Abstract
A method and system for providing a suitable engine torque response during a transient condition is presented. In one example, when a desired inlet manifold pressure is greater than a throttle inlet pressure of a first throttle, a second throttle positioned upstream from the first throttle is opened to increase the throttle inlet pressure. The method may provide an appropriate torque response while minimizing impact on fuel economy.
