Abstract
The invention is directed to a method and an arrangement for equalizing at least two cylinder banks of an internal combustion engine wherein a control parameter is corrected. The control parameter influences the torque contributions of the cylinder banks when a deviation in the quantities is determined. These quantities represent the torque contributions of the cylinder banks.
Claims7
A method for equalizing at least two cylinder banks of an internal combustion engine, the method comprising the steps of:
- controlling each of the cylinder banks with at least one control variable;
- determining a quantity representing the torque contributions of said cylinder banks;
- and
- correcting said at least one control variable in dependence upon said quantity in a sense of an equalization of said torque contributions of said cylinder banks.

An arrangement for equalizing at least two cylinder banks of an internal combustion engine, the arrangement comprising:
- a control apparatus for controlling the at least two cylinder banks by outputting at least one control variable;
- and
- said control apparatus including means for determining quantities representing the torque contributions of said cylinder banks;
- and means for correcting said at least one control variable in dependence upon said quantities in a sense of an equalization of said torque contributions of said cylinder banks.
