Abstract
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.
