Abstract In intermediate energy heavy ion collision prompt particles emitted in the early stages of the reaction affect the properties of the incompletely fused composite. We have studied the entrance channel effects on preequilibrium proton emission and various observables, like temperature, residual velocity, and linear momentum transfer of the incompletely fused residue, in the framework of Promptly Emitted Particle (PEP) model. The calculated preequilibrium proton energy spectra for Oxygen and Sulphur induced reactions on various targets have been confronted with the respective experimental data and the agreement between the two has been found to be quite satisfactory. Proton multiplicity has been found to decrease/increase with the increase in target/projectile mass. Residual velocity and linear momentum transfer have been found to have weak dependance on target mass. With the increase in incident energy, the calculation predicts a tendency towards limiting the temperature of the residue for all the target masses. The limiting temperature has been found to decrease with increase in the mass of the residue which is in accordance with the experimental observations.
