METHOD AND SYSTEM FOR ENGINE SPEED CONTROL |
| 摘要 |
Methods and systems are provided for engine speed flare control in an engine system having multiple staged charge boosting devices. In one example, during an engine start, an upstream compressor is rotated backwards via an electric motor to reduce the intake manifold pressure. The engine is then fueled based on the lower manifold pressure to reduce torque and engine speed flare until idle engine speed conditions are reached. |
