METHOD AND SYSTEM FOR PRE-IGNITION CONTROL |
| 摘要 |
Methods and systems are provided for addressing pre-ignition by mechanically varying a piston displacement within a combustion chamber. In response to pre-ignition, a static compression ratio may be reduced until a threshold lower compression ratio is reached. Further pre-ignition is then addressed with enrichment, thereby reducing the amount of pre-ignition mitigating enrichment required overall. |
