Abstract
A trailerable engine housing 10 for a heat and noise emitting engine 68 is provided, formed of an open topped container having pyramidally shaped end walls 22, 24, side walls 14, 16, and a base plate 42. The open topped container is divided into two separate enclosures by an enclosure baffle 58. A pair of vent panel 28, 30, are held in angled spaced relationship to the pyramidal side edges of the end walls to form an air induction vent hole open to one enclosure and a hot air exhaust hole open to the other. Inducted air is transferred from one enclosure to the other through an enclosure baffle vent hole. Sonic energy may not pass through either the induction air or the hot air exhaust vent holes without first being reflected off a surface within the engine housing.
