Claims15
A system comprising:
- an intake valve for an internal combustion engine, the intake valve having a valve stem with a hole in the valve stem forming an air channel there through that allows intake air to flow from an intake passage, through the air channel, into a cylinder of the internal combustion engine, wherein
- an axis of the air channel through the valve stem is parallel with an axis of the intake passage.
An internal combustion engine system comprising:
- a piston positioned within a bore of a cylinder;
- an intake valve that selectively seals an air intake passage to allow and block a flow of intake air from the intake passage into the cylinder, the intake valve having a valve stem with a hole in the valve stem forming an air channel there through that allows intake air to flow from the intake passage, through the air channel, into the cylinder, wherein
- an axis of the air channel through the valve stem is parallel with an axis of the intake passage.
A method comprising:
- directing air, with an intake valve of an internal combustion engine, from an intake passage towards a lip of a valve head of the intake valve using a hole in a valve stem of the intake valve that forms an air channel through the valve stem of the intake valve, wherein
- an axis of the air channel through the valve stem is parallel with an axis of the intake passage.
