Description: We study models with a generalized inhomogeneous equation of state fluids, in the context of singular inflation, focusing to so-called TypeIV singular evolution. In the simplest case, this cosmological fluid is described by an equation of state with constant w, and therefore a direct modification of this constant wfluidis achieved by using a generalized form of an equation of state. We investigate from which models with generalized phenomenological quation of state, a TypeIV singular inflation can be generated and what the phenomenological implications of this ingularity would be. We support our results with illustrative examples and we also study the impact of the TypeIV singularities on the slow-roll parameters and on the observational inflationary indices, showing the consistency with Planck mission results. The unification of singular inflation with singular dark energy era for specific generalized fluids is also proposed.
