20150240939 | System And Method For Controlling Transmission Of A Machine - A method of operating a machine having an engine and a transmission drivably coupled to the engine is provided. The method includes determining a power usage value of a work cycle of the machine based at least on a plurality of machine parameters and determining an operating cost map based at least on a fuel price and a Diesel Exhaust Fluid (DEF) price. The method includes determining a current operating cost based on the operating cost map and a current operating condition that is based on at least one of the machine parameters. The method includes determining a low cost operating condition corresponding to an operating cost less than the current operating cost. The low cost operating condition corresponds to a power of the machine that is greater than or equal to the power usage value. The method includes regulating the transmission to obtain the low cost operating condition. | 08-27-2015 |
20150258482 | CENTRALIZED PURGING UNIT FOR ENGINE SUB-SYSTEMS - A purging system for an engine system is disclosed. The engine system includes an engine and one or more to-be-purged sub-systems. The purging system includes a centralized purging unit with one or more compressed air sources to store and provide compressed air. The compressed air sources are fluidly communicable with each of the to-be-purged sub-systems. A control valve assembly includes one or more valves that are operably positioned between the compressed air sources and the to-be-purged sub-systems. A controller, which is in control communication with the control valve assembly, is configured to alternate the valves between an active state and an inactive state. This is to vary the fluid communication between the compressed air sources and at least one of the to-be-purged sub-systems. This alteration is based on a set of predefined threshold conditions. | 09-17-2015 |
20150354476 | Engine Adaptive Control Method to Optimize Exhaust Gas Recirculation and Intake Valve Actuation Events in Low Emission Diesel Engines - A power system may include an internal combustion engine, an exhaust gas recirculation system, a selective catalytic reduction system, and an engine control module. The internal combustion engine includes a plurality of combustion cylinders and a plurality of corresponding intake valves for controlling a flow of air from an intake into the cylinders. The engine control module is configured to adjust a closure timing of the intake valves based on at least one engine parameter and optimization of an operational cost of the power system. A method for controlling the power system may include recirculating a portion of an exhaust flow, injecting a reductant into the exhaust flow, and adjusting a closure timing of the intake valves based on at least one engine parameter and optimization of an operational cost of the power system. | 12-10-2015 |
20150369192 | Low Soot Dual Tip Variable Conicity Injector - A fuel injection apparatus for use in a compression ignition engine comprises a first injector tip defining a first set of outlet orifices therethrough and a second injector tip defining a second set of outlet orifices therethrough. The first set of outlet orifices has a first conicity and the second set of outlet orifices has a second conicity. The first conicity is different from the second conicity. | 12-24-2015 |
20160053676 | ASYMMETRIC TURBOCHARGER WITH VALVE ASSEMBLY - An asymmetric turbocharger of the present disclosure includes a turbine adapted to receive exhaust gas from an engine. The turbine includes a first volute, a second volute, and a valve assembly. The valve assembly includes a diaphragm to define a first chamber and a second chamber. The first chamber is adapted to receive compressed gas from the compressor and the second chamber is in fluid communication with the first volute. The valve assembly also includes a valve member disposed in the second chamber to cover an aperture of the second volute, against a force of a spring. The valve member is displaced when pressure of exhaust gas in the second volute is greater than a combined force of pressure of the compressed gas and the force of the spring. The exhaust gas enters the second chamber from the second volute to mix with the exhaust gas of the first volute. | 02-25-2016 |
20160057004 | SYSTEMS AND METHODS FOR MACHINE-TO-MACHINE AD-HOC COMMUNICATION - A method for dynamically establishing an ad-hoc network including a plurality of work machines includes receiving, by a communication module of a first work machine, a data packet, identifying an information type of the data packet, including determining, based on an information type identifier of the data packet, whether the data packet includes one of a first information type or a second information type, processing the data packet based on the information type identification, and forwarding the processed data packet a second work machine. The forwarding includes forwarding the data packet at one of a first rate or a second rate based on the categorization of the data packet into the first type of information or the second type of information. | 02-25-2016 |
