TURBOCHARGER

A turbocharger (2) mounted on an engine (1) has an EGR pipe (11) through which part of exhaust gas (8) is extracted from an exhaust manifold (9) to be recirculated to a suction pipe (4), the exhaust manifold (9) being internally divided by a partition (14) for prevention of exhaust interference between cylinders (7). A turbine scroll (15) is internally divided, for continuity with an outlet flow path of the exhaust manifold (9), by a partition (16) such that one of the divided flow paths (A, B) by the partition (16) which served for extraction of the exhaust gas (8) to be recirculated is smaller in cross-sectional area than the other flow path which does not serve for extraction of the exhaust gas (8) to be recirculated.
