Beschreibung
Zusammenfassung:	An exhaust purification device of a multi-cylinder engine which improves exhaust gas purification performance by substantially uniforming a flow rate of exhaust gas throughout a treatment carrier such as a catalyst and improving dispersibility of the exhaust gas from the multi-cylinder engine to the catalyst and other components in the exhaust purification device wherein two collecting pipes are arranged at substantially symmetric positions across a partition plate part, which has a linear cross sectional shape, and is arranged centrally between the pipes which are each formed into D-shaped cross sectional shapes and comprise a first straight line part, a pair of second straight line parts connected with respective ends of a first straight line part and arranged to be substantially parallel with each other, and a circular arc part that connects ends of a pair of second straight line parts on opposite sides of the first straight line part.
