<p>As information relating to the characteristics of the spray form of an injector (23), "penetration information", "spray angle information", and "injection angle information" are attached to the injector (23) by means of a QR code (registered trademark) (25). When the injector (23) is mounted, the QR code (25) is read, and the injector control amount is corrected according to the characteristics of the spray form. As the injector (23) has a smaller penetration characteristic, the injection timing of pilot injection is shifted further to the advance side. As the injector (23) has a smaller spray angle characteristic, the injection amount of pilot injection is made larger. As the injector (23) has a smaller injection angle characteristic, the injection timing of main injection is shifted further to the advance side.</p> |
