PERFORMANCE PREDICTIONS OF RESONATOR MUFFLERS

Measurements were made of the performance of a number of resonator mufflers inserted in turn in the exhaust system of a six-cylinder two-stroke diesel engine which developed approximately 200 horsepower. An axial traverse was made of the pressure fluctuations within the muffler and for a distance of about 2 feet 0 inch on either side of it. Narrow-band analysis of these pressure fluctuations revealed a series of standing wave patterns from which the overall behavior of the muffler could be determined and compared with the predicted performance.
