Prognostic engine system and method

The invention discloses an electronic controller for an engine programmed to operate in a prognostic mode, in which a baseline record of combustion parameters is created and stored in non-volatile memory, and in a diagnostic mode, in which an operating set of combustion parameters is compiled. During operation, the electronic controller retrieves the baseline record and compares it with the operating set to determine, in real time during engine operation, whether an abnormal combustion is present in the cylinder. The electronic controller activates at least one failure flag when the abnormal combustion is determined to be present. 本发明公开一种预测发动机系统和方法。用于发动机的电子控制器被编程用于：以预测模式运行，其中生成燃烧参数基准记录并存储在非易失性存储器中；并且以诊断模式运行，其中编译燃烧参数运行集合。在运行期间，电子控制器检索基准记录并且将其与运行集合比较以在发动机运行期间实时确定气缸中是否存在不正常燃烧。当确定存在不正常燃烧时电子控制器激活至少一个故障标记。
