Patent ID: 8006545

Claim:
A method of real-time analysis of an engine, comprising: sensing a combustion 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 combustion temperature within the chamber; detecting current on an electrical power connection to the spark plug with a current sensor, the current sensor generating a second signal based upon current detected on the electrical power connection; converting the first and second signal into a first and a second optical signal respectively utilizing one or more signal conditioners; generating a first and a 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, the analysis device is configured to generate a visual display of the combustion temperature as it relates to an engine speed of the engine at a first time in response to the receipt of the first and second digital signal.
