Abstract
Exhaust emissions are reduced, fuel consumption is improved for internal-combustion engines, and the number of cold starts reduced by storing heat energy from the operation of the engine in a heat-storage reservoir filled with a change-of-state heat-storage material. Absorbed heat energy is released back to the engine's intake manifold to maintain elevated engine temperature between uses and starting up of the engine.
