Abstract
A method for controlling torque in an internal combustion engine to cause an increase in temperature in an exhaust aftertreatment device is disclosed. One group cylinders feed exhaust gases to one exhaust aftertreatment device and another group of cylinders feed exhaust gases to another exhaust aftertreatment device. By operating the groups of cylinders at different operating conditions, the desired temperature in one of the exhaust aftertreatment devices can be achieved while also providing driver demanded torque.
