Abstract
THIS paper outlines a new method of measuring end-gas temperatures within the cylinder of an operating engine. The new instrument measures the acoustical properties by the pulse method, transmitting an acoustical impulse through a gas path of known length and measuring the time of propagation through the gas. The method yields a value for the average velocity of sound in the path.
The authors describe the instrument and engine modifications necessary. The results of tests are also discussed, with a detailed description of one series.
The appendixes outline the mathematical steps of finding the sound velocity in gas mixtures and the fuel-air cycle for the detailed series of tests.
