Patent abstract
A method of operating a boosted engine system is described in which an ejector coupled with a fuel vapor purging system can generate vacuum during both purging and non-purging conditions, and during both boosted and non-boosted conditions. The vacuum can therefore be used to power vacuum actuated brakes, and/or other vacuum actuators, irrespective of the purging conditions, and irrespective of boost levels.
