Abstract
An exhaust gas muffler for an internal combustion engine, especially the engine of a manually-guided implement such as a power saw, a cut-off machine, or the like. The muffler has a housing having an inlet for exhaust gases and an outlet out of the housing. The housing has an outer wall over which the exhaust gases from the outlet flow. To achieve an adequate cooling of the exhaust gas muffler and the discharging exhaust gases, the exhaust gases out of the outlet draw in atmospheric air between the exhaust gases and the outer wall of the housing.
