A control system for a motor vehicle provided with a continuously variable transmission which has a transmission ratio control valve having a spool for controlling the transmission ratio. During the acceleration of the vehicle, the transmission ratio is quickly reduced in a low vehicle speed range, whereby speed of an engine is kept low compared with a high vehicle speed range.

The formation efficiency of pasted positive plates of a lead-acid battery is greatly enhanced by providing in situ a layer of lead dioxide (PbO2) on the pasted plate surfaces prior to formation. The PbO2 layer is preferably formed by treating the surfaces of the plates with an ozone-enriched gas to convert a portion of the poorly conductive positive active precursor material (nPbO.PbSO4) to electr...
