Propulsion systems in powertrains include internal combustion spark-ignition (SI) engines, compression-ignition (CI) engines, and electric motors. Use the propulsion blocks to assemble engine subsystems and controllers for hardware-in-the-loop (HIL) engine control design, vehicle-level fuel economy, and performance simulations.

Internal Combustion Engines
- SI Core Engine Air Mass Flow and Torque Production
The SI engine air mass flow calculation uses either a speed-density or a dual-independent cam phaser model. To calculate the brake torque, the SI engine uses either a simple torque or a structured torque model.
- CI Core Engine Air Mass Flow and Torque Production
The CI engine air mass flow calculation uses a speed-density model. To calculate the brake torque, you can configure the CI engine to use a simple torque or a structured torque model.
