Abstract
Abstract There is provided a wire guide for guiding and protecting wires from moving parts underneath the valve cover in a diesel engine. The wire guide has a channel portion connected to a base for securing the wire guide to the cylinder head. The base may be comprised of a retaining clip having two prongs that form an assembly that “snaps-on” to an injector clamp holder to secure the wire guide to the cylinder head. The channel portion is configured to cross a rocker arm when the wire guide is mounted on the cylinder head. The channel portion creates a conduit for holding the wires. The conduit is partially closed on at least one side and has an open side with intermittently spaced retaining tabs. The retaining tabs may be intermittently spaced as a series of pair tabs or alternating opposing singular tabs.

Claim 8
Dependent Claim
38 words
The wire guide of claim 1 , wherein the retaining tabs comprise: a) a tapered face; b) an upper edge that forms an outer edge of the channel portion; and c) a lower edge that defines a conduit.
Claim 9
Dependent Claim
63 words
The wire guide of claim 7 , wherein the tab pair defines a) a first distance between the upper edges of the tab pair; and b) a second distance between the lower edges of the tab pair wherein the first distance is larger than the second distance; c) whereby the tab pair results in an inverted wedge-shaped opening between the retaining tab pair.
Claim 10
Dependent Claim
77 words
A wire guide for use in an engine, the wire guide comprising: a) a channel portion having an open side with intermittently spaced retaining tabs, wherein the channel portion comprises at least two members forming at least one bend; and b) a base connected to the channel portion; c) whereby the wire guide can be secured to a cylinder head such that wires are guided and protected from moving parts underneath a valve cover in an engine.
Claim 11
Dependent Claim
77 words
A wire guide for use in an engine, the wire guide comprising: a) a channel portion having an open side with intermittently spaced retaining tabs, wherein the channel portion comprises at least two members forming at least one bend; and b) a base connected to the channel portion; c) whereby the wire guide can be secured to a cylinder head such that wires are guided and protected from moving parts underneath a valve cover in an engine.
