Results of a systematic investigation of the vapour-liquid equilibria of 38individual two-centre Lennard-Jones plus axial pointdipole model fluids (2CLJD)are reported over a range of reduced dipolar momentum 0 $\le \mu^{*2} \le$ 20and of reduced elongation 0 $\le$ L* $\le$ 1.0. Temperatures investigated arefrom about 55 % to about 95 % of the critical temperature of each fluid. TheNpT+Test Particle Method is used for the generation of vapour pressures,saturated densities, and saturated enthalpies. For the lowest temperatures,these data are calculated with highly accurate chemical potentials obtainedfrom the gradual insertion method. Critical temperatures $T*_c$ and densities$\rho*_c$ are obtained from Guggenheim's equations. Empirical correlations forcritical data $T*_c$ and $\rho*_c$ as well as for saturated densities $\rho'*$,$\rho''*$, and vapour pressures $p*_\sigma$ are developed as global functionsof the model parameters. They describe the simulation data generally withintheir statistical uncertainties. Critical pressures and acentric factors of the2CLJD fluid can be calculated from these correlations. The present results area sound basis for adjustments of the model parameters $\mu^{*2}$, $L*$,$\sigma$, and $\epsilon$ to experimental VLE data of real fluids.
