ABSTRACT:
An apparatus and method for automatically reducing engine exhaust noise from a dump truck including a heated bed without the additional requirement of diverting the flow of exhaust through a separate muffler apparatus. An engine noise reduction system associated with the truck includes an engine control unit for controlling high idle engine speed parameters of the truck engine. When the truck bed is raised upwardly from an initial lowered position to release a material load from the bed, or hydraulics associated with the truck bed are actuated to raise the bed, the engine control unit automatically lowers the high idle engine speed of the truck engine to reduce engine noise from the truck engine. The high idle engine speed of the truck engine is automatically reset to the standard setting when the truck bed returns to the initial lowered position.
