    摘要: A sensor having electrodes connectable to an AC or DC voltage for powering an electrical discharge such as a corona, glow, arc, or the like. Additional electrodes connectable to analysis voltage may be proximate to the discharge providing electrodes. The discharge may ionize a sample fluid of varying chemical composition, flowing through a channel where the electrodes are situated. The discharge may be part of a group of sensors sensing the fluid flowing from a particle filter, gas chromatograph (GC) separator, thermal conductivity detector (TCD), optical sensors, photo ionization detector (PID), and to additional micro discharge devices (MDDs) and a mass spectrometer and/or a processor for analysis and processing to obtain results and information about the sample fluid composition.

    摘要: A method for determining the type of fuel used by a vehicle includes receiving hydrocarbon speciation and nitrogen-oxygen compound data from an emissions sensor. The hydrocarbon speciation data is compared to one or more hydrocarbon threshold levels, and each threshold level corresponds to an anticipated fuel type. The nitrogen-oxygen compound data is compared to one or more nitrogen-oxygen compound threshold levels, and each threshold level corresponds to an anticipated fuel type. Based on the comparison of the hydrocarbon speciation and nitrogen-oxygen compound data to threshold levels, an anticipated fuel type is determined.
