ABSTRACT:
An apparatus is provided which utilizes the heat of fusion of a storage material to store heat from a vehicle exhaust system for later use in warming the lubricant or cooling fluid of the engine. An elongated canister has a portion of the exhaust system running through it, and that portion is located near the bottom of the canister. Located in the top of the canister is a heat exchanger through which flows engine coolant or lubricant. The remainder of the canister is filled with a heat storage material which may consist of various eutectic salt mixtures or single salts having temperatures of fusion and heats of fusion such that the material is in a liquid state when warmed by the exhaust system and in a solid state at ambient temperatures.
