Top Ten Blendstocks For Turbocharged GasolineEngines

Bio-blendstocksWith Potential to Deliver the for Highest Engine Efficiency

Highlights of the Report:

• A tiered process efficiently and effectively screened hundreds of blendstocks.
• Ten blendstocks were identified with the potential to increase engine efficiency by 10 percent using the efficiency merit function.
  • i-ButanoloCyclopentanone
  • Di-isobutylene
  • EthanoloFuran mixture
  • Fusel alcohol mixture
  • Methanol
  • Prenol
  • i-Propanol
  • n-Propanol
• Six of the blendstocks were determined to have the fewest barriers to adoption and use.
• The blendstocks all have the potential to reduce life-cycle greenhouse gas emissions by at least 60 percent.
• The top 10 blendstocks were all determined to have the potential to be produced at a competitive cost.
• Co-Optima researchers identified barriers to adoption and key research gaps to be addressed in future research
