摘要：A method of operating a fuel injector of an internal combustion engine includessetting a value of a target fuel quantity to be injected by the fuel injector, initializing avalue of a fuel quantity requested from the fuel injector to the value of the target fuel
quantity, and correcting the value of the requested fuel quantity. A first learning cycle isperformed to correct the value of the requested fuel quantity in which a differencebetween the target fuel quantity and the injected fuel quantity is calculated and addedto the requested fuel quantity to provide a corrected value. The corrected value of therequested fuel quantity is used to determine a reference value of an energizing time thatcauses the fuel injector to inject a fuel quantity corresponding to the target fuel quantity.The fuel injector is operated based on the determined reference value of the energizingtime.
