Abstract

A kind of catalystic converter, it comprises at least one catalystic loader (2, 3) to provide cleaning exhaust gas flow (1) of unregulated exhaust system from a small-size engine (10), its characteristics is the catalystic converter has at least a first stage (2) and a second stage (3), therein the incoming secondary air (4) between the effluent of inlet of the fist stage (2) and the outlet of the second stage (3) serves as the zone for preliminary cleaning execution.
