Method For Producing Injectors, In Particular Fuel Injectors

摘要

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.

1. A method for producing a plurality of fuel injectors for motor vehicles, the method comprising:
assembling multiple instances of at least two components into a plurality of provisional pairings; for each provisional pairing of the instances of the at least two components, determining a metric resulting from the provisional pairing, the metric comprising a total leakage or a pressure difference at a transmission pin of a fuel injector; assembling a plurality of fuel injectors, including selecting an actual pairing of instances of the at least two components for each fuel injector for each injector based on the determined metrics resulting from the provisional pairings, such that the metric resulting from the actual selected pairing of instances of the at least two components is approximately the same for all of the fuel injectors.
