摘要： Operating an internal combustion engine system includes feeding a stream of pressurized intake air to a plurality of cylinders in an engine for combustion with a methanol fuel. An engine parameter indicative of at least one of an exhaust NOx level or a change to the exhaust NOx level of the engine is monitored, and water injected into an intake conduit for the engine based on the monitored engine parameter to limit the exhaust NOx level of the engine. Related apparatus and control logic is disclosed.

摘要： A telehandler comprising: a chassis; an axle supporting the chassis; a pivotal connection between the axle and the chassis; and a chassis positioning system. The pivotal connection is configured to enable rotation of the chassis relative to the axle for varying a chassis-axle tilt angle defined between a longitudinal axis of the axle and the chassis. The chassis positioning system comprises: a chassis angle sensor configured to measure an angular position of the chassis relative to gravity; an actuator configured to rotate the chassis relative to the axle at the pivotal connection; and a control system configured, in a first mode, to control the actuator to thereby control the chassis-axle tilt angle based on the measured angular position of the chassis.

摘要： A system for communicating an impact sustained by a work machine moving at a worksite to a remote operator workstation for controlling the work machine through the remote operator workstation. The system includes a controller configured to obtain data associated with an acceleration of the work machine along one or more degrees of motion during a movement of the work machine at the worksite and derive an acceleration value based on the data. The controller is further configured to issue a notification of the impact of the work machine to the remote operator workstation through an output device of the remote operator workstation if the acceleration value exceeds a threshold acceleration value during the movement of the work machine.

摘要： A fluid system may include a first fluid circuit configured to circulate a first fluid to cool or heat a non-combustion power source of a machine. The first fluid circuit may include at least one of a refrigeration unit to cool the first fluid or a heating unit to heat the first fluid. A cooling capacity of the refrigeration unit may exceed a cooling requirement of the non-combustion power source, or a heating capacity of the heating unit may exceed a heating requirement of the non-combustion power source. The fluid system may include a second fluid circuit configured to circulate a second fluid. The fluid system may include a heat exchanger in the first fluid circuit and in the second fluid circuit. The heat exchanger may be configured to cool or heat the second fluid using the first fluid.

摘要： A method of operating a cable handling system of a longwall mining machine having a shearer movable along a pan line to mine material along a mine face, the cable handling system including:
i) a service line configured to carry one or more supply lines to the shearer for facilitating shearer operation,
ii) a plurality of interconnected trays to accommodate the service line,
iii) a plurality of sensor nodes distributed along a length of the service line, and
iv) a plurality of transceivers distributed along a length of the pan line, the method comprising:
a) sensing orientation, acceleration and/or position data of the service line using the plurality of sensor nodes,
b) using the plurality of transceivers to receive the orientation, acceleration and/or position data from the plurality of sensor nodes and to transmit the orientation, acceleration and/or position data to a controller, and
c) detecting, by the controller, an actual or imminent failure mode of the service line using analysis of the orientation, acceleration and/or position data from the plurality of the sensor nodes.-

摘要： Techniques to limit electrical power when forming an electrical grid using an active front end unit having an inverter that is coupled to a capacitor (and inductor) that is coupled to an electrical grid. For example, to limit power, the integration of a commanded frequency of the system can be limited to be within a specified phase delta of a measured phase angle of an electrical grid voltage vector. The calculation from power limit to phase delta can be done when the phase of the electrical grid voltage vector has been determined to be accurate and is calculated based on the measured capacitor voltage, grid voltage, and the estimated voltage drop across the output components of the system.

摘要： A track roller includes a body having a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes a first rim portion disposed proximate to the first axial extremity, and a second rim portion disposed proximate to the second axial extremity. An outboard track contact surface is disposed axially proximate to the first rim portion, and an inboard slot is disposed axially proximate to the second rim portion.

摘要： A system may determine configuration information associated with a power system for a work site that includes one or more power sources. The system may determine respective operation parameters of the one or more power sources and one or more performance criteria associated with the power system. The system may determine a baseline operation plan for the power system. The system may identify an optimization analysis technique and may process, using the optimization analysis technique, the configuration information associated with the power system, the respective operation parameters of the one or more power sources, and the one or more performance criteria associated with the power system to generate the optimized operation plan for the power system. The system may cause, based on the baseline operation plan for the power system and the optimized operation plan for the power system, one or more actions to be performed.
