Abstract: A control system for a machine having an engine, a first alternator, a second alternator, and an aftertreatment system is disclosed. The control system may include a sensor associated with the aftertreatment system and configured to determine a temperature of exhaust passing through the aftertreatment system, and a controller in communication with the sensor and connectable to the first and second alternators. The controller may be configured to determine an available power output of the first alternator, determine a load increase of the engine needed to raise the temperature of the exhaust to an operating temperature of the aftertreatment system, and selectively connect the first alternator to a power consumer to achieve the load increase when the available power output of the first alternator is greater than the load increase.

Abstract: An exhaust system for an engine having a throttle is disclosed. The exhaust system may include an exhaust passage connectable to the engine, a particulate filter disposed in the exhaust passage, a sensor configured to generate a signal indicative of a total pressure differential across the particulate filter caused by soot and ash accumulation, a load actuator configured to selectively adjust a load on the engine, and a control module electronically connected to the load actuator and the sensor.

Abstract: An aftertreatment control system for an engine is illustrated. The aftertreatment control system includes a first temperature sensor configured to generate a signal indicative of a temperature at an inlet of an aftertreatment system and a second temperature sensor configured to generate a signal indicative of an ambient temperature. The aftertreatment control system also includes a throttle position sensor configured to generate a signal indicative of a position of a throttle associated with the engine. The aftertreatment control system includes a controller coupled to the first temperature sensor, the second temperature sensor, the throttle position sensor, and the engine. The controller is configured to regulate, selectively, a power output of the engine based, at least in part, on the temperature at the inlet of the aftertreatment system, the ambient temperature, the position of the throttle, and a determined time period indicative of an operational time of the engine.

Abstract: An exhaust system for an engine is provided that may have an exhaust passage configured to direct exhaust from the engine to the atmosphere. The exhaust system may also have an aftertreatment component disposed within the exhaust passage, a throttle configured to generate a throttle position signal indicative of a throttle position of the engine, and a temperature sensor configured to generate a temperature signal indicative of the exhaust temperature. The exhaust system may also have a controller in communication with the engine, the throttle, the sensor, and the aftertreatment component, configured to monitor the temperature signal and track a total duration for which the temperature signal is less than a threshold temperature. The controller may also be configured to initiate a load increase on the engine to raise a temperature of exhaust exiting the engine when the total duration is greater than a threshold duration.

Abstract: A cooling control system is provided for a mobile machine having an engine. The cooling control system may have a circuit fluidly connected to the engine, and a heat exchanger configured to dissipate heat from coolant in the circuit. The cooling control system may also have a fan disposed proximate the heat exchanger, a thermostat configured to selectively allow coolant through the heat exchanger, and a locating device configured to generate a location signal indicative of a location of the mobile machine. The cooling control system may further have a pressure sensor configured to generate a pressure signal indicative of a barometric pressure in proximity to the mobile machine, and a controller in communication with the fan, the thermostat, the locating device, and the pressure sensor.

Abstract: A method of sharing power between locomotives in a consist may include receiving a power demand signal at a control computer on one of the locomotives, with the power demand signal indicative of a total power output requirement for the consist. The control computer may determine an amount of available power on an electrical power bus running through all of the locomotives in the consist, and the power generating capacity of all power sources that are electrically coupled to the electrical power bus. One or more power sources on any one of the locomotives in the consist may be activated to provide electrical power to the electrical power bus for use by a load on a different one of the locomotives in the consist.

Abstract: A control system for a locomotive having at least a first engine and a second engine is provided. The control system may include a controller in communication with the first engine, the second engine, and a throttle. The controller may be configured to start the first engine when the throttle is moved from an idle position to a first position and determine if the locomotive is operating in a yard mode or a line-haul mode. The controller may also be configured to start the second engine if the locomotive is operating in the line-haul mode and the throttle is moved from the first position to a second position and delay start of the second engine if the locomotive is operating in the yard mode and the throttle is moved from the first position to the second position.
