PERFORMANCE OF EXHAUST SILENCER COMPONENTS

PART OF A SYSTEMATIC INVESTIGATION AIMED AT PRODUCING MORE ACCURATE THEORETICAL MODELS FOR INTERNAL COMBUSTION ENGINE EXHAUST SILENCERS IS DESCRIBED. THE PERFORMANCE OF A NUMBER OF SILENCER COMPONENTS, E.G. AREA DISCONTINUITIES, BRANCHED SYSTEMS, WAS MEASURED IN A VERY NOISY EXHUAST SYSTEM. THESE RESULTS WERE THEN COMPARED WITH THOSE PREDICTED BY THE ONE-DIMENSIONAL LINEARIZED THEORY WITH MEAN GAS FLOW. IT WAS FOUND THAT THIS ONE-DIMENSIONAL THEORY WAS SUFFICIENTLY ACCURATE FOR SILENCER DESIGN PURPOSES. /AUTHOR/
