1. An engine assembly comprising:

  • an internal combustion engine including an engine block having at least one cylinder, at least one piston moveable within the at least one cylinder;

    an intake manifold and an exhaust manifold, each fluidly connected to the at least one cylinder and defining an intake manifold pressure (pi) and exhaust manifold pressure (pe), respectively;

    a controller operatively connected to the internal combustion engine and configured to receive a torque request (TR);

    wherein the controller is programmed to determine a desired fuel mass (mf) for controlling a torque output of the internal combustion engine, the desired fuel mass (mf) being based at least partially on the torque request (TR), the intake manifold pressure (pi), the exhaust manifold pressure (pe) and a log-scaled pressure-volume (PV) diagram of the at least one cylinder.
