Abstract (en)
[origin: WO2014206924A1] The invention relates to a method for pairing at least two injectors (1), in particular two fuel injectors (1) for a direct injection system of an internal combustion engine, wherein a criterion for the pairing of the at least two injectors (1) is a total leakage (L212) and/or a pressure difference (Δρ = p12∞-p∞, Δρ = p22-p∞) at a transfer pin (212) of the respective injector (1). The invention further relates to a method for producing an injector (1), in particular a fuel injector (1) for a direct injection system of an internal combustion engine, wherein at least two instances of mechanical backlash (110/120, 210/212, 220/222), in particular instances of pairing backlash (110/120, 210/212, 220/222), that are relevant to injection amounts, leakage amounts (L112, L212, L222), and/or pressure differences (Δρ = pR-p12≈ /= Δρ = pR-p22) of the injector (1) are paired with each other.
