Abstract
Official abstract text for this publication.
Methods and systems are provided for providing vacuum to a brake booster via an aspirator system. In one example, a system may include an aspirator system fluidly coupled with a brake booster with no intervening components located therebetween.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: generating vacuum via motive flow in an aspirator system when a vehicle speed is greater than a threshold speed or when at least one cooling fan is activated; providing vacuum from the aspirator system to a brake booster in response to a check valve being open; and mixing suck flow from the brake booster with motive flow in the aspirator system and flowing the mixture directly out a rear grill without flowing the mixture through any other components. 2. The method of claim 1 , wherein activating the cooling fan is in response to the vehicle speed being less than the threshold speed or a coolant temperature being greater than a threshold temperature. 3. The method of claim 2 , wherein activating the cooling fan in response to a combination of the vehicle speed being less than the threshold speed and the coolant temperature being less than the threshold temperature further includes one or more or retarding spark, disabling coolant flow, and advancing spark timing. 4. The method of claim 1 , wherein generating vacuum includes flowing motive flow through a venturi passage, a spiral shaped passage, and an annular passage of the aspirator system.
