when we put aluminuim hexagonal shape in fuel that may has hight temperature .. the kinetic energy decrease .. but why ?

Are you referring to benzene? If so, that's a special case. The reason is not so much the shape as the significant deshielding and aromaticity that the shape provides. The alternating pi bonds create a rigid shape. While it is true that cyclic molecules are more rigid, the rigidity tends to decrease as the molecules grow in atomic weight.
If you think about it, this rigid shape, of benzene, doesn't allow for transbond movement of other cyclics, only for movement of the complete molecule. For this reason the kinetic energy of the structure is significantly lower than other molecules of this class (naphthalene, anthracene, etc).

More sides and angles?
