As i have prepared second generation model of engine in SIMULINK  and i want to apply force (if Possible Pneumatic force -compressed air flow) on piston and want to observe dynamics of crank

Thank you sir for your fast reply As i am Little bit aware of Sim scape

sir in Pneumatic Piston Chamber - inbuilt piston chamber is there. In my case i want output of crank shaft torque by supplying compressed air to piston head over there expansion of air occurs and develop forces and push the piston and through connecting rod crank rotates.

& I have crated piston cylinder connecting rod crank assembly in CAD software mechanism and imported in MATLAB simulink. As here with i attached file .mdl file also.
