This project, CRC E-90-2b, was conducted by Southwest Research Institute (SwRI) in order to assess the impact of E10+ blends on MIL illumination and exhaust emissions compliance. The original objectives of this study were to: (1) Document the change in fuel trim and other engine parameters as vehicles operate on a range of ethanol fuels under real-world conditions. (2) Determine if the MIL would illuminate and/or diagnostic trouble codes (DTCs) would be set on potentially sensitive vehicles when exposed to E15 and/or E20. (3) 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.
