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.

Claims (35)

1. 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.

2. The method as in claim 1 , wherein the one or more signal conditioners are each in signal communication with the receiver through a fiber optic cable.

3. The method as in claim 1 , wherein the first digital signal includes combustion temperature data and the second digital signal comprises engine speed data.

4. The method as in claim 1 , wherein the engine speed is measured in revolutions per minute.

5. The method as in claim 1 , wherein the receiver includes a plurality of channels configured to receive one or more optical signals.

6. The method as in claim 1 , wherein the receiver includes a first connector, the first and second digital signals are transmitted to the analysis device through the first connector.

7. The method as in claim 1 , wherein the receiver generates a first and second analog signal based upon the first and second optical signal respectively, the first analog signal includes combustion temperature data and the second analog signal includes engine speed data.

8. The method as in claim 7 , wherein the receiver includes a second connector, the first and second analog signals are transmitted to an analog device through the second connector.

9. The method as in claim 1 , wherein the analysis device is configured to correct the combustion temperature of the first digital signal with a predetermined correction factor, the predetermined correction factor is based upon an expected combustion temperature.

10. The method as in claim 9 , wherein the analysis device transmits the corrected combustion temperature to a storage device of the receiver.

11. The method as in claim 1 , wherein the receiver is configured to correct the combustion temperature of the first digital signal with a predetermined correction factor prior to transmitting the first digital signal to the analysis device, the predetermined correction factor is based upon an expected combustion temperature.

12. The method as in claim 1 , wherein the generation of the visual display is updated at least approximately once per second and the generation of the visual display is generally instantaneous with the generation of the first and second signal.

13. The method as in claim 1 , wherein the visual display includes a table or chart demonstrating combustion chamber temperatures as they relate to engine speeds over a predetermined period of time.

14. A method of real-time analysis of an engine in operation, 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 by a receiver, the receiver configured to correct the combustion temperature of the first digital signal with a predetermined correction factor; and

transmitting the first and second digital signal to an analysis device, the analysis device is configured to generate a visual display of the corrected 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.

15. The method as in claim 14 , wherein the predetermined correction factor is based upon an expected combustion temperature.

16. A real-time engine analysis system, comprising:

a thermocouple sensor disposed on a spark plug operating within a combustion chamber of the engine, the thermocouple sensor is configured to generate a first signal based upon a combustion temperature within the chamber;

a current sensor disposed proximate to an electrical power connection of the spark plug, the current sensor is configured to monitor electrical current on the electrical power connection and generate a second signal based upon current detected on the electrical power connection;

one or more signal conditioners configured to generate a first and a second optical signal based upon the first and second signal respectively;

a receiver electrically connected to the first signal conditioner and the second signal conditioner, the receiver is configured to generate a first and a second digital signal based upon the first and second optical signal respectively; and

an analysis device in signal communication with the receiver, the analysis device configured to receive the first and second digital signal and 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.

17. The system as in claim 16 , wherein the one or signal conditioners are each in signal communication with the receiver through a fiber optic cable.

18. The system as in claim 16 , wherein the receiver is further configured to generate a first and second analog signal based upon the first and second optical signal respectively.

19. The system as in claim 18 , wherein the receiver includes a first connector and a second connector, the first and second digital signals are transmitted to the analysis device through the first connector and the first and second analog signals are transmitted to an analog device through the second connector.

20. The system as in claim 16 , wherein the receiver is further configured to correct the combustion temperature of the first digital signal with a predetermined correction factor that is based upon an expected combustion temperature, the analysis device is configured to display the corrected combustion temperature as it relates with the engine speed at the first time through the visual display.
