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, Tbrake=fTnf(F,N), where:

  • Tq = Tbrake 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.
