Abstract
Official abstract text for this publication.
Methods and systems are provided for reducing turbo lag in a boosted engine. A boost reservoir coupled to the engine may be charged with compressed intake air and/or combusted exhaust gas. The pressurized charge may then be discharged during a tip-in to either the intake or the exhaust manifold.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling a turbocharged engine with an electronic controller, comprising: responsive to a first accelerator pedal tip-in determined by the controller, discharging pressurized charge from a boost reservoir to an intake manifold via an intake discharge valve; and during a second accelerator pedal tip-in determined by the controller, discharging pressurized charge from the boost reservoir to an exhaust manifold via an exhaust discharge v…
