The invention is related to emulsions containing surface-modified inorganic nanoparticles. Each dispensing container is adapted to hold granular material and in one embodiment includes a pressure actuated valve. The command value signals Xu1, Xv1, and Xw1 are continuously at \u201c0\u201d for a predetermined period, and are continuously at \u201c2\u201d for another period. A second vibration isolation member may be sandwiched between a seat of the vehicle and an upper surface of the fuel tank to further damp vibrations.
