Method for adapting the signal (») measured by a lambda probe (25) for detecting the concentration of oxygen operating in an exhaust line (24) of an internal combustion engine (10) of a vehicle, of the type comprising acquiring (35, 33) in processing mean...

The system has an engine operating conditions monitoring unit (16) including a detection unit (24) that detects stopping of fuel injection in cylinders of a diesel engine (8), to activate operation of an effective signal acquiring unit (18) and a drift coe...

The method involves measuring the residual oxygen in the exhaust gas with a linear broad band lambda probe and passing a corresponding signal to a controller that generates a signal for influencing the air-fuel ratio into the engine. The actual lambda prob...
