ORNL Researchers Find Thermochemical Exhaust Heat Recuperation In Internal Combustion Engines Could Provide Substantial Boosts in Second-Law Efficiency

Green Car Congress

Methanol can be converted directly to syngas by adding heat alone in the presence of a catalyst; other fuels, such as ethanol and isooctane, require additional oxygen or water for complete conversion to syngas. We therefore considered it important to include the expected changes in combustion exergy losses as part of our analysis.
