Beschreibung
Zusammenfassung:	A power unit including a liquid-cooled engine, a radiator in fluid communication with the engine for cooling engine coolant, a fan on one side of the radiator for directing air therethrough, and a noise suppressing baffle on the other side of the radiator for altering the path of travel of air exiting the radiator and absorbing fan noise including a housing containing, noise suppressing material. The housing includes the improvement wherein a perforated panel faces the side of the radiator opposite the fan and is slightly spaced therefrom with the panel being pyramid-shaped and extending toward the radiator and presenting at least three generally planar surfaces intersecting at a common point to the radiator.
