Exhaust Systems
fundamentals and design considerations
590064
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.
