Recognition process misfires worsening exhaust gas and damage the catalyst in combustion engines.

摘要

Recognition process misfires worsening exhaust gas and damage the catalyst in internal combustion engines with lambda disposed probe behind the catalyst, wherein misfires are recognized by analyzing the number of engine revolutions or by attracting other instability of engine operation in at least one cylinder of the internal combustion engine, wherein the voltage of the lambda probe is grasped with reference to the failure recognized combustion because, depending on the voltage the probe, the nature of the misfire is inferred.
