Abstract (en)
[origin: EP1132604A2] A method of monitoring the fuel injection of a combustion engine (10), in which the amount of fuel to be injected (MF_IS) is regulated by the revs. (N_IST) of the combustion engine (10), in speed (revs) regulated operational states of the engine (10). The amount of fuel to be injected (MF_IS) is ascertained and is compared with given threshold values (MF_MAX,MF_MIN) and a faulty injection is concluded, when the injected amount of fuel (MF_IS) lies outside a range limited by the threshold values (MF_MAX,MF_MIN). The speed (revs) regulated operational state of the combustion engine is the idling state.
