- <p>The internal geothermal energy budget of Enceladus cannot be reconciled with classical orbital mechanics. Consensus models attribute the moon's tidal heating to viscoelastic dissipation generated by its 2:1 mean-motion resonance with Dione and its forced orbital eccentricity. However, current estimates of tidal dissipation fail to account for the observed $\sim$15.8 GW of continuous thermal radiation emitted from the south polar terrain, resulting in an unreconciled thermodynamic accounting deficit of $\sim$10 to 14 GW. Utilizing a continuous 26-year hourly Cartesian tensor from the JPL SAT427+ Horizons archive ($N=227,905$ coordinates, 1998--2024), this paper isolates a previously undetected 35.98-hour resonant frequency within the moon's kinematic variance. We mathematically demonstrate that this signal corresponds exactly to the Enceladus-Titan synodic intersection. Because Titan comprises $>96\%$ of the system's satellite mass, its orbit physically displaces the central Saturnian body, creating a localized kinematic shear zone relative to the system barycenter. We propose that the mechanical friction induced by intersecting this barycentric deformation provides the necessary strike-slip velocity to transduce existing orbital kinetic energy into the observed $\sim$15.8 GW of mid-infrared emission. By substituting classical diurnal tidal forces with this synodic kinematic variance, the planetary energy budget is balanced without violating the secular astrometric stability of the Saturnian system.</p>
