    • An on-board gas composition sensor is disclosed for monitoring oxygen content levels in the exhaust gas of an internal combustion engine. The gas composition sensor includes a light source for generating excitation light, e.g. in the 350-525 nm wavelength range. A sensor body of porous high-temperature fluorescent inorganic oxide ceramic exposed to the exhaust gas emits an optical fluorescence signal responsive to oxygen content in the exhaust gas upon exposure to the excitation light at 400.degree.-650.degree. C. A florescence detector receives the optical fluorescence signal from the sensor means and generates an exhaust gas oxygen content output signal in response. Fiber-optic cable can be employed for transmitting excitation light to the sensor body from a remotely located light emitter. The same or a separate fiber-optic cable can transmit the optical fluorescent signal from the sensor body to the fluorescence detector also at a remote location.
    • 公开了一种用于监测内燃机的废气中的氧含量水平的车载气体组成传感器。 气体成分传感器包括用于产生激发光的光源,例如 在350-525 nm波长范围内。 暴露于废气的多孔高温荧光无机氧化物陶瓷的传感器体在暴露于400-650℃的激发光时,响应于废气中的氧含量发射光学荧光信号。荧光检测器接收光学 来自传感器装置的荧光信号,并且响应地产生排气氧含量输出信号。 可以使用光纤电缆将激发光从远程位置的发光器传输到传感器主体。 相同或单独的光纤电缆也可以在远程位置将光学荧光信号从传感器主体传输到荧光检测器。
