Abstract: A system for controlling operation of a winch assembly having an electric motor, a drum, and a cable. A controller is configured to access a winch load threshold, with the winch load threshold defining a hold zone and a reel zone, and one of the hold zone and the reel zone including loads greater than the winch load threshold and another of the hold zone and the reel zone including loads less than the winch load threshold. The controller is further configured to determine whether the drum is rotating, determine whether the winch assembly is operating within the hold zone or the reel zone, generate a hold current while the winch assembly is operating within the hold zone preventing rotation of the electric motor, and generate a reel current while the drum is operating within the reel zone permitting rotation of the electric motor.

Abstract: A visual indication system for a machine is provided. The visual indication system includes an output module configured to be displayed at an external location relative to an internal portion of a cabin of the machine and configured to provide a visual indication viewable. The visual indication system also includes a controller communicably coupled to the output module. The controller is configured to receive a signal indicative of a parking status and an implement status of the machine. Further, the controller is configured to determine a locked state associated with the parking status and the implement status. The controller is configured to transmit the visual indication of the determined locked state to the output module.

Abstract: An exhaust aftertreatment system including an exhaust conduit transmitting exhaust from an engine, a reductant introduction system introducing a reductant into the exhaust, and a selective catalytic reduction catalyst (SCR) receiving the exhaust and reductant. A SCR length divided by a SCR width is greater than 4. A SCR cell density is less than 180 cells per square inch of cross-sectional area of the SCR. The SCR is vertically mounted adjacent a corner of a cab of a machine.

Abstract: A homogeneous charge compression ignition engine is set up by first identifying combinations of compression ratio and exhaust gas percentages for each speed and load across the engines operating range. These identified ratios and exhaust gas percentages can then be converted into geometric compression ratio controller settings and exhaust gas recirculation rate controller settings that are mapped against speed and load, and made available to the electronic engine controller. This provides the engine controller with a look up table of what compression ratio and exhaust gas rates should be at each speed and load. The engine controller also balances at least one of combustion phasing and energy release among a plurality of cylinders in order to enable higher load operation.

Abstract: A multi cylinder homogeneous charge compression ignition engine includes actuators and an engine controller configured to reduce variations in combustion phasing and/or combustion energy release among the different engine cylinders. By sensing both the phasing and magnitude of the combustion energy release, the engine controller generates control signals to combustion phase controllers and combustion energy release controllers for the engine cylinders. The control signals may be different from one another to reduce variations across the group of engine cylinders. A combustion energy release controller may be a direct injection fuel injector, and the combustion phase controller may be a variable intake valve actuator. Reducing variations in these aspects of the combustion events, allows the engine to operate at higher speeds and loads.

Abstract: A homogenous charge compression ignition engine is operated by compressing a charge mixture of air, exhaust and fuel in a combustion chamber to an autoignition condition of the fuel. The engine may facilitate a transition from a first combination of speed and load to a second combination of speed and load by changing the charge mixture and compression ratio. This may be accomplished in a consecutive engine cycle by adjusting both a fuel injector control signal and a variable valve control signal away from a nominal variable valve control signal. Thereafter in one or more subsequent engine cycles, more sluggish adjustments are made to at least one of a geometric compression ratio control signal and an exhaust gas recirculation control signal to allow the variable valve control signal to be readjusted back toward its nominal variable valve control signal setting.

Abstract: A homogeneous charge compression ignition engine operates by injecting liquid fuel directly in a combustion chamber, and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine includes at least one turbocharger for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine are attained by throttling the fresh air inlet supply. These elevated exhaust gas recirculation rates allow the HCCI engine to be operated at higher speeds and loads rendering the HCCI engine a more viable alternative to a conventional diesel engine.
