Downsizing, Exhaust, Range and Waste

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

Green Car Congress

OCTOBER 10, 2012

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.

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. or so, according to Thomas, resulting in the total possible benefits ranging from about 6% to 17%.

Alcohol-based transportation fuels from a wide range of biomass feedstocks including agricultural, forestry, municipal and industrial waste and specially grown crops and trees can potentially offer a substantial substitute for oil derived fuel. More modest downsizing up to 5 liters could offer a practical solution.

Cobra could enable a 5–10% reduction in CO 2 emissions when implemented in conjunction with engine downsizing and down speeding strategies, and potentially more when used in conjunction with alternative fuels, according to CPT. Unlike a turbocharger, Cobra is not dependent on the exhaust gases flowing to do its work.

The low voltage approach compared with full hybrid and EV nominal voltages, which are typically in the range of 300 to 600V, avoids the need for high cost safety features and large battery packs. Moreover, compared with other electrical machines they have a high efficiency across a large speed range, good controllability, and reliability.

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.
