Abstract: An exhaust manifold is disclosed. The exhaust manifold includes a plurality of exhaust tubes connected to one another, such that a male connector portion of one exhaust tube is received into a female connector portion of an adjacent exhaust tube. The plurality of exhaust tubes define an exhaust passage therein. The exhaust manifold also includes an air shielding zone surrounding the plurality of exhaust tubes. The exhaust manifold further includes a cooling jacket. The cooling jacket surrounds the air shielding zone. A high temperature seal is disposed within the air shielding zone. The high temperature seal is positioned outside of an interface area of the male and female connector portions of the respective exhaust tubes. The high temperature seal is configured to separate the air shielding zone into regions. Also, the high temperature seal is configured to control fluid communication between the separated regions of the air shielding zone.

Abstract translation: 公开了一种排气歧管。 排气歧管包括彼此连接的多个排气管，使得一个排气管的阳连接器部分被容纳在相邻排气管的阴连接器部分中。 多个排气管在其中限定排气通道。 排气歧管还包括围绕多个排气管的空气屏蔽区。 排气歧管还包括冷却套。 冷却套围绕着空气屏蔽区。 高温密封件设置在空气屏蔽区内。 高温密封件位于各排气管的阳连接器部分和阴连接器部分的界面区域的外侧。 高温密封件构造成将空气屏蔽区域分离成区域。 此外，高温密封件构造成控制空气屏蔽区域的分离区域之间的流体连通。
