In contrast to standard ECSK theory with theBrans-Dicke scalar field $(\Phi)$ nonminimally coupled to the curvature scalar, an additional new pseudo scalar term $\Phi^nE^\alpha^\beta^\mu^\nu R_\alpha_\beta_\mu_\nu$ (contraction between Levi-Civita pseudo ten- sor and curvature tensor) has been included in the Lagrangian. The new term is non-zero due to the non-symmetric nature of the connec- tion and vanishes identically in the general theory of relativity. We show that there exists a nonsingular cosmological solution for a spatially fiat (k = 0) Robertson-Walker line element in the radiation era; therefore our model has no big bang.
