Abstract
Vehicle engine systems and inserts for such systems are presented. The insert can be positioned between an air intake system and a cylinder bank of an engine. In some arrangements, the insert can be positioned such that a first abutment surface directly contacts portions of a surge tank and a second abutment surface directly contacts portions of a cylinder head cover. The insert can be constructed, positioned, and/or oriented to absorb or transfer forces acting upon the engine system during impacts. For instance, the insert can be arranged such that it extends between the surge tank and the cylinder head cover along an axis that is substantially parallel to a predetermined force direction of a predetermined impact force.
Claims17
A vehicle engine system, comprising:
- a cylinder bank including a cylinder head and a cylinder head cover;
- an air intake system including a lower intake manifold and a surge tank, the lower intake manifold being operatively connected to the cylinder head, and the surge tank being operatively connected to the lower intake manifold;
- and
- an insert positioned between the cylinder bank and the air intake system such that the insert directly contacts at least a portion of the air intake system and at least a portion of the cylinder bank, the insert filling a majority of the space between the cylinder head cover and the surge tank in an area in which the insert is positioned.
A vehicle engine system, comprising:
- a cylinder bank including a cylinder head and a cylinder head cover;
- an air intake system including a lower intake manifold and a surge tank, the lower intake manifold being operatively connected to the cylinder head, and the surge tank being operatively connected to the lower intake manifold;
- and
- an insert positioned between the cylinder bank and the air intake system such that the insert directly contacts at least a portion of the air intake system and at least a portion of the cylinder bank,
- wherein the insert extends between the surge tank and the cylinder head cover along an axis substantially parallel to a predetermined impact force direction during a predetermined impact condition.
A vehicle engine system, comprising:
- a cylinder bank including a cylinder head and a cylinder head cover;
- an air intake system including a lower intake manifold and a surge tank, the lower intake manifold being operatively connected to the cylinder head, and the surge tank being operatively connected to the lower intake manifold;
- an engine component extending between the cylinder bank and the air intake system;
- and
- an insert operatively connected to the cylinder bank and the air intake system via an interference fit, the insert extending above the engine component and directly contacting the surge tank and the cylinder head cover,
- the insert having a lower engine-facing surface, the lower engine-facing surface including a first abutment surface shaped to directly engage a contour of the surge tank and a second abutment surface shaped to directly engage a contour of the cylinder head cover, the first abutment surface and the second abutment surface being a majority of the lower engine-facing surface.
A vehicle engine system, comprising:
- a cylinder bank including a cylinder head and a cylinder head cover;
- an air intake system including a lower intake manifold and a surge tank, the lower intake manifold being operatively connected to the cylinder head, and the surge tank being operatively connected to the lower intake manifold;
- an engine component extending between the cylinder bank and the air intake system;
- and
- an insert operatively connected to the cylinder bank and the air intake system via an interference fit, the insert extending above the engine component and directly contacting the surge tank and the cylinder head cover,
- wherein the insert extends between the surge tank and the cylinder head cover along an axis substantially parallel to a predetermined impact force direction during a predetermined impact condition.
A method for providing an insert within an engine system, the engine system including a surge tank and a cylinder head, the method comprising:
- predicting a translational and rotational movement of the engine system within a vehicle during a predetermined impact condition;
- and
- determining an impact force direction of a force applied to the surge tank during the predetermined impact condition;
- and
- positioning an insert between the surge tank and a cylinder head cover such that the insert directly contacts at least a portion of the surge tank and at least a portion of the cylinder head and such that the insert extends between the surge tank and the cylinder head cover along an axis substantially parallel to the impact force direction during the predetermined impact condition.
