Spark Plug Temperature Measurement by using an IR Camera

Abstract

The technique to measure spark plug temperature in an engine combustion chamber was developed. As for this technique, the infrared image of a spark plug in a visualization engine is captured with an IR camera. The visualization window which stands up to the environment of the combustion chamber which reaches 100 atm and 2000°C is attached, and this technology can measure a plug temperature to drive in the high load. Furthermore, this technology can measure a change in plug temperature in every cycle.
