Method of determining amount of fuel delivered by fuel injector

The invention relates to a method for determining an amount of fuel (Q) delivered by a fuel injector for an internal combustion engine by means of a sensor which is provided to detect an opening and /or closing of the fuel injector, wherein detects a signal waveform of the sensor during operation of the fuel injector is determined, and based on a value of a signal characteristic characteristic (M) using a relationship (F) of values of the characteristic parameter (M) and discharged fuel quantity (Q), the amount of fuel emitted by the fuel injector (10) is determined. 本发明涉及种借助传感器来确定由燃料喷射器所排出的燃料量(Q)的方法，所述燃料喷射器用于内燃机，所述传感器被设置用于，检测所述燃料喷射器的打开和/或关闭，其中，在所述燃料喷射器的运行期间，检测所述传感器的信号变化过程，并且其中，参照对于所述信号变化过程来说表示特征的参数(M)的值，在使用所述表示特征的参数的值(M)与所排出的燃料量(Q)的关系(F)的情况下，确定由所述燃料喷射器(10)所排出的所述燃料量。
