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

Green Car Congress

The remaining two-thirds are lost as waste heat going into the environment through the car’s exhaust emissions and through the radiator. 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.
