The present disclosure provides methods and systems for improved fouling spark plug detection. Methods and systems for determining the presence or absence of engine misfire or spark plug fouling are presented. In one example, an engine speed change rate is arranged in an engine data block, and a root mean square value of the engine speed change rate is determined. The presence or absence of engine misfire or spark plug fouling may be based at least in part on the root mean square value.
本公开提供了“用于改进积垢火花塞检测的方法和系统”。呈现了确定发动机失火或火花塞积垢的存在或不存在的方法和系统。在一个示例中,发动机转速变化率布置在发动机数据块中,并且确定所述发动机转速变化率的均方根值。发动机失火或火花塞积垢的所述存在或不存在可至少部分地基于所述均方根值。
