1. One kind be used for especially at fuel injector (1,2 ...) the trajectory operation area proofread and correct emitted dose or injection duration (mf separately 1, mf 2, mf ;

  • Ti 1, ti 2, ti ) method, wherein Fuel injector (1,2 ...) in service determine this fuel injector (1,2 ...) actual ejection amount (mf 1, mf 2, mf ) and nominal emitted dose (mf Nom) amount deviation (△

    mf 1, △

    mf 2, △

    mf ), and By this amount deviation (△

    mf 1, △

    mf 2, △

    mf ) with this fuel injector (1,2 ...) the typical injection characteristics curve (fup specific to sparger 1, fup 2, fup ) and nominal injection characteristics curve (fup Nom) suitable, wherein at this fuel injector (1,2 ...) typical injection characteristics curve (fup) be general, as to relate to a plurality of fuel injectors injection characteristics curve.
