RUMBLE is a low-frequency noise heard in high compression engines and accompanied by high rates of pressure rise. Thus, rumble indicates a rapid combustion process. This paper describes a method of studying this problem: by detection of flame fronts by ionization gaps. Results of experiments show that rumble is caused by deposit ignition in the end-gas region. These multiple ignitions occur after the normal flame front has progressed partially across the chamber. The authors conclude that this type of deposit ignition is generally a self-sustaining process, lasting until the deposits are burned out at a particular engine performance level. When the level is increased, the process repeats itself.

TWO TEST TECHNIQUES are helping the muffler designer keep ahead of the growing demands on the muffler system — cold acoustical testing and resonant pipe sound velocity measurements. The first is a method of screening new configurations and the second a means of finding the velocity of sound of hot exhaust gases during a full-scale muffler test. The author discusses the design factors to be considered in designing mufflers, such as chamber location, resonators and multiple chambers and louvers; and the selection of the type of cross-section for the muffler.

The NET EMF of a thermoelectric circuit can be thought of as originating entirely in the regions of temperature gradient. Any extraneous materials, such as switch or connector terminals, in a temperature gradient may cause an error in the temperature measurement. In addition to circuitry errors, jet engine thermocouple indications require correction for the effects of conduction, radiation, response rate, and gas velocity. The magnitudes of the corrections depend on the thermocouple design and the environmental conditions. Performance curves for several typical jet engine thermocouples are presented, with the methods of making the various corrections.
