Abstract: A method for operating an internal combustion engine, wherein a valve of a cylinder is opened by a cam of a camshaft within a duty cycle of the engine, and a specified quantity of fuel is supplied to the cylinder. A dimension of the cam and/or a position of the cam on the camshaft is measured after the cam and/or the camshaft has been produced. The dimension, position, and/or a characteristic variable ascertained therefrom is stored, and the quantity of the fuel to be fed within the duty cycle is determined dependent on the stored dimension, position, and/or characteristic variable calculated therefrom. An internal combustion engine is also described for carrying out the method according to the invention.
