Heat shield for internal combustion engine exhaust system
First Claim
1. A heat shield for a vehicle having an exhaust system member extending from an exhaust port of an internal combustion engine, the heat shield comprising:
- a first heat shield plate for surrounding a curved section of the exhaust system member, the curved section being provided in the vicinity of the exhaust port;
a second heat shield plate for covering above a straight section of the exhaust system member, the straight section connecting to the curved section; and
a band member for supporting the first heat shield plate on the exhaust system member.

Abstract
A heat shield for an internal combustion engine exhaust system for supporting a first heat shield plate and a second heat shield plate on a U-shaped exhaust pipe extending from an exhaust port of an engine, via a support member such as band members, and heat shield plate attachment fixtures. The first heat shield plate covers all around a curved section of the U-shaped exhaust pipe in the vicinity of the exhaust port. The second heat shield plate covers an upper part of a straight section of the U-shaped exhaust pipe and extends rearwardly from the curved section. Further, since the exhaust pipe is formed as one piece, the first heat shield plate may be formed as a simple two-part structure using the band members. With this configuration, an effective heat shielding effect can be exhibited, and cost can be reduced.
