Abstract
Methods and systems are provided for generating vacuum via a throttle. In one example, a method may comprise rotating the throttle to a first fully closed position to provide vacuum to a first vacuum consumption device and rotating the throttle to a second fully closed position to provide vacuum to a second vacuum consumption device. The method may further include rotating the throttle to a partially closed position to provide vacuum to both the first and second vacuum consumption devices.
Claims14
A method comprising:
- rotating a flexible throttle at a first threshold amount of power to prevent the flexible throttle from bending when in contact with one or more of a plurality of protrusions of an intake passage;
- rotating the flexible throttle at a second threshold amount of power to allow the flexible throttle to bend when contacting the plurality of protrusions;
- generating vacuum at the flexible throttle for at least first and second vacuum consumption devices coupled to the flexible throttle via the rotating;
- fully closing the flexible throttle to a first fully closed position in response to vacuum of the first vacuum consumption device being less than a threshold vacuum;
- and
- fully closing the flexible throttle to a second, different, fully closed position in response to vacuum of the second vacuum consumption device being less than the threshold vacuum.
