Abstract
A system for limiting the ingress of oil into an induction feed pipe provided in the cylinder head cover of an internal combustion engine is disclosed. The system provides a cylinder head cover including a cylinder head cover outlet, a top plate spaced from the cylinder head cover outlet, and a perforated deflector plate. The top plate and deflector plate define a chamber in communication with the cylinder head cover outlet.
Claims29
A deflector comprising:
- a cylinder head cover outlet;
- a baffle plate at least partially defining a fluid passage;
- and
- a perforated deflector plate disposed between the cylinder head cover outlet and fluid passage, each perforation of the deflector plate having an axis that extends completely through the plate from an upstream side to a downstream side of the deflector plate at an angle that is substantially perpendicular to the plate,
- the deflector plate including an aperture for receiving the cylinder head cover outlet.
An internal combustion engine comprising:
- a deflector including
- a cylinder head cover outlet;
- a baffle plate at least partially defining a fluid passage;
- and
- a perforated deflector plate disposed between the cylinder head cover outlet and fluid passage, each perforation of the deflector plate having an axis that extends completely through the plate from an upstream side to a downstream side of the deflector plate at an angle that is substantially perpendicular to the plate,
- the deflector plate including an aperture for receiving the cylinder head cover outlet.
A method of limiting the ingress of liquid oil into a cylinder head cover outlet of an internal combustion engine, the method comprising the steps of:
- providing a top plate spaced from the cylinder head cover outlet;
- providing a perforated deflector plate such that the top plate and deflector plate define a chamber in communication with the cylinder head cover outlet, each perforation of the deflector plate having an axis that extends completely through the plate from an upstream side to a downstream side of the deflector plate at an angle that is substantially perpendicular to the plate;
- and
- receiving the cylinder head cover outlet in an aperture in the deflector plate.
