Abstract
Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.
Claims6
A dual scroll turbocharger system, comprising:
- an exhaust flow passage with an interior dividing wall, the interior dividing wall partitioning the exhaust flow passage into a first scroll and a second scroll;
- and
- a branch communication valve positioned within the exhaust flow passage, the branch communication valve comprising a first chamber and a second chamber separated by a valve dividing wall, and rotatable around a rotational axis.
A dual scroll turbocharger system, comprising:
- a first scroll and a second scroll, fluidically separated by a dividing wall;
- a passage positioned adjacent to the dividing wall and bridging the first scroll and the second scroll;
- and
- a branch communication valve comprising a first chamber and a second chamber separated by a valve dividing wall and rotatable around a rotational axis, positioned within the passage and movable between an open position and a closed position, the open position increasing fluid communication between the first scroll and the second scroll.
