Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord

Green Car Congress

Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power. An automotive TEG is intended to improve fuel economy by power from waste heat to reduce the electric generator load on the engine. down-speeding, downsized engine, etc.), W/cm 2 to 6.0

MAHLE-led consortium’s micro-CHP CNG engine provides 20% efficiency boost over current market best

Green Car Congress

CHP motors are a perfect solution for generating electricity and harnessing otherwise wasted energy for heating, for both primary power and heat generation or for use on an ad hoc basis during power outages. However, this technology has previously been cost prohibitive, inefficient and displayed suboptimal reliability characteristics.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

Because exhaust-driven reforming uses only waste engine heat, it avoids this efficiency hit, the authors note. Even with substantial reductions in exhaust line thermal mass, downsizing of the reformer is likely to be required to achieve heating times significantly below 5 min.
