Methods and apparatus for vaporizing and utilizing fuels of various octane ratings

Abstract

Modifications to the cylinder head of internal combustion engines in which the efficiency of fuel combustion is raised by the use of a plurality of liquid, vaporized liquid, and gaseous fuels through the alteration of cylinder compression ratios and spark timing to burn those fuels. It has been demonstrated that certain fuels have salient advantages under specified engine speed and load conditions, and in selected enviroments and vehicle applications, but that no single fuel is capable of excelling in all potential application scenarios. Burning each of these fuels efficiently has required engine specifications optimized to a single fuel or fuel state, such as compression ratio, intake tract design, electronic fuel injector duration and timing, and spark timing curves, which have been severely compromised when they were required to cope with the demands of a second fuel. The solutions demonstrated seek to show how these past compromises may be eliminated or minimized to enable the singular and simultaneous use of selected fuels to increase performance, reduce combustion pollutants, and increase the engine life of internal combustion engines. In addition, many of the possible alternate fuels which may be adapted to this proposal are in abundant domestic supply, and would reduce the undesirable economic effects which accompany large-scale petroleum imports; the consequential balance of trade deficits, dependence on volatile foreign sources,and vunerable tanker fleets and refining facilities.
