Defines the vehicle FMEP model.

Parameters:
  • full_bmep_curve (function) – Vehicle full bmep curve.
  • engine_max_speed (float) – Maximum allowed engine speed [RPM].
  • engine_stroke (float) – Engine stroke [mm].
  • active_cylinder_ratios (tuple[float]) – Possible active cylinder ratios [-].
  • engine_has_cylinder_deactivation (bool) – Does the engine have cylinder deactivation technology?
  • engine_has_variable_valve_actuation (bool) – Does the engine feature variable valve actuation? [-].
  • has_lean_burn (bool) – Does the engine have lean burn technology?
  • has_exhausted_gas_recirculation (bool) – Does the engine have exhaust gas recirculation technology?
  • has_selective_catalytic_reduction (bool) – Does the engine have selective catalytic reduction technology?
  • engine_type (str) – Engine type (positive turbo, positive natural aspiration, compression).
  • idle_engine_speed ((float, float)) – Engine speed idle median and std [RPM].
  • after_treatment_temperature_threshold ((float, float)) – Engine coolant temperature threshold when the after treatment system is warm [°C].
Returns:

Vehicle FMEP model.
Return type:
