Abstract

A work machine, such as a tractor or skid steer, has a motion sensor attached to a segment of a continuous ground-engaging track in its undercarriage. The motion sensor generates motion data indicative of a change in motion for the track segment as the track rotates around a track assembly. An electronic controller for the work machine receives and evaluates the motion data, first to identify a location of the track segment within the undercarriage and then to compare the motion data with expected motion data for the track segment under normal track tension. Motion data outside a range of the expected motion data indicates an abnormal sag in the track, causing the electronic controller to generate an alert for adjustment of the track tension.

Abstract

Described herein are systems, methods, and other techniques for performing an alignment operation concurrently with a retraction operation at a construction machine. A guidance line is set for guiding an implement of the construction machine. An input signal is received via a user input device for moving the construction machine to reduce an extension distance between the implement and the machine's platform. A first control signal is generated to cause a movement of the construction machine to reduce the extension distance. During the movement of the construction machine, a second control signal is generated to cause the machine's boom to horizontally rotate with respect to the platform such that the implement moves along and remains aligned with the guidance line.

Abstract

Traditionally, diesel exhaust fluid (DEF) injection rates in aftertreatment systems for diesel engines must be restricted at low temperatures to prevent urea crystallization at and beyond the point of injection. Urea crystallization can reduce the amount of diesel exhaust fluid that can be injected, decrease the efficiency of nitrogen-oxides (NOx) reduction process, and the like. Disclosed embodiments utilize a catalyst material upstream from the point of injection to convert urea into ammonia, prior to injection. This eliminates or reduces urea crystallization at and beyond the point of injection.

Abstract

An internal combustion engine (100) system is described herein. The system uses a reactor (120) to create pilot fuel (112) from the primary fuel (104) to assist in the ignition of the primary fuel (104). The system uses one or more heaters to increase the temperature of the primary fuel (104) to an operational temperature of a reactor (120) used to convert the primary fuel (104) in a dehydration reaction. The heaters use waste heat generated by the operation of the engine (102). The waste heat can be lubricant used to remove heat from components of the engine (102) as well as heat from the exhaust of the engine (102), for example. A controller (146) is used to maintain an operational range of a level of the pilot fuel (112) in an accumulator (114). The accumulator (114) acts as a buffer to allow the engine (102) to continue to receive the pilot fuel (112) during dynamic and changing conditions of the engine (102).

A mechanical swing brake variable control system for an earth-moving machine including an upper revolving car body with swing components mounted on the upper revolving car body, a lower traveling car body with traction components mounted on the lower traveling car body, and a mechanical service brake interconnected with the upper and lower car bodies, controls relative rotation between the upper and lower car bodies. A pressure control device controls a variable pressure applied to the mechanical service brake to vary an amount of swing drive holding torque. An electronic controller monitors and processes signals received from sensors associated with the swing components and machine operator commands, and variably controls the amount of holding torque exerted on the upper revolving car body using the mechanical service brake as a function of one or more of machine roll angle, operational configuration of the swing components, inertial mass of the swing components, and machine operator commands.

Abstract

Overheating of the rollers in a track on mobile equipment can result in failure of the track. Accordingly, embodiments are disclosed for a temperature monitoring device (300) that can be installed within an oil fill hole (214) of each roller (200). Each temperature monitoring device (300) may monitor the oil temperature within a respective roller (200), and communicate that oil temperature or other temperature indication to a controller (130). The controller (130) may alert a human operator or another system when the temperature of a roller (200) exceeds a predefined threshold that is indicative of overheating.

Abstract

A locomotive propelled by a hybrid power system includes a boost mode of operation accessible on-demand by the operator. When a throttle (304) is set to deliver maximum power from a diesel-electric engine, an operator can select actuators (314,320,324) separate from the throttle (304) to request that a control module deliver additional electrical power from batteries. The actuators may be soft keys (312) or a touchscreen on a computer monitor (310) or mechanical switches (324) as part of the locomotive cab. The actuators (314,320,324) provide boost notches (TN 9 B, TN 10 B, TNI IB) of additional power beyond the typical eight notches the throttle (304) at least for transient conditions, and existing locomotives may be easily and inexpensively retrofitted with the actuators.

Abstract

A combined heat and power system for generating power using a hydrogen internal combustion engine and producing usable heat from the exhaust gases of the hydrogen internal combustion engine is described. The system includes a heat exchanger and reduction device, such as a catalytic converter. The heat exchanger may extract heat from the exhaust gases upstream of the catalytic converter and thereby control the heat of exhaust gases provided to the catalytic converter for reduction of exhaust gases. The catalytic converter may use hydrogen as a reducing agent, thereby using the same fuel source for powering the engine and reduction of the exhaust gases rather than separate working fluids. The heat exchanger and/or operating parameters of the system may be controlled to control a temperature of exhaust gases at the catalytic converter and thereby control efficiency of the conversion of exhaust gases.

Abstract

A cab system for a work machine includes an operator cab and a platform. The platform is arranged adjacent to the operator cab. The platform includes support members arranged one after the other in a linear array. Each support member is inclined with respect to a thickness direction of the platform to deflect a material spray coming off from one or more of the traction devices of the work machine during a movement of the one or more traction devices. Also, each support member defines a clearance with respect to an adjacent support member to allow see-through visibility through the platform from a portion associated with the operator cab.
