METHODS AND SYSTEMS FOR PROVIDING TRANSIENT TORQUE RESPONSE |
| 摘要 |
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. |

1. A method for an engine, comprising:
during a transient condition, when a desired inlet manifold pressure is greater than a throttle inlet pressure of a first throttle, if a pressure drop across a second throttle that is positioned upstream from the first throttle in an intake passage is greater than a pressure threshold, opening the second throttle to increase the throttle inlet pressure. |
