Large amplitude solitary waves are investigated in a dusty plasma containing electrons, positive ions, negative ions, and positively charged dust grains [N. D'Angelo, J. Phys. D 37, 860 (2004)] by the Sagdeev potential. Numerical investigations related to Q machine dusty plasma with a positive charge reveal that the nonlinear dust acoustic wave possesses only a supersonic compressive soliton. The range of Mach numbers where such solitary waves exist is also investigated.
