Conceptual schematic of direct thermoelectric generator mounted in a vehicle’s exhaust stream. The exhaust energy content of Atkinson-cycle engines, which are used in many hybrid powertrains, is lower than conventional IC engines due to the cycle’s inherently higher thermal efficiency. Indirect configurations are also possible.

of the energy output of the fuel is used to actually move the car; the rest is wasted. Of the energy output of fuel in a car engine, 33% is spent in exhaust, 29% in cooling and 38% in mechanical energy, of which friction losses account for 33% and air resistance for 5%. With current technology, only 21.5% million TJ/a.

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. dCi (type K9K) diesel is the brand’s best-selling engine with almost 900,000 units manufactured in 2009, in Valladolid (Spain) and Bursa (Turkey).

BMW is looking into ways to maximise waste heat recovery in vehicles with two pathways being explored - thermoelectric and thermodynamic. At the SAE 2009 World Congress, it presented an analysis of two basic configurations of the Rankine cycle applied to a thermodynamic heat recovery system in a four cylinder combustion engine.

The fuel flow rate of the new ICE must not exceed 100 kg/hour; this maximum rate can only be achieved above 10,500 rpm. A sole single-stage compressor and single-stage exhaust turbine are used for pressure charging. Energy losses in the gearbox can also have a significant impact on fuel economy. Turbocharger.

This makes it possible for the waste heat from the electrical drive components to be made available to the interior of the Q7 e-tron quattro. For example, fuel economy statistics and a graphic display of the electric range is shown on the navigation map. There is a separate cooling circuit for cooling the fuel cell.
