Test Cell Naturally Aspirated SI

×

Test model for the entire engine system with the dynamic measured signal as input. To create an experiment, extend from this model and redeclare the engine with a configured one. Then chose parameters and initial values in the drop-down menus in the engine parameter dialog. These are best created by using the supplied matlab functions.

The file with measurement signals is defined by assigning the filename to the parameter BCFile (this is an experiment level parameter and is modified by right-clicking on the experiment model in the package browser and choosing "Parameters").

Torque Ramp Turbo Charged Engine

×

This is an example of a transient torque response at constant engine speed in a turbo-charged Diesel engine. A PID controller is implemented to control the fuel injection.Additionally, an air-fuel excess ratio threshold (λ = 1.3) is used to limit the fuel injection.

In this simple experiment the engine speed and other inputs, except fuel flow, is kept constant. The EGR valve is closed completely. The turbo speed is initialized at a higher speed than steady-state for the initial operating point. At t=50 the torque setpoint is increased from 0 to 2350 Nm. The generated torque and turbo speed will gradually increase as fuel injection increases.
