Abstract:
1. A method of comparing a permeation emission for an alternative energy fuel to another alternative energy fuel or a fuel that is not an alternative energy fuel comprising: measuring a permeation emission obtained from operation of a fuel system on an alternative energy fuel comprising butanol at approximately sixteen percent (16%) by volume; measuring a permeation emission obtained from operation of a fuel system on another alternative energy fuel comprising ethanol at no more than about ten percent (10%) by volume; measuring a permeation emission obtained from operation of a fuel system on a fuel that is not an alternative energy fuel; comparing the permeation emissions obtained from operation of the fuel system on the alternative energy fuel comprising butanol, the alternative energy fuel comprising ethanol, and the fuel that is not an alternative energy fuel to evaluate whether the permeation emissions obtained from the operation of the fuel system on the alternative energy fuel comprising butanol contains permeation emissions equal to or less than the permeation emissions obtained from the operation of the fuel system on the alternative energy fuel comprising ethanol or the fuel that is not an alternative energy fuel.
