Limitation apparatus for full-load injection quantity in a supercharged internal combustion engine with fuel injection

An apparatus for the limitation of the full-load injection quantity in a supercharged internal combustion engine with fuel injection including an injection pump having a supply quantity adjustment member, with two pneumatic control elements, one control element responds to the pressure differential between charge and atmospheric pressure to effect a charge-pressure-dependent limitation of the full-load injection quantity, and another control element embodied as a barometric cell is arranged to limit the full-load injection quantity in dependence on atmospheric pressure and both control elements act on said supply quantity adjustment member of said injection pump, and with a full-load stop which is disengageable for the attainment of an additional starting quantity which is greater than the full-load injection quantity, further wherein each of said control elements acts at least indirectly via deflecting elements on said full-load stop independently of one another and alternately relieving each other so that only one of said control elements determines the maximal full-load setting of said full-load stop for said supply quantity adjustment member of said injection pump and means disengaging said full-load stop when the engine rpm value.
