Monitoring program for the cylinder is not equal to the weight of the downstream of the catalytic converter

摘要

Disclosed are methods and systems for detecting a cylinder - - - imbalance air fuel provided. In one example, a process which is the adjustment of the force of machines operation on the basis of an indication of a cylinder - - - imbalance air fuel contain. The imbalance, on the basis of an output of a second exhaust gas sensor and a plurality of cylinder-individual weighting factors are detected, wherein the second sensor in an exhaust system in the exhaust system on the outlet side of a first sensor is located.
