Higher-Cetane Diesel, Higher-Octane Gasoline Could Aid CAFE, CO2 Limits

摘要

Car electrification (full or partial), natural gas and cellulosic ethanol can seem to dominate today’s discussions about ways to cut North American vehicle carbon-dioxide (CO2) emissions and oil import dependence. But the automotive and fuels industries could be overlooking two relatively cheap, alternative ways to help accomplish those same goals, without any new fuels infrastructure or big powertrain costs: boost gasoline octane and diesel cetane.
