Abstract
A vacuum system is provided. The vacuum system includes a vacuum aspirator coupled to a housing of an intake manifold, the vacuum aspirator including an air intake port, a vacuum port, and a manifold port. The vacuum system also includes a manifold vacuum passage and a vacuum reservoir passage traversing the housing of the intake manifold, the manifold vacuum passage coupled to the manifold port and the vacuum reservoir passage coupled to the vacuum port.
Claims20
A vacuum system comprising:
- a vacuum aspirator directly coupled to a housing of an intake manifold, where the vacuum aspirator includes an air intake port, a vacuum port, a manifold port, and a housing, where the housing includes a surface surrounding the manifold port and is in face-sharing contact with a section of the housing of the intake manifold adjacent to a manifold vacuum passage traversing through a wall of the housing of the intake manifold;
- and
- a vacuum reservoir passage traversing the wall of the housing of the intake manifold;
- where the wall defines a boundary of an interior section of the intake manifold;
- where the manifold vacuum passage is coupled to the manifold port and the vacuum reservoir passage is coupled to the vacuum port;
- and
- where the manifold vacuum passage includes an inlet positioned in the wall of the intake manifold housing and directly opens into the manifold port.

A method for operating a vacuum system, comprising:
- during a first operating condition, increasing a vacuum pressure in a vacuum reservoir by drawing air from the vacuum reservoir to a vacuum aspirator through a vacuum conduit extending through a housing of an intake manifold, the vacuum conduit coupled to a vacuum port in the vacuum reservoir, where the vacuum aspirator includes a housing, where the housing includes a surface surrounding the manifold port and is in face-sharing contact with a section of the housing of the intake manifold adjacent to a manifold vacuum passage traversing through a wall of the housing of the intake manifold;
- and
- during a second operating condition, providing a vacuum to an engine system from the vacuum reservoir;
- where the vacuum conduit includes an inlet positioned in the wall of the intake manifold housing and directly opens into the vacuum port.
