ABSTRACT:
Internal combustion engine control and diagnostics provides for delivery of a fuel quantity and intake air to engine cylinders and for an ignition signal to ignite the air and fuel, wherein misfire conditions in the cylinder are diagnosed over all operating conditions through a reference period model of the components of measured reference periods not attributed to a misfire condition and through removal of such components from measured reference periods yielding a resultant reference period component sensitive only to misfire conditions. The magnitude, position, and stability of the resultant component indicates misfire severity, location, and persistence.
