We consider the spinless fermion model with hard-core repulsive potential between particles extended on a few lattice sites . The Luttinger-liquid behavior is studied for different values of a hard-core radius. We derive a critical exponent of the one-particle correlation function for an arbitrary electron density and coupling constant. Our results show that at high density the behavior of fermions can be described as a strongly interacting Luttinger liquid with . As a result, the residual Fermi surface disappears.
