Method for improving cylinder-selective measuring of lambda values in exhaust gas of internal combustion engine with lambda probe, involves selectively increasing flow velocity of exhaust gas in exhaust gas line

摘要

The method involves selectively increasing the flow velocity of the exhaust gas in the exhaust gas line (6), which increases the pressure difference that is obtained by an opened outlet (4). The pressure difference is obtained between the outlet of a selected cylinder (2) and the exhaust gas line in comparison to the pressure difference between the outlet of another non-selected cylinder and the exhaust gas line.
