Embodiments for generating vacuum at a throttle are presented. In one example, a system comprises a throttle positioned in an intake of an engine, and a peripheral venturi proximate the throttle, the venturi having an inlet positioned to interface with an edge of the throttle when the throttle is in a partially open position. In this way, vacuum may be generated by flow air through the venturi.
