BMW Outlines Intelligent Heat Management Applications for Reducing Fuel Consumption and CO2; New Thermoelectric Generator Unit Integrated with EGR

Green Car Congress

Making some of that waste heat energy available through intelligent heat management offers significant potential for reducing fuel consumption and CO 2 emissions, BMW said. This method of maintaining temperatures is equally suited for all kinds of vehicles and in all climate zones, although it is somewhat more effective at low temperatures.
