CRC E-90-2b was conducted by Southwest Research Institute (TradeName) (SwRI(TradeName)) to assess the impact of gasoline fuel blends greater than E10 on MIL illumination and exhaust emissions compliance. The objectives of this study are to: document the change in fuel trim and other engine parameters as vehicles operate on a range of ethanol fuels under real-world conditions; determine if the MIL will illuminate and/or Diagnostic Trouble Codes (DTCs) will be set on potentially sensitive vehicles when exposed to E15 and/or E20; determine if a vehicle with an illuminated MIL induced by E15 or E20 still meets its emission category target, using a standard cold-start FTP-75 test. One hundred and twelve vehicles meeting CRC specifications have been inspected and two hundred and thirteen vehicles have been screened. To date, seven vehicles have been selected by the CRC for evaluations in the program. This interim report contains results from evaluations of these vehicles. At the direction of the CRC, identification of the vehicles has been coded in the Phase 1 Results section of this report.
