Engine intake air flow control assembly

An intake manifold assembly comprising:

• an intake manifold defining first and second intake passages providing air flow to first and second intake ports of a cylinder head;
• a first vane rotatably coupled to the intake manifold and located within an outlet of the first intake passage, the first vane displaceable from an open position where the first vane extends along a first wall defining the first intake passage to a closed position where the first vane extends inwardly from the first wall to obstruct an air flow to the first intake port;
• a second vane rotatably coupled to the intake manifold and located within the second intake passage, the second vane displaceable from an open position where the second vane extends along a second wall defining the second intake passage to a closed position where the second vane extends inwardly from the second wall to obstruct an air flow to the second intake port;
• a first pivot member rotatably coupled to the intake manifold adjacent the first wall, the first vane fixed for rotation with the first pivot member;
• a second pivot member rotatably coupled to the intake manifold adjacent the second wall, the second vane fixed for rotation with the second pivot member;
• a first arm having a first end fixed for rotation with the first pivot member;
• a second arm having a first end fixed for rotation with the second pivot member;
• and
• a third arm coupled to a second end of the first arm and coupled to a second end of the second arm, the second end of the first arm and the second end of the second arm being fixed for displacement with the third arm.

An engine assembly comprising:

• a cylinder head defining first and second intake ports;
• an intake manifold assembly coupled to the cylinder head and defining a first intake passage in communication with the first intake port and a second intake passage in communication with the second intake port;
• a first vane rotatably coupled to the intake manifold assembly and located within an outlet of the first intake passage, the first vane displaceable from an open position where the first vane extends along a first wall defining the first intake passage to a closed position where the first vane extends inwardly from the first wall to obstruct an air flow to the first intake port;
• a second vane rotatably coupled to the intake manifold assembly and located within the second intake passage, the second vane displaceable from an open position where the second vane extends along a second wall defining the second intake passage to a closed position where the second vane extends inwardly from the second wall to obstruct an air flow to the second intake port;
• an actuation mechanism coupled to the first and second vanes to rotate the first and second vanes between the opened and closed positions;
• a first pivot member rotatably coupled to the intake manifold assembly adjacent the first wall, the first vane fixed for rotation with the first pivot member;
• a second pivot member rotatably coupled to the intake manifold adjacent the second wall, the second vane fixed for rotation with the second pivot member;
• a first arm having a first end fixed for rotation with the first pivot member;
• a second arm having a first end fixed for rotation with the second pivot member;
• and
• a third arm coupled to the actuation mechanism and coupled to a second end of the first arm and a second end of the second arm, the second end of the first arm and the second end of the second arm being fixed for displacement with the third arm.
