We study the transport of an overdamped Brownian particle moving in an asymmetric two-dimensional periodic potential in the presence of an asymmetric unbiased external force. Based on the effective potential approach, the two-dimensional system is simplified to the one-dimensional system. The expression of the net current is obtained at a quasi-steady-state limit. The competitions among the asymmetric parameter between the potentials, the coupling parameter of the potential and the temporally asymmetric parameter of the external force lead to current reversals. There may be three optimized values of temperature at which the current takes its extremum value.
