ABSTRACT:
A muffler for internal combustion engines to afford a better approach to the solution of air pollution problems due to unburned fuel fractions. The muffler is of the catalytic type and has a flattened structure, with the flow of the exhaust gases through the catalyst taking place in a substantially downward vertical direction. By such an arrangement the gas pressure drop through the catalyst is reduced and the catalyst efficiency is increased.
