Heat shield for internal combustion engine exhaust system

A heat shield for an exhaust system member extending from an exhaust port of an internal combustion engine, comprising:

• a first heat shield plate for surrounding substantially all of a curved section of the exhaust system member, the curved section of the exhaust system member extending from the exhaust port;
• a second heat shield plate mounted over 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,
• wherein the first heat shield plate is formed as a single plate extending along at least half way along the curved section of the exhaust system member,
• wherein a rear end section of the first heat shield plate is in direct contact with the exhaust member and a front end section of the second heat shield plate is separated from the exhaust system, thereby forming a gap between the rear end section of the first heat shield plate and the front end section of the second heat shield plate,
• wherein the gap provides an opening facing toward a front side of the vehicle so that travel wind from the front side of the vehicle passes though a gap between the first and second heat shield p1ates,
• wherein a small diameter section is provided on the rear end section of the first heat shield plate, and the front end section of the second heat shield plate overlaps the small diameter section along a length of the exhaust system member, with the gap in a radial direction being provided between the small diameter section of the rear end section of the first heat shield plate and the front end section of the second heat shield plate.

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,
• wherein the end section of the first heat shield plate away from the exhaust port is fixed tightly around the exhaust system member by the band member, and the end section of the second heat shield plate extends forwardly over the band member, the end section of the second heat shield member being fixed to the exhaust system member by an attachment fixture including a bolt, the attachment fixture separating the second heat shield member from the exhaust system member and providing a space between the second heat shield plate and the exhaust system member along an entire length of the second heat shield member through which air passes from front to back during travel.
