WASTE HEAT TO POWER SYSTEMS - US EPA

Although not technically an engine component or function, waste heat recovery systems attempt to regain some of the 50% or so lost thermal efficiency from the fuel used in the engine. Waste heat recovery systems are more sophisticated than the simple exhaust gas boiler or economizer and the heat can be used in variety of ways.
