    • An object is to provide an abnormal combustion determining apparatus for an internal combustion engine that can identify a major factor causing an oil to flow into a cylinder. The abnormal combustion determining apparatus for the internal combustion engine that includes a plurality of cylinders detects, for each cylinder, a cylinder in which abnormal combustion has occurred. The cylinder in which the abnormal combustion has occurred, and a history of load applied during an operation are stored in memory. It is determined whether or not the cylinder in which the abnormal combustion has occurred and which is stored in memory, is a specific cylinder. It is determined whether or not load present in the history stored in memory and used prior to the occurrence of the abnormal combustion is higher than a threshold value. Based on a combination of a decision made by the cylinder determining means and a decision made by the load determining means, a major factor causing the oil to flow into the cylinder is identified from among relations established for factors of oil flowing into the cylinder according to the combination of these decisions made.
    • 本发明的目的是提供一种用于内燃机的异常燃烧确定装置,其能够识别导致油流入气缸的主要因素。 包括多个气缸的用于内燃机的异常燃烧确定装置针对每个气缸检测发生异常燃烧的气缸。 发生异常燃烧的气缸和操作期间的负载历史被存储在存储器中。 确定发生了异常燃烧的气缸是否存储在存储器中是特定气缸。 确定存储在存储器中并且在发生异常燃烧之前使用的历史中的负载是否高于阈值。 基于由气缸确定装置作出的决定与负荷确定装置的决定的组合,从根据根据下列情况的油流入气缸的因素建立的关系中确定导致油流入气缸的主要因素 这些决定的结合。
