ABSTRACT:
A work machine having dual compression ignition engines each driving motor generators providing a power output to selective loads. The compression ignition engines each have an exhaust aftertreatment device requiring regeneration in accordance with a selected parameters. A controller controls motor/generators or hydraulic pump/motors associated with the diesel engines to either transfer load between one or the other of the motor/generators or pump/motors to impose a load on one of the engines sufficiently high to produce passive regeneration. In the event that loads driven by the motor/generators or pump/motors are too low, one of the engines may be shut off or the loads increased.
