<p>An adjusting system (14) for adjusting the quantity of fuel delivered to an internal combustion engine has a first adjusting unit (10.1.1) and a second control unit (10.2.1). The first control unit gives a first adjusting value to the fuel injection pump (12.1) on the basis of signals fed to it from a first sensor arrangement (11.1). The second adjusting unit determines a second adjusting value on the basis of signals from a second sensor arrangement (11.2), which would also be directly suitable for controlling the fuel injection pump but which is used to calibrate the first adjusting unit. The adjusting system of this design is then applied when the second sensor arrangement used measures more slowly but more accurately than the first sensor arrangement. In this case, the second adjusting value is better suited to achieving a value required for the desired lambda value than the first adjusting value. The first adjusting value reacts more quickly to changes in the quantity of air fed to the internal combustion engine. In order to calibrate the first control unit using the second adjusting value, the first adjusting value is controlled more accurately than was previously possible but still as rapidly.</p> |
