The prototype motor runs on that blend without thought for any further after treatment. The project
was intended to try and determine what possibility if any existed to go beyond Tier 4 without some
massive mechanical intervention. Adding the ethanol helped to emissions issue but now you've got
two fuels though the onboard mix isn't a huge issue. Project is an end around to try and bring
some sense into the "what's next" argument ie whatever is next might be so expensive to operate
that the minor reduction in emissions isn't worth the financial hit.
