摘要： An exhaust device for a 2-cycle engine including an exhaust pipe having an expanded portion, and a curved outlet pipe inserted in the exhaust pipe in such a manner that its one end opening is disposed in a position in the expanded portion in which the output power loss of the expanded portion can be decreased and its the other end opening is disposed at one side of the exhaust pipe. The use of a curved pipe as an outlet pipe enables the outlet pipe to be positioned such that its one end opening is disposed in a suitable position in the expanded portion while its the other end opening is disposed at one side of the exhaust pipe, thereby allowing the outlet pipe to have a suitable length and the volume of the resonance chamber in the exhaust pipe to be increased.
