An engine misfire detection system (10) for detecting engine misfire. System (10) includes a conventional controller (12) having a memory unit (14) and a plurality of sensors (16). Controller (12) includes a plurality of neural networks, which are trained by system (10), and which determine whether a firing event is a misfire based upon events occurring before the firing event and events occurring after the firing event. The neural networks are adaptively trained to compensate for the effects of engine variability and aging.

A system for determining whether a first firing event within an engine is a normal event or a misfire, said apparatus comprising:at least one sensor which measures first engine operating data which is associated with said first firing event, and second engine operating

[ What is claimed is:] [1.]1. A system for determining whether a first firing event within an engine is a normal event or a misfire, said apparatus comprising:at least one sensor which measures first engine operating data which is associated with said first firing event, and second engine operating data which is associated with at least one second firing event which occurs before said first firing event; anda controller which is communicatively coupled to said at least one sensor and which receives said first and second engine operating data, said controller including a plurality of neural networks which are employed by said controller to determine whether said first firing event is a misfire or a normal event based upon said first engine operating data and said second engine operating data.
