Abstract
Disclosed is an exhaust-gas after-treatment device for an internal combustion engine, in particular for a ship's diesel internal combustion engine that is operated with heavy oil, including: a housing through which exhaust gas flows; exhaust-gas purification chambers formed in the housing, which chambers hold catalysts and/or particulate filters in order to purify the exhaust gas; and muffler chambers formed in the housing, which chambers have a defined depth for muffling sound in the flow direction. The exhaust-gas purification chambers and the muffler chambers are arranged spatially in series and parallel to one another on the flow side.
