Abstract

Muffler with catalytic converter (1) essentially arranged in direct connection with a combustion engine's exhaust port and especially intended for portable working tools such as chain saws. At least one partition (2) is embodied in the muffler, or instance in the form of a baffle (3), and the partition (2) comprises one or several apertures (9, 10), through which the exhaust flow passes in order to flow from one side of the partition to the other side, and the partition is at least partly coated with a catalyzing layer.
