Fuels for internal combustion engines

Abstract

Mixed alcohols can be used as a fuel additive in gasoline, diesel, jet fuel or as a neat fuel in and of itself. The mixed alcohols can contain C1-C5 alcohols, or in the alternative, C1-C8, or higher, alcohols in order to boost energy content. The C1-C5 mixed alcohols contain more ethanol than methanol with amounts of propanol, butanol and pentanol. C1-C8 mixed alcohols contain the same, with amounts of hexanol, heptanol and octanol. A gasoline-based fuel includes gasoline and the mixed alcohols. A diesel based fuel includes diesel and the mixed alcohols. A jet fuel includes kerosene and the mixed alcohols. The neat fuel of the mixed alcohols has an octane number of at least 109 and the Reid Vapor Pressure is no greater than 5 psi. The gross heat of combustion is at least 12,000 BTU's/lb.
