Abstract
An exhaust arrangement for a multi-cylinder internal combustion engine of a vehicle which has a row of cylinders. The arrangement includes an exhaust manifold including a branch portion having a plurality of branch pipes corresponding to the cylinders, a catalyst disposed downstream of the exhaust manifold, and an exhaust pipe connecting the exhaust manifold to the catalyst. The exhaust pipe defines an exhaust path having a bend. The bend includes a plane dividing an interior of the bend into equal halves. A partition divides the exhaust path into first and second exhaust passages coextending in a longitudinal direction of the exhaust pipe. The partition extends in the bend in alignment with the plane. An oxygen sensor is disposed at the bend of the exhaust pipe in alignment with the partition and projects into both of the first and second exhaust passages through a periphery of the partition.
