Exhaust manifold

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 ( 6 a , 6 b, 6 c, 6 d ) communicating with corresponding discharge ports (E 1, E 2, E 3, E 4 ) 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 ( 8 A) located toward the catalyst ( 2 ).

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.
