摘要：A method of producing fuel injectors (1) for internal combustion engines (E) provides for establishing a working life (LF) of each injector (1) conforming with the working life of the internal combustion engine (E) on which it is installed. Each injector (1) has an injector body (2) having a seat (5); a valve body (17) housed inside the seat (5) so as to form an annular chamber (29), for receiving high-pressure fuel, and a gap (M) communicating with the annular chamber (29); and a seal (32) housed inside the annular chamber (29) to seal the gap (M). The seal (32) is sized as a function of the permanent deformation to which the seal (32) is subjected during use of the injector (1), so as to achieve a working life (LF) of the injector (1) substantially equal to the working life of the engine (E). <IMAGE>
