摘要： In a method for operating a hydraulically controlled/regulated camshaft adjuster for internal combustion engines, in which a mechanical adjusting device designed to retard the camshaft is controlled by a piston that is hydraulically chargeable on at least one side, to which piston a pressure medium from a hydraulic circuit with a separately driven pump is supplied to an accumulator and to a valve controlled as a function of the operating point, in order to reduce harmful exhaust components when the engine starts, when the engine starts, pressure medium is supplied to the piston from an essentially full accumulator as a function of a start signal under valve control in order to advance the camshaft using the adjusting device.
