Engine Timing Simulation
This demonstration shows how to use Triggered subsystems to model engine timing. Different subsystems in the diagram model the mathmatical representation of various automotive systems, include the following.
The valve timing subsystem generates a signal that triggers the Compression subsystem twice per revolution of the crank (calculated from the crank speed.)
A throttle schedule (in angles) from the Step block labeled "throttle" on the left side of the diagram drives the simulation.
After running the simulation, the Scopes show the engine speed and the throttle angle compared to the load torque.
