Propulsion, drivetrain, and transmission

Powertrain systems include propulsion, drivetrain, and transmission subsystems. To configure the drivetrain subsystem, you can use the limited slip or open differential blocks. The propulsion blocks include mapped motor, compression-ignition (CI) engine, and spark-ignition (SI) engine blocks. For the transmission subsystem, you can use the ideal fixed gear transmission block.

Engine Calibration Maps

The Mapped CI Engine and Mapped SI Engine blocks models use calibration maps developed with the Model-Based Calibration Toolbox™ and measured engine performance data.
