Title:
EXHAUST STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/182495
Kind Code:
A1
Abstract:
Provided is an exhaust structure that makes it possible to suppress corrosion. In this exhaust structure, an upstream-side exhaust pipe and a downstream-side exhaust pipe through which exhaust gas emitted from an internal combustion engine flows are connected in series. The inner diameter of the downstream end of the upstream-side exhaust pipe is smaller than the inner diameter of the upstream end of the downstream-side exhaust pipe. The downstream end of the upstream-side exhaust pipe is inserted into the upstream end of the downstream-side exhaust pipe, and is fixed with the outer peripheral surface of the downstream end of the upstream-side exhaust pipe in mutual contact with the inner peripheral surface of the upstream end of the downstream-side exhaust pipe.
