%X This study investigates the diffusive motion of a Brownian particle in a 2D tilted periodic potential, where bias force is exerted in the <em>x</em> direction. The dimension effect is revealed by simulating the Langevin equation. The diffusion coefficient in <em>x</em> and <em>y</em> directions is a nonmonotonic function of the bias force, and a massive enhancement is observed in <em>x</em> and<em> y</em> directions in comparison with the case without a tilt in <em>x</em> direction. The underlying physical mechanism is explored.
