Abstract
An engine assembly includes an internal combustion engine with an engine block having at least one cylinder and at least one piston moveable within the at least one cylinder. A crankshaft is moveable to define a plurality of crank angles (CA) from a bore axis defined by the cylinder to a crank axis defined by the crankshaft. A controller is operatively connected to the internal combustion engine and configured to receive a torque request (T). The controller is programmed to determine a desired combustion phasing (CA) for controlling a torque output of the internal combustion engine. The desired combustion phasing is based at least partially on the torque request (T) and a pressure-volume (PV) diagram of the at least one cylinder.
