Method for producing an injector

A method for producing an injector, comprising the steps of:

• assembling a first module comprising a lift actuating drive,
• assembling a second module comprising a nozzle arrangement,
• determining at least one value of at least one characteristic variable for the first module by appropriate activation of the lift actuating drive,
• assigning the first module to one of a number of classes as a function of the at least one value of the at least one characteristic variable,
• determining at least one value of at least one characteristic variable for the second module by appropriate actuation of the nozzle arrangement,
• assigning the second module to one of a number of classes as a function of the at least one value of the at least one characteristic variable, and
• pairing and assembling a first module with a second module of the same class, respectively, wherein a predetermined lift of the lift actuating drive is set for the first module under the influence of a predetermined counter-force acting on the lift actuating drive and a variable, which is characteristic of the electrical energy that has to be supplied to the lift actuating drive for this purpose is determined as the characteristic variable.

A method for producing an injector, comprising the steps of:

• assembling a first module comprising an injector housing and a lift actuating drive,
• assembling a second module comprising a nozzle body, a nozzle needle and a reset means for the nozzle needle,
• determining at least one value of at least one characteristic variable for the first module by appropriate activation of the lift actuating drive,
• assigning the first module to one of a number of classes as a function of the at least one value of the at least one characteristic variable,
