Abstract
Official abstract text for this publication.
Methods and systems are provided for introducing a charge motion to a cylinder via a bladder in an intake manifold runner. In one example, a system may include positioning a bladder in an intake port proximate to a cylinder.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising; adjusting, via compressed air from a compressed air source, each of a first variable bladder in a cylinder intake port and a second variable bladder in an intake manifold in response to a sensed vehicle operating parameter, the first variable bladder coupled in a cartridge that is inserted and positioned into an engine bulkhead between a cylinder and the cylinder intake port, the cartridge surrounded by coolant. 2. The method of claim 1 , wherein the adjusting includes at least three modes, including: a first mode including inflating the first variable bladder via the compressed air from the compressed air source without inflating the second variable bladder; a second mode including inflating the second variable bladder via the compressed air from the compressed air source without inflating the first variable bladder; and a third mode including inflating both the first and second variable bladders via the compressed air from the compressed air source. 3. The method of claim 2 , wherein the adjusting each of the first and second variable bladders is based on one or more of a throttle position and an engine load, and wherein the first, second, and third modes are mutually exclusive of one another.
