Flame-Temperature Measurements in Internal-Combustion Engines

Abstract

The theory, development, and calibration of an electro-optical pyrometer, capable of determining instantaneous true temperatures of luminous flames, are described. A description is also given of auxiliary apparatus used with the electro-optical pyrometer to obtain simultaneous values of pressure, temperature, and crank position in an internal-combustion engine. Typical data obtained with this instrumentation as applied to a Diesel engine are included.
