequency drive (VFD), an intake pressure of the fluid pump and a discharge pressure of the fluid pump. The controller may detect, based on monitoring the intake pressure and the discharge pressure, whether the intake pressure satisfies an intake pressure threshold or the discharge pressure satisfies a discharge pressure threshold. The controller may cause, via the VFD, reduction of a torque of the motor based on the intake pressure satisfying the intake pressure threshold or the discharge pressure satisfying the discharge pressure threshold.

Abstract: A piston may have an annular body including a crown portion defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, a plane containing the longitudinal axis and the radial direction, and a contoured combustion bowl. In the plane containing the longitudinal axis and the radial direction, the crown portion includes a radially outer squish surface, and a swirl pocket having a reentrant surface that extends axially downwardly and radially outwardly from the squish surface defining a tangent that forms a reentrant angle with the squish surface that ranges from 53.0 degrees to 57.0 degrees.

Abstract: A system can assign a machine to dispense material at designated areas along a route at a worksite. For example, the machine can be an electric water truck on a mine site, and the electric water truck can be assigned to spray water at areas along a route to control dust on the mine site. The system can verify that the machine is carrying enough material to dispense along the assigned route. The system can also verify that the battery of the machine is charged to a level sufficient to power travel of the machine through the assigned route and to power operations to dispense the material, based at least in part on a changing amount and/or weight of the material as the machine progresses along the route.

Abstract: A carbon capture system includes a hydrogen production module. The hydrogen production module is used to control the amount of hydrogen entering an internal combustion engine to reduce an amount of water vapor generated by the internal combustion engine, thereby increasing the efficiency of the carbon capture device. If too much water vapor is detected in an exhaust of the engine, the amount of hydrogen produced by a hydrogen production module can be increased, thereby reducing the amount of hydrogen entering the engine and reducing the amount of water vapor generated by the engine. A reformer catalyst can be used by the hydrogen production module to remove at least a portion of hydrogen in a fuel stream of the engine.

Abstract: The present disclosure relates to a composite fin structure for a radiator, comprising a plurality of elongated corrugated fins arranged in parallel and spaced apart from each other. Air flow channels are defined between the opposing main side surfaces of adjacent fins, allowing cooling air to flow therethrough along a longitudinal direction of the fins. It is characterized in that each fin comprises a first corrugated fin section having a first waveform and a second corrugated fin section having a second waveform, with extending directions of the first and second waveforms being consistent with the longitudinal direction of the fin. A fin density of the first waveform is greater than that of the second waveform, and the first corrugated fin section extend at least in an inlet side region of each air flow channel. This invention also relates to a radiator with the composite fin structure, as well as a fuel cell cooling system comprising the radiator.

Abstract: A center upper frame node connector, which can be a casting, can comprise: a forward horizontal upper frame node oriented in a first forward direction; a rearward horizontal upper frame node oriented in a first rearward direction opposite the first forward direction; a rearward angular upper frame node oriented in a second rearward direction and a first downward direction; a vertical upper frame node oriented in a second downward direction; and a first connection pad on a first side of the upper frame node casting and a second connection pad on a second side on upper frame node connector opposite the first side. The center upper frame node connector can be coreless, that is, without any hollow portions at any of the frame nodes and either of the first and second connection pads.

Abstract: An airbox includes an intake air inlet in a housing, wherein the intake air inlet includes a first portion and a second portion, at least one air outlet in the housing, and an air chamber within the housing and fluidly connected to the intake air inlet and the at least one air outlet. The air chamber includes an internal wall that divides the air chamber along an axis thereof into a first air chamber portion fluidly connected to the first portion of the air inlet and a second air chamber portion fluidly connected to the second portion of the air inlet, and a moveable air inlet damper configured to seal the first portion of the air inlet and occlude the first air chamber portion, or to seal the second portion of the air inlet and occlude the second air chamber portion.
