ABSTRACT:
A fuel injection pump for self-igniting internal combustion engines is proposed in which a metering piston operates synchronously with the engine and a distributor operates synchronously with a pump piston. During the intake stroke of the pump piston the distributor delivers a metered injection quantity to a work chamber associated with the pump piston, and during the compression stroke of the pump piston the metered injection quantity is distributed through injection lines to the engine injection nozzles. The metering piston is disposed upstream of the distributor so that high pressure conditions do not deleteriously effect the fuel metering. The stroke of the metering piston is adjusted electrically and controlled by a microprocessor unit to which engine operating characteristics are supplied.
