Heat shield for engine mount

1. A heat shield adapted to protect an engine mount, said engine mount being positionable between an engine and a support frame, said heat shield comprising:

a substrate positionable substantially surrounding said engine mount, said substrate having a heat reflecting surface facing outwardly away from said engine mount to block radiant heat transfer; and

a flexible attachment member attached to said substrate, said attachment member being formed of a heat insulating material and being positionable relatively to said engine mount for fixing said substrate in said position surrounding said engine mount, said attachment member reducing conductive heat transfer to said engine mount.

2. A heat shield according to claim 1 , wherein said substrate comprises a woven glass fiber mat and said reflective surface comprises a metal foil attached to said mat.

3. A heat shield according to claim 1 , wherein said attachment member comprises a tab formed of a fiber reinforced polymeric matrix.

4. A heat shield according to claim 3 , wherein said attachment member comprises a hinge element between said tab and said substrate for hingedly attaching said attachment member thereto.

5. A heat shield according to claim 4 , wherein said hinge element comprises a portion of said substrate.

6. A heat shield adapted to protect an engine mount, said engine mount being positionable between an engine and a support frame, a plurality of studs projecting from opposite ends of said engine mount and engaging said engine and said support frame, said heat shield comprising:

a substrate positionable substantially surrounding said engine mount, said substrate having a heat reflecting surface facing outwardly away from said engine mount; and

a flexible attachment member attached to said substrate, said attachment member having an aperture therethrough adapted to receive one of said studs for attaching said substrate in said position surrounding said engine mount, said attachment member being positionable relatively to said engine mount for fixing said substrate in said position surrounding said engine mount.

7. A heat shield according to claim 6 , further comprising a second attachment member attached to said substrate and being positioned in spaced apart relation to said first named attachment member, said second attachment member having an aperture therethrough for receiving one of said studs.

8. A heat shield according to claim 7 , wherein said first and second attachment members are positioned along a common edge of said substrate.

9. A heat shield according to claim 7 , wherein said first and second attachment members are both positionable between said engine and said engine mount.

10. A heat shield according to claim 9 , wherein said first and second attachment members are comprised of a heat insulating material.

11. A heat shield according to claim 9 , wherein said first and second attachment members are both positionable between said frame and said engine mount.

12. A heat shield adapted to protect an engine mount, said engine mount being positionable between an engine and a support frame, said heat shield comprising:

a substrate positionable substantially surrounding said engine mount, said substrate having a heat reflecting surface facing outwardly away from said engine mount to block radiant heat transfer, said substrate having a curved shape; and

an attachment member attached to said substrate at at least a first and a second position in spaced apart relation along said substrate, said attachment member being positionable relatively to said engine mount for fixing said substrate in said position surrounding said engine mount, said attachment member holding said substrate in said curved shape.

13. A heat shield according to claim 12 , wherein said substrate comprises a woven glass fiber mat and said reflective surface comprises a metal foil attached to said mat.

14. A heat shield according to claim 12 , wherein said attachment member is formed of a heat insulating material reducing conductive heat transfer to said engine mount.

15. A heat shield according to claim 12 , wherein said attachment member comprises a fiber reinforced polymeric matrix.

16. A heat shield according to claim 12 , further comprising first and second hinge elements positioned between said attachment member and said substrate at said first and said second positions respectively for attaching said attachment member thereto.

17. A heat shield according to claim 16 , wherein said first and second hinge elements comprise respective first and second portions of said substrate.

18. A method of protecting an engine mount from heat of an engine, said method comprising:

providing a heat shield comprising a flexible substrate having a heat reflecting surface thereon, said heat shield having first and second attachment members, said attachment members being attached to said substrate in spaced apart relation;

forming said substrate so as to surround said engine mount, said heat reflecting surface facing outwardly from said engine mount; and

attaching said first and second attachment members to said engine mount.

19. A method according to claim 18 , further comprising forming said substrate into a curved shape.

20. A method according to claim 18 , further comprising attaching said first and second attachment members to said engine mount between said engine and said engine mount.
