Abstract

A method is provided for pairing at least two injectors, e.g., two fuel injectors for a direct injection system of an internal combustion engine, wherein a criterion for the pairing of the at least two injectors is a total leakage and/or a pressure difference at a transfer pin of the respective injector. A method for producing an injector, e.g., a fuel injector for a direct injection system of an internal combustion engine, is also provided, wherein at least two instances of mechanical backlash, e.g., instances of pairing backlash, that are relevant to injection amounts, leakage amounts, and/or pressure differences of the injector are paired with each other.
