ABSTRACT:
The disclosure describes a high-temperature optical transducer capable of acquiring input variables for closed-loop control of combustion systems. The key components of the innovation are a high-temperature, embedded photodiode, the use of low-cost, integral absorption filters; and the use of an embedded high-temperature preamplifier circuit. These components are combined in an optical-to-electrical signal transducer deployed in the high-temperature combustion environment, thus avoiding the high costs of optical signal transmission. The optical signals to the transducer are employed to recognize events in real-time such as the ignition spark, the start of combustion, end of combustion, misfires, and knocking. The outputs from the transducer may be used in a statistical fashion to control engine roughness and cyclic stability. By resolving specific colors in the flame, the optical sensors may also be used to determine the temperature and the emission production in the combustion chamber.
