Design and Development of a Dielectric Sensor to measure the alcohol concentration on Flexible Fuel Vehicles

Abstract

A sensor was designed and fabricated for flexible fuel vehicles to detect the percentage of alcohol content in alcohol blend fuels. It works on the measurement of change in dielectric property of the ethanol-fuel mixture. Thus, sensor’s dielectric constant was measured and accordingly, the ethanol composition of the mixture was calibrated. This triggered the actuator to effect equilibrium in FFV vehicles. Compensating circuit was also developed to reduce the capacitor artifact errors and concurrently, increase the accuracy of the sensor. The accuracy of the sensor is relatively up to 2% and testing was carried out with the reference liquids as well as with different compositions of alcohol blend fuels.
