Abstract
An exhaust muffler disposed in proximity to a cylinder of a general-purpose engine is provided, in which an exhaust muffler for a general-purpose engine is formed from a muffler main body connected to a cylinder of a general-purpose engine via an exhaust pipe and disposed adjacent to the cylinder, a partition member that divides the interior of the muffler main body into a first muffler chamber communicating with the exhaust pipe and a second muffler chamber communicating with an exhaust outlet of the muffler main body, and an exhaust cooling pipe exposed outside the muffler main body while providing communication between the first muffler chamber and the second muffler chamber. This enables exhaust gas to be cooled effectively by passing though the exhaust cooling pipe when moving from the first muffler chamber to the second muffler chamber, thus enhancing muffling by reducing the pressure of the exhaust gas.
