Abstract
A method of controlling preselected parameters in an engine powered by a fuel mixture of first and second liquids utilizes differing dielectric constants of the first and second liquids to alter the frequency of an oscillator using a tank circuit formed by an inductor coil immersed in the fuel mixture and the distributed capacitance of the coil. The frequency of the oscillator therefore can be used to determine the percentages in the fuel mixture of the first and second liquids. The percentages, in turn, are used to control the preselected engine parameters.
