Method for extending the lower lean limit of running of internal combustion engines and improving the combustion of fluid fuels

摘要

A fuel composition is disclosed comprising a major portion, in the order of 94% by weight, of a liquid fuel such as gasoline mixed with a minor portion, in the order of 6% by weight, of particulates generally similar to particulates of polyvinyl alcohol of about 10 to 40 microns in size. These particulates are suspended in and are small enough to be metered along with the liquid fuel in a conventional automobile carburetor and when this fuel composition is burned in the combustion chamber of internal combustion engines, the particulates function as nuclei for droplets of the carrier fuel which act as combustion promotion agents in the dry vapor charge at the instant of combustion to intensify the burning process to extend the low lean limit of consistent and regular engine firing and to reduce NO.sub.x. A similar composition of liquid fuel in open flame combustion results in a much improved heat transfer efficiency of the energy in the fuel.
