METHOD FOR DETERMINING A CONTROL VOLUME OF AN INJECTOR

摘要

The invention relates to a method and an arrangement for determining a control volume of an injector (10). The method is used in particular in an injector (10) in an internal combustion engine of a motor vehicle. The injector (10) is activated over a time period which is sufficiently short that no injection (38) of fuel into a combustion chamber (40) takes place, and that a system response follows which effects a drop in pressure as a result of the control volume flowing back, wherein the control volume is determined on the basis of the drop in the pressure.
