ABSTRACT:
A defroster assembly uses heat from an engine's exhaust to heat the exterior of a windshield and the wipers thereon. The assembly comprises an air intake mechanism shared with the engine's air filter. The air intake mechanism leads to air ducts spaced from the engine block. Nodes in the air ducts encircle exhaust outlet pipes leading from the engine so that heat of the engine exhaust is transferred to air in the ducts. The assembly includes a vent subassembly for directing a stream of air in a laminar flow along the windshield. A fan of the assembly draws air from the ducts and forces it through the vent subassembly.
