Abstract: A method for operating an air intake system for an engine is disclosed. The air intake system includes an air filter configured to provide filtered air to the engine for combustion. The method includes activating a blower, by a controller, to generate suction and draw purged contaminants from the air filter for facilitating a purging of the air filter. The method further includes deactivating the blower, by the controller, upon a determination of a completion of the purging of the air filter.

Abstract: System and method for controlling a transmission in response to transient torque events are disclosed. The method includes commanding a maximum transmission output torque; comparing the commanded output torque to a feedback torque to determine if they are equal; and incrementally increasing the transmission output torque until equal. A machine and a powertrain include a controller configured to command a maximum negative transmission output torque in response to a transient torque event, and incrementally increase the transmission output torque until such time as the transmission output torque is equal to or within a preset range of the feedback torque.

Abstract: An air system and method includes an air compressor, a temperature sensors, a valve, and a controller. The air compressor is configured to receive filtered air. The temperature sensor is positioned at or near an outlet of the air compressor and configured to sense a temperature at or near the outlet of the air compressor. The valve is operatively connected to an outlet of the air compressor and external to the air compressor. The controller is configured to monitor the sensed temperature at the outlet of the air compressor and control the valve to permit air to flow from the outlet of the air compressor through the valve to unload the air compressor if the sensed temperature exceeds a threshold temperature.

Abstract: The present disclosure relates to an exhaust scavenging system for an engine system including an engine enclosed in an engine enclosure and an air intake system including an air filter having a filter element for filtering air. The exhaust scavenging system includes an exhaust conduit, a venturi, and a valve system. The exhaust conduit is coupled to the engine and is configured to receive exhaust gas discharged by the engine. The venturi is associated with the exhaust conduit and operates to generate a suction to draw air from the air filter and the engine enclosure. The valve system is configured to selectively fluidly connect the venturi with the engine enclosure or the air filter. The valve system fluidly connects the venturi with the air filter for facilitating purging of the filter element of the air filter.

Abstract: A transmission system is disclosed for use with an engine. The transmission system may have a plurality of gear sets, an input member configured to be powered by the engine and to drive the plurality of gear sets, an output member driven by the plurality of gear sets, and at least one clutch configured to selectively engage select gears of the plurality of gear sets. The transmission system may also have a controller in communication with the engine. The controller may be configured to generate an estimated temperature of the at least one clutch. The controller may further be configured to selectively derate the engine based on the estimated temperature.
