前記ケーシングは、前記排気浄化部材を内部に保持する筒状の部材である内筒と、有底筒状の形状を有し且つ前記排気浄化部材の少なくとも一部を覆うように開口側の端部が前記内筒に外嵌する部材である外筒と、を備え、
前記ケーシングの内部において、
前記内筒の外周面と前記外筒の内周面との間の空隙である第１空間と、
前記内筒の端部と前記外筒の底部との間の空間である第２空間と、
が形成されており、
前記排気マニホールドの集合管の内部空間と前記第１空間とが前記外筒の側面に形成された開口部である流入口を介して連通するように、前記ケーシングと前記排気マニホールドとが接続されており、
前記流入口を介して前記集合管の前記内部空間から前記第１空間に向かって流入する排気の流れ方向への垂直投影図である第１投影図において、前記流入口の全体が前記内筒と重なっている、
ことを特徴とする、内燃機関の排気装置。 An exhaust system for an internal combustion engine, comprising an exhaust purification device including a casing and one or more exhaust purification members housed inside the casing, and an exhaust manifold,
the casing includes an inner cylinder which is a cylindrical member that holds the exhaust purification member therein, and an outer cylinder which is a member having a bottomed cylindrical shape and an opening side end of which is fitted onto the inner cylinder so as to cover at least a portion of the exhaust purification member,
Inside the casing,
a first space which is a gap between an outer peripheral surface of the inner cylinder and an inner peripheral surface of the outer cylinder;
A second space between an end of the inner cylinder and a bottom of the outer cylinder;
is formed,
the casing and the exhaust manifold are connected such that an internal space of a collecting pipe of the exhaust manifold and the first space communicate with each other through an inlet which is an opening formed in a side surface of the outer cylinder,
In a first projection view, which is a vertical projection view of the flow direction of exhaust gas flowing from the internal space of the collecting pipe to the first space through the inlet, the entire inlet overlaps with the inner cylinder.
An exhaust system for an internal combustion engine, comprising:
