CI Engine Simple Torque Model

For the simple torque lookup table model, the CI engine uses a lookup table is a function of engine speed and injected fuel mass, $T_{b r a k e} = f_{T n f} (F, N)$ , where:

Tq = T_brake is engine brake torque after accounting for engine mechanical and pumping friction effects, in N·m.
F is injected fuel mass, in mg per injection.
N is engine speed, in rpm.
