ABSTRACT:
A ventilation system for a lightweight automobile having a plastic body includes a heating air inlet in fluid communication with fresh air at the engine hood upper cowl of the automobile. The air inlet is rigid plastic and is bonded to the hood to stiffen the hood. The fresh air is directed through the inlet to a heat exchanger shroud within the engine compartment, and the engine exhaust pipe passes through the shroud to heat the air in the shroud. From the shroud, the heated fresh air passes through a bulkhead valve into the passenger compartment, where it can be directed toward the passengers' feet or against the windshield to defrost the windshield. In addition, a rigid plastic fresh air plenum is transversely mounted in the passenger compartment as an instrument panel, and the fresh air plenum stiffens the body. Fresh air from the cowl is directed into the plenum and out of selectively coverable openings in the plenum to cool the passenger compartment.
