Abstract
A muffler for internal combustion engines having the interior of an expansion chamber sectioned by a porous plate through which an exhaust inlet pipe is extended. The inlet pipe is closed at its down-stream end and is provided with many perforations in that part of the inlet pipe positioned in the expansion chamber. Such perforations permit the inlet pipe to communicate with the interior of the expansion chamber in the muffler.
