摘要

In the method exhaust gas is led to flow in an exhaust gas passage, which has a first pipe (10) and a second pipe (16) surrounding the first pipe. The exhaust gas is led to flow so that the exhaust gas flows through the first pipe to the first direction and through the second pipe to the second direction opposite to the first direction. In the space between the first pipe and second pipe at least a part of the exhaust gas flow is brought to the rotating and advancing flow. The arrangement in the exhaust gas passage comprises a first pipe (10), which has a first opening (12) and a second opening (14), and a second pipe (16), which at least partly surrounds the first pipe. The second pipe has a first end (18) and a second end (20). The first end of the second pipe has an end plate (24) closing the second pipe. The arrangement further comprises at least one flow guide (36) in the space between the first pipe and the second pipe for bringing at least a part of the exhaust gas to be led to the first pipe to the rotating and advancing flow.
