Spark-excited fluorescence sensor

摘要: A spark-excited fluorescence sensor (10) is provided, which enables monitoring of various gas species (14), such as H2, COx, NOx, O2, N2, NHx and hydrocarbons added to a system source fuels and/or additive agents, or discharged from exhaust including pollutants, for more efficient use optimizing performance the system, and, also, reducing pollutants in atmosphere. The invention comprises spark plug (12) excite molecules gaseous species, an optical fiber window (18) bundle (20) collect transmit, respectively, fluorescence, bandpass filters (24) select predetermined wavelengths corresponding gases be detected, detectors (26), signal processor (28). output then used improve overall system.
