Abstract: In this letter we present a new form of the well known Chaplygin gas model byintroducing inhomogeneity in the EOS. This model explains $\omega=-1$ crossing.Also we have given a graphical representation of the model using $\{r,s\}$parameters. We have also considered an interaction of this model with thescalar field by introducing a phenomenological coupling function and have shownthat the potential decays with time.
