Results for thermodynamic properties of quark matter will be presented which are obtained within the framework of a two-flavor, non-local Polyakov-Nambu-Jona-Lasinio model which is based on an interaction model that reproduces the dynamical quark mass and the wave function renormalization (WFR) of the quark propagator measured in lattice QCD. In the elaboration of the corresponding phase diagrams, special attention is devoted to the determination of the critical end points, by developing a system of equations that allows to calculate numerically the corresponding mean field values together with the precise location of the critical points, the latter being tested by calculating the critical exponents. Some improvements of the model and new preliminary results will also be presented.
