This model belongs to the map-based models of power train components.
It models an Internal Combustion Engine, neglecting any dynamics except that related with its rotor inertia.
The input signal is a normalised request (0..1).
The generated torque is the product of the maximum deliverable torque at the actual engine speed, defined by means of a table, and the normalised input signal
From the generated torque and speed the fuel consumption is computed.
