Abstract
A retention member is configured to be supported within a cylinder head of an engine and includes a body portion and a plurality of arms. The body portion has an opening configured to receive a fuel injector of the engine. Additionally, the plurality of arms extends from the body portion and is configured to be positioned over a portion of a cross-head of the engine. The plurality of arms is spaced apart from the cross-head during routine operation of the engine.
Claims19
A retention member configured to be supported within a cylinder head of an engine, comprising:
- a body portion having an opening configured to receive a fuel injector of the engine;
- and
- a plurality of arms extending from the body portion and configured to be positioned over a portion of a cross-head of the engine, the plurality of arms being spaced apart from the cross-head during routine operation of the engine.
A retention member configured to be operably coupled to a valvetrain assembly of an engine, comprising:
- a body portion positioned intermediate a first valve and a second valve of the valvetrain assembly;
- a first plurality of arms configured to be positioned relative to the first valve;
- and
- a second plurality of arms configured to be positioned relative to the second valve, and the body portion, first plurality of arms, and second plurality of arms are stationary relative to movement of the first and second valves, wherein each of the first and second plurality of arms defines a recess configured to receive a portion of a cross-head of the valvetrain assembly.
A retention member configured to be operably coupled to a valvetrain assembly of an engine, comprising:
- a body portion positioned intermediate a first valve and a second valve of the valvetrain assembly;
- a first plurality of arms configured to be positioned relative to the first valve;
- and
- a second plurality of arms configured to be positioned relative to the second valve, and the body portion, first plurality of arms, and second plurality of arms are stationary relative to movement of the first and second valves, wherein the body portion is configured to be removably coupled with a fuel injector of the engine.
An engine, comprising:
- a cylinder having a body portion and a cylinder head portion configured to be coupled with the body portion;
- a valvetrain assembly supported on at least a portion of the cylinder and including an intake valve, an exhaust valve, a first cross-head operably coupled to the intake valve, and a second cross-head operably coupled to the exhaust valve;
- and
- a retention member configured to maintain a position of the first and second cross-heads relative to the intake and exhaust valves, and the retention member is removable relative to the cross-heads.
