Monitoring delivery of secondary air into internal combustion engine exhaust gas involves using output signals of lambda probes in exhaust gas channels to determine uneven distribution of air mass

摘要

The method involves using the output signals of lambda probes (19,20) in at least two exhaust gas channels (12,13) of the internal combustion engine (10) with catalysers (17,18) to determine the actual quantity of air fed into the individual exhaust channels and in order to
