The purpose of this paper is to develop improved finite difference schemes. We firstly propose to use the fourth order TVD flux presented in  as the building block in ENO schemes for scalar problems. A way to extend this scheme and the scheme  to general systems of nonlinear hyperbolic conservation laws, in one and two dimensions, is discussed in details. A semi-discrete version of the two schemes are presented. The performance of the schemes is assessed by solving test problems for the Euler equations of gas dynamics in one and two dimensions. We use exact solutions and other results to validate the results.
