Exhaust Heat Recovery using Electro-Turbogenerators 2009-01-1604

Reciprocating engines remain the dominant power plant for both vehicles and power generation up to a few MW. Yet, circa 30% of the energy in the fuel is lost through the exhaust system. In today's market, it has become essential to attempt to recover some of this “wasted energy” and put it to good use. Exhaust Heat Recovery (EHR) systems are playing an increasingly important role in the Emissions and Fuel Consumption challenges facing today's Heavy Commercial Vehicle (HCV), Off-Highway and PowerGen markets globally. This paper puts forward an argument in favour of Electro-Turbocompounding as a system that is technically mature enough to benefit the above markets today.
