METHOD FOR INDIVIDUALIZING INJECTOR FOR INTERNAL COMBUSTION ENGINE WITH PIEZOELECTRIC ELEMENT, CONTROL METHOD FOR PIEZOELECTRIC ELEMENT, INJECTOR AND INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To facilitate the use of knowledge obtained by describing the actual characteristics of an injector with a piezoelectric element in a more detailed manner. SOLUTION: The stroke of the piezoelectric element 22 is detected 28 depending on applied voltage, and a code 24 is formed in accordance with a detected voltage/stroke ratio to characterize 40 the injector 14.
