Ford Conducts Design of Experiment Investigating Thermoelectric Energy Regeneration

Green Car Congress

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.

liter engine, a hybrid system, a Waste Heat Recovery (WHR) system, along with a number of other upgrades. The Freightliner SuperTruck features a low-back-pressure, next-generation aftertreatment system that efficiently removes NO x from the exhaust stream. This reduces friction, and increases efficiency and fuel economy.
