  • Engine throttle control with brake booster
    Patent number: 8726872
    Abstract: Methods and systems are provided for reducing variability in air-fuel control due to variations in brake booster vacuum levels at an engine start. A throttle position is adjusted during an engine start based on the vacuum availability in the brake booster to control a rate of intake aircharge flow. By allowing aircharge to enter the intake manifold at a more consistent rate, air-fuel control is improved and exhaust emissions are reduced.
    Type: Grant
    Filed: January 15, 2013
    Date of Patent: May 20, 2014
    Assignee: Ford Global Technologies, LLC
    Inventors: Stephen Michael White, Mike Liebert, Andrew Clement Dame, Ross Dykstra Pursifull
