Affine congruences and rational points on a certain cubic surface

##### Abstract

We establish estimates for the number of solutions of certain affine congruences. These estimates are then used to prove Manin’s conjecture for a cubic surface split over $ℚ$ whose singularity type is ${D}_{4}$. This improves on a result of Browning and answers a problem posed by Tschinkel.
