摘要

A silencer which may be arranged in place in an exhaust system of an internal combustion engine includes walls forming the main body of the silencer; a first separator supported by the walls to define a rear chamber therebetween; a second separator supported by the walls to define a first intermediate chamber between the walls and the first and second separators; a flame-extinguishing device supported by the walls to define a second intermediate chamber in combination with the walls, the second separator and the flame-extinguishing device as well as to define a front chamber between the walls and the flame-extinguishing device; an inlet pipe in fluid communication with the front chamber whereby an exhaust gas may flow from the inlet pipe into the front chamber; an outlet pipe in fluid communication with the first intermediate chamber whereby the exhaust gas may flow out of the first intermediate chamber through the outlet pipe; and an inner pipe having a plurality of apertures formed therein.
