In this paper a new finite difference scheme called Modified Crank Nicolson Type (MCNT)method is proposed to solve one dimensional non linear Burgers equation. The new scheme is obtained by discretizing the nonlinear term uux explicitly, u is approximated at t=tn+1 and ux by central difference at t = tn. The stability and convergence of the scheme is analysed. The method is shown to be first order accurate in time and second order accurate inspace. The solutions of Burgers equation obtained by MCNT are compared with the exact and numerical solutionsof Burgers equation available in the literature. For comparisons of numerical solutions with existing methods three test problems are tested.The L2 norm and L norm are used to compare the errors in the solutions. The solutions of Burgers equations are plotted at different time steps for different values of constant of diffusivity k.
