ABSTRACT:
Mufflers are provided for a vehicle exhaust system having a combustion chamber and an exhaust pipe. The vehicle exhaust system is configured to reduce the noise of combustion gasses generated in the combustion chamber. An exemplary muffler includes a proximal end and a distal end, the proximal end being configured for mounting the muffler to the exhaust pipe leading to the engine, the distal end being configured to allow the combustion gasses to pass therethrough, and at least one vortex chamber disposed between the proximal end and the distal end. The at least one vortex chamber includes a circular peripheral wall for inducing a vortex on a portion of the combustion gasses expelled from the combustion chamber during high-pressure pulsations created by the operation of a vehicle engine. The vortex impedes flow of the combustion gasses from the pipe such that acoustic energy associated with the expulsion of the combustion gasses is dissipated.
