Wnet as function of phase lag and Vswc/Vswe
The annotation inside the plot next to a curved line indicate the obtained net work along this line as percentage of the optimum net work of 0.88156 J per cycle.
As Vswc/Vswe is varied the sum Vswc+Vswe stays constant at 170.37 cm³
The penalty for choosing values away from the optimum values for Vswc/Vswe and phase lag, vpl, is surprisingly small. Furthermore, whatever your choice is, under assumption of the isothermal model, your engine's efficiency is always equal to the Carnot efficiency.
