摘要： Methods and systems are provided for mitigating engine pre-ignition based on a feed-forward likelihood of pre-ignition and feedback from a pre-ignition event. In response to an indication of pre-ignition, a cylinder may be enriched while an engine load is limited. The enrichment may be followed by an enleanment to restore exhaust catalyst feed-gas oxygen levels. The mitigating steps may be adjusted based on engine operating conditions, a pre-ignition count, as well as the nature of the pre-ignition.
摘要翻译： 提供的方法和系统是基于预先点火的前馈可能性和来自预先点火事件的反馈来缓解发动机预点火。 响应于预先点火的指示，当发动机负载受到限制时，气缸可以被富集。 浓缩之后可以进行净化，以恢复废气催化剂的进料气氧含量。 减轻步骤可以根据发动机的运行条件，预先点火计数以及预燃的性质进行调整。

摘要： Methods and systems are provided for identifying and differentiating knock and pre-ignition using a plurality of knock sensors distributed along an engine block. By dynamically adjusting cylinder-specific assignment of the knock sensors for knock detection and pre-ignition detection based on operating conditions of each cylinder, knock and pre-ignition is more reliably identified and distinguished.
