ABSTRACT:
An internal combustion engine misfire detection system is described which counts the transitions in the output of an oxygen sensor in a closed loop air/fuel ratio controller over a predetermined time period and compares the transition count with a limit count determined to be the number which would occur at the engine speed during a misfire condition. When the number of transitions exceeds the limit count, a warning lamp is energized and secondary air to an oxidizing converter is diverted to the atmosphere.
