  • CONCENTRATION DETECTOR AND METHOD OF USING THE SAME
    Publication number: 20070154352
    Abstract: A concentration detector is disclosed, which is adapted to sense the concentration of a liquid fuel and includes an internal compartment for containing the liquid fuel. The concentration detector comprises a heater, one or more temperature sensors and a concentration calculator. The heater is disposed in the internal compartment of the concentration detector to warm up the liquid fuel. The temperature sensors are disposed in the internal compartment of the concentration detector to measure the temperature of the liquid fuel. The concentration calculator is used to receive the temperature of the liquid fuel measured by the temperature sensors, to calculate a rate of change in the temperature of the liquid fuel, and then to compute a corresponding concentration of the liquid fuel based on the rate of change in the temperature of the liquid fuel.
