Measurement of combustion chamber surface temperatures is
necessary for many areas of engine research. These authors require
surface temperature data for a study on thermal barrier coatings
(TBCs) in an aluminum alloy spark-ignition (SI) engine. For many
years, the thermocouple has been the sensor most commonly used
to measure surface temperatures. However, there is no consensus
about the optimal thermocouple design or even general configuration
that best suits fast response engine applications.
