can't quite see ethanol being able to replace diesel or biodiesel, but would be interesting to see them apply it to lighter duty applications. I found another site that explored the small motors with compression ignition and turbo's with ethanol, and at higher rpm's, it came out better. I just can't see it in a heavy duty application though. PDF file: http://www.ifp.fr/IFP/fr/IFP02OGS.nsf/0/A035F6E8F33537C880256F94003B7A09/$file/jeuland1_vol59n6.pdf?openelement
