Abstract

In a method for setting the rotary angle position of the camshaft of a reciprocating piston internal combustion engine relative to the crankshaft, the crankshaft is connected to the camshaft by means of a triple-shaft gear mechanism. This triple-shaft gear mechanism has a drive shaft which is fixed to the crankshaft, an output shaft which is fixed to the camshaft, and an adjusting shaft which is driven by an electric motor.
