Abstract
Methods and systems are provided for pressure control in a boosted engine system. A variable geometry turbine (VGT) geometry, and/or wastegate (WG), and/or an exhaust gas recirculation (EGR) valve opening is adjusted at least based on a difference between the exhaust pressure and an intake pressure in order to reduce the difference between exhaust and intake manifold pressures, thereby reducing pumping work losses.
