Abstract
A method for controlling the total injection mass per working cycle during a multiple injection operation of a fuel injector of an internal combustion engine is provided. In the method, an injection mass difference is determined from individual injection pulse to individual injection pulse, and transferred to the next individual injection pulse, in stepwise fashion. The injection mass difference remaining in the penultimate individual injection pulse is transferred to the final individual injection pulse to achieve a total injection mass with improved tolerance.
