Abstract
Methods and systems are provided for regulating airflow through a charge air cooler integrated in an intake assembly. In one example, an engine intake assembly comprises a plenum having an integrated charge air cooler (CAC), a first header seal positioned around a circumference of a first CAC header, and a first rotatably movable seal positioned in a bypass passage of the plenum. The first movable seal interfaces via sliding contact with the first header seal and adjusting a position of the first movable seal may vary the amount of airflow through the bypass passage.
Claims13
An engine intake assembly comprising:
- a plenum having an integrated charge air cooler (CAC);
- a first header seal positioned around a circumference of a first CAC header;
- and
- a first rotatably movable seal positioned in a bypass passage defined between sides of a CAC body and the plenum and interfacing via sliding contact with the first header seal, the first rotatably movable seal varying airflow through the bypass passage.
An intake assembly in an engine, comprising:
- a compressor;
- a plenum positioned downstream from the compressor, the plenum having an integrated charge air cooler (CAC);
- a throttle body coupled to a downstream end of the plenum and including a plurality of intake runners coupled to cylinders of the engine;
- a first set of seals positioned around a circumference of header ends of the CAC;
- and
- a second set of seals positioned between exterior sides of a body of the CAC and the plenum and interfacing via sliding contact with the first set of seals, the second set of seals extending between a first header end of the CAC and a second header end of the CAC, where the second set of seals is adjustable between a first position where charge air flowing through the plenum bypasses the CAC and a second position where charge air flowing through the plenum flows through the CAC.
