Lambda regulation Catalytic converter can correctly work only if the coefficient of excess of air l is perhaps closer to 1 that corresponds to a ratio of fuel/air 14,7:1. In order that it was carried out in practice, systems of injection MPI/MPFI are supplied so-called a lambda regulation. At the same time the lambda probe measures amount of oxygen in exhaust gases – comparable size for composition of mix of fuel/air. If the indicator deviates from ideal, the control unit regulates composition of mix. |
