A method and device for raising the temperature of exhaust gas from an engine by increasing parasitic loading on the engine without significantly increasing engine speed. This may be accomplished by increasing a demand on a hydraulic fan powered by a variable displacement hydraulic pump and meeting the demand by adjusting the displacement for the variable displacement hydraulic pump.

Increased fan speed to assist DPF regeneration

A method for controlling an engine in a work machine includes determining a base engine operating limit; determining a hydraulic system load on the engine; calculating a modification value for the base engine operating limit; generating a modified engine operating limit based on the modification value and the base engine operating limit; generating an engine control signal based on the modified engine operating limit; and transmitting the engine control signal to operate the engine at the modified engine operating limit to thereby supply additional power from the engine to the drive train to at least partially compensate for the hydraulic system load.

Work machine, control system and method for controlling an engine in a work machine

A work machine comprises an external housing, an air precleaner, an air filter, and a plenum box. The air precleaner is positioned outside the external housing, and the air filter is positioned inside the external housing. The plenum box is coupled fluidly to the air precleaner and the air filter for communication of intake air from the air precleaner to the air filter through the plenum box.
