In this talk we prove a regularity result in the intrinsic directions for the solutions of the Levi equation in \(\mathbb{R}^{3}\). We denote \((x, y, t)\) the points of the space, and represent the equation in the form \[ X^{2} u+Y^{2} u-(X a+Y b) \partial_{t} u=q\left(1+a^{2}+b^{2}\right)^{3 / 2}
