1. A method for regulating fuel injection quantities of an injector of an internal combustion engine, comprising:

  • implementing a test cycle including a test injection pulse during a normal fired combustion operating state of the internal combustion engine,detecting a rotational speed signal of the internal combustion engine caused by the test injection pulse,using a processor, determining a crankshaft acceleration based on the detected rotational speed signal caused by the test injection pulse,using the processor, determining an actual injected fuel quantity of the injector based on the determined crankshaft acceleration associated with the test injection pulse, andusing the processor, adjusting actuation data of the injector for subsequent fuel injections based on the determined actual injected fuel quantity.
