Abstract
An intake manifold is disclosed. The intake manifold includes a first chamber in fluid communication with a PCV line and disposed generally upstream of a second chamber. The chambers are designed to provide a long flow path for the moisture laden PCV gas and to help reduce the introduction of moisture or fluids into the second chamber. This helps to prevent the ingestion of moisture or fluids by the combustion chambers of engine. An optional fluid blocker can also be used to trap fluids and help prevent those fluids from entering a cylinder port.
Claims19
An intake manifold comprising:
- a first chamber in fluid communication with a PCV line and disposed generally upstream of a second chamber,
- the first chamber having a first moisture content and the second chamber having a second moisture content,
- wherein the first moisture content is greater than the second moisture content;
- wherein the first chamber is separated from the second chamber by a generally horizontal wall;
- and
- wherein the horizontal wall is formed by a gasket.
An intake manifold comprising:
- a first chamber in fluid communication with a PGV line and disposed generally upstream of a second chamber,
- the first chamber having a first moisture content and the second chamber having a second moisture content,
- wherein the first moisture content is greater than the second moisture content;
- and
- wherein the first chamber is formed by a groove formed in an upper cover associated with the intake manifold.
An intake manifold comprising:
- a first chamber in fluid communication with a PCV line and disposed generally upstream of a second chamber,
- the first chamber having a first moisture content and the second chamber having a second moisture content,
- wherein the first moisture content is greater than the second moisture content;
- and
- wherein the second chamber is formed by a groove disposed in the intake manifold.
An intake manifold comprising:
- a first chamber in fluid communication with a PCV line and disposed generally upstream of a second chamber,
- the first chamber having a first moisture content and the second chamber having a second moisture content,
- wherein the first moisture content is greater than the second moisture content;
- and
- wherein a gasket is disposed between a groove formed in the upper cover and a groove formed in the intake manifold, the groove in the upper cover forming the first chamber and the groove in the intake manifold forming the second chamber, wherein the gasket divides the first chamber from the second chamber.
