Combustion engine with multi-fuel capability

Abstract From the Canadian patent

Abstract of the Disclosure, A combustion engine has apparatus effective to provide a fuel mixture of one or more liquid fuels such as gasoline of variable aromatic content normal, alcohols, cosolvents, octane improvers and hydrocarbons having different energy contents in an unknown combination and combine it with air in a controlled A/F ratio with an input from a fuel mixture dielectric constant sensor. The sensor comprises a capacitor in the fuel line near the engine so that the dielectric constant of the fuel mixture about to enter the engine determines the capacitance, a resistor in series with the capacitor, an oscillator providing an oscillating voltage across the resistor and …
