摘要： An engine exhaust apparatus includes an exhaust passage for flowing exhaust gas emitted from an engine, a flow rectifier for rectifying the flow of the exhaust gas, and an exhaust heat recovery unit disposed in the exhaust passage downstream of the flow rectifier. The exhaust heat recovery unit is provided with an exhaust heat recovery portion and a cooling portion to cool the exhaust heat recovery portion. The engine exhaust apparatus further includes a first diameter reducing portion gradually reduced in diameter toward the exhaust heat recovery unit from the flow rectifier, and a second diameter reducing portion gradually reduced in diameter toward the downstream from the exhaust heat recovery unit.

摘要： An exhaust device of an engine, with an exhaust path to lead exhaust gas discharged from the engine to outside, the exhaust device comprising: an exhaust heat collector being configured to collect heat from the exhaust gas, and a cooling part being configured to cool down the exhaust heat collecting part from an outer peripheral side via a cooling fluid; and an exhaust gas flow controlling member in a cylindrical shape, comprising an inlet part and an outlet part where the inflow of the exhaust gas is discharged to an upstream side of the exhaust heat collecting part. An opening diameter of the outlet part is arranged to be smaller than an outer diameter of the exhaust heat collecting part. The exhaust gas flow controlling member is placed so that an open end of the outlet part opposes a central portion of an upstream end plane of the exhaust heat collecting part. The open end of the outlet part and the upstream end plane of the exhaust heat collecting part are a predetermined distance apart.
