装置。 In an exhaust gas purification device in which a catalytic converter is provided in each exhaust passage connected to each of the front and rear cylinder rows of a horizontal V-type internal combustion engine, both the catalytic converters are disposed at the front of the engine, and exhaust gas is discharged from the rear cylinder row. The upstream side of the catalytic converter for the rear cylinder row, into which exhaust gas is guided, and the downstream side of the catalytic converter for the front cylinder row, into which exhaust gas discharged from the front cylinder row is led, are communicated via a bypass passage, and the front side An exhaust gas purification device characterized in that a bypass control valve is provided on the downstream side of the cylinder row catalytic converter to allow exhaust gas flowing out from the front cylinder row catalytic converter to flow into the bypass passage only when the engine is warmed up. .
