Abstract
A plural fuel system for internal combustion engines in which the efficiency of the engine is raised by burning fuels singly or in combination with other liquid, gasified, or gaseous fuels, which best meet the load, speed, and environmental demands placed on the engine. A microprocessor-controlled air compressor adjusts the volume of air entering the engine cylinders, adjusting the effective compression ratio and charge density of the engine in accordance with the fuel or fuels being burned, while maintaining precise air/fuel ratios. Environmental conditions such as air temperature, altitude, coolant temperature, etc. are also sensed, processed, and adjusted by the microprocessor through various input and output devices in real time. The substitution of gasoline by natural gas or methane generated from organic wastes will reduce by a factor of 30%-70% the consumption of gasoline, reduce engine wear and auxiliary pollution control devices, make refueling a more flexible process by charging through home gas lines, and increase engine performance under all conditions.
