Abstract
Means and methods are provided for determining the energy content of a hydrocarbon fuel by infrared spectroscopy. The relationship between the energy content of the fuel and the number of carbon-carbon and carbon-hydrogen bonds in the fuel is disclosed. This relationship is utilized to determine the energy content of the hydrocarbon fuel by measuring the concentration of such carbon-carbon and carbon-hydrocarbon bonds by infrared spectroscopy. A first embodiment irradiates a hydrocarbon fuel with infrared radiation of wavelengths at which specific carbon-carbon and carbon-hydrogen bonds strongly absorb. A detector array and microprocessor process the data to compute the energy content of the fuel or rate of energy consumption by a device using the fuel. A second embodiment exposes the hydrocarbon fuel to infrared energy by using frustrated total internal reflection.
