An engine system includes a plurality of cylinders including one or more donating cylinders and one or more non-donating cylinders. A control module controls an operation of the one or more donating cylinders relative to, or based on, the operation of the one or more non-donating cylinders.

Engine system and method

A controller, in electrical communication with the one or more of the injectors and a high-pressure fuel pump, generates a first signal responsive to which the valve in the injector opens or closes and a second signal responsive to which the high-pressure fuel pump increases or decreases the pressure level in the fuel accumulator. The system may also include one or more sensors to detect a pressure within the air manifold and to detect the pressure within the fuel accumulator. The controller is programmed to calculate an in-cylinder gas pressure. When the engine is operating at a maximum engine load and the in-cylinder gas pressure reaches or exceeds a maximum pressure limit, the controller transmits one or more signals to adjust the fuel injection timing and/or adjust the pressure in the fuel accumulator to maintain NOand fuel consumption within acceptable limits.
