ABSTRACT:
A method of real-time analysis of an engine, comprising sensing a temperature within a chamber of the engine with a thermocouple sensor disposed on a spark plug operating within the chamber, the thermocouple sensor generating a first signal based upon the temperature within the chamber; detecting current on a wire coupled to the sparkplug with a sensor, the sensor generating a second signal based upon current detected on the wire; converting the first and second signal into a first and second optical signal respectively utilizing one or more signal conditioners; generating a first and second digital signal based upon the first and second optical signal respectively with a receiver; and transmitting the first and second digital signal to an analysis device to generate a display of the temperature as it relates to engine speed at a first time in response to the receipt of the first and second digital signal.
