Infrared Study of a Piston Ring Temperatures in a Fired Engine

Abstract

Sapphire windows have been inserted in the liner of a Petter AV1 diesel engine to enable temperatures of piston lands and rings to be monitored during firing. The overall temperatures thus measured are comparable to those reported in the literature obtained using embedded thermocouples. However the very fast response time and surface specificity of the infrared method has also enabled transient temperature changes which take place just after ignition to be observed.
