Abstract

An exhaust manifold (4), which is joined to a catalyst container (3) for accommodating a catalyst (2) with a tilt angle, includes: a plurality of branch pipes (6a, 6b, 6c, 6d) communicating with corresponding discharge ports (E1, E2, E3, E4) of an engine; an exhaust collecting portion (7) where the plurality of branch pipes are collected; and a partition plate (8) dividing the interior of the exhaust collecting portion (7). The partition plate (8) is cut away to provide a cut (9) at an end surface portion (8A) located toward the catalyst (2).

Claims

1. An exhaust manifold which is joined to a catalyst container for accommodating a catalyst with a tilt angle, comprising:

a plurality of branch pipes communicating with corresponding discharge ports of an engine;

an exhaust collecting portion where the plurality of branch pipes are collected; and

a partition plate dividing an interior of the exhaust collecting portion,

wherein the partition plate is cut away at an end surface portion located toward the catalyst.

2. An exhaust manifold according to claim 1, wherein a sensor is provided at the cut-away portion of the partition plate.
