Abstract
A boot includes an annular body that defines a thru-bore with a thru-bore diameter, and a bore axis. The boot further defines an overall axial length, an exterior, a first axial end, a second axial end, and an aperture that radially extends from the thru-bore to the exterior.
Claims16
A fuel injector, a cylinder head, and a fuel supply interface comprising:
- a fuel injector having an at least partially annular body defining a longitudinal axis, and a radial direction, and including
- a fuel inlet;
- an injection outlet;
- an electrical connector;
- a doubled walled conduit attached to the fuel injector;
- and
- a boot disposed about the at least partially annular body of the fuel injector and the doubled walled conduit, the boot including
- an annular body defining
- a thru-bore with a bore diameter, and a bore axis;
- an overall axial length;
- an exterior;
- a first axial end, and a second axial end;
- and
- an aperture extending radially from the thru-bore to the exterior.
