摘要： A method and apparatus for determining a volatility of a fuel sample. A fuel sample is collected in a container and heated for a time period using a heater device. Periodically during the heating, the capacitance of the fuel sample and the temperature of the heater device are determined. After a time period passes, the volatility of the fuel sample is determined using the capacitance decrease and the temperature increase. Specifically, a voltage across the heater device is used, along with the current through the heater device to determine the resistance of the heater device, which gives the temperature of the heater device and the sample. The capacitance and temperature are compared to values derived from experimentation for fuels of varying DI. The first measurement of capacitance with a known sample volume can be used to determine the MTBE or ethanol content in gasoline fuels.

The capacitance electrodes include interdigitated electrodes and fuel traps for containing a sample of liquid fuel disposed between the interdigitated electrodes. The dimensions of the fuel traps are selected so that the fuel traps remain filled with liquid after said sensor has been bathed in fuel.

摘要： A gas sensor for sensing NOx having electrochemical cells wherein dielectric material surrounds electrolytes except where electrodes are attached. Thereby, the exhaust gas is effectively prevented from contacting the electrolytes of the sensor's electrochemical cells. With the use of this technique, signal cross talk is minimized while enhancing NOx sensing sensitivity. Further, the total number electrodes needed are reduced which allows for more complex sensors structures.
