WIPO Patent Application WO/2010/125660

Kind Code:

A1

Abstract:

Provided is an internal combustion engine (1) equipped with an exhaust manifold (10) having: a plurality of branch pipes (11a-11d), a manifold body (12) to which the branch pipes (11a-11d) are connected on the exhaust downstream side of the branch pipes (11a-11d), and a wall (15) that is provided on the inside of a manifold body (12) so as to divide the interior space of the manifold body (12) into a first space (S1) comprising connecting sites (111a-111d) to which the branch pipes (11a-11d) are respectively connected, and a second space (S2) that does not contain the connecting sites (111a-111d). A first and a second supply pipe (16, 17) connect a first outer wall (13) of the manifold body (12) that forms the first space (S1) to a low pressure stage turbine (LT) and a high pressure stage turbine (HT) respectively. A first and a second discharge pipe (18, 19) connect a second outer wall (14) of the manifold body (12) to the two turbines (LT, HT) respectively. An exhaust pipe (20) is connected to the second outer wall (14).
