The exhaust muffler, one of the important parts in the vehicle, is the essential device to reduce engine-induced noise. But it is very difficult to achieve listenable exhaust sound and it takes much time to tune inner structures of mufflers. In order to achieve harmonious exhaust sound quality, it is necessary to comprehend the sound characteristics of various inner structures (tube length, baffle location, etc) inside mufflers.
So, this study proposes muffler tuning kit as a practical new method possible to reduce tuning time and test sample numbers. First, we select muffler outer shape and volume as a original base muffler. Second, we design detail components of muffler(case, end plate-front/rear, tubes-inlet/middle/outlet and baffles). The tuning kit is designed to be possible to assemble, dissemble and change any components of different dimensions. Third we make tuning kit based on the preliminary detail design and compared exhaust noise in the engine bench with the original base muffler sample for NVH correlation.
As a result, exhaust noise of tuning kit is well matched with that of original base muffler sample. So we are expecting the tuning kit to be used to reduce tuning time and test samples of mufflers when developing new vehicle.
