Beschreibung
Zusammenfassung:	Disclosed are devices that include spark or particle arresting, features and muffler features. The disclosed devices may include: (a) an upstream inlet receiving exhaust gas flow; (b) a downstream outlet discharging exhaust gas flow; (c) a cylindrical body disposed between the upstream inlet and downstream outlet; and (d) a particle trap having an opening for collecting particulate matter in the exhaust gas flow, the particle trap disposed downstream of the cylindrical body on a wall of the device. The cylindrical body of the devices typically includes an annular channel permitting axial flow of gas therethrough from an upstream end of the annular channel through a downstream end of the annular channel. The downstream end of the annular channel may be configured to have openings for discharging exhaust gas flow and imparting a spiral flow to the discharged gas flow. As gas exits the annular channel, the particulate matter is forced radially outward via centrifugal force towards the wall of the device where the particulate matter is collected in the particle trap.
