Abstract
A fuel injection pump in which the fuel metering is performed with the aid of an electromechanical fuel metering device with fuel which is at low pressure, and the disposition of the injection with respect to the full compression stroke of the pump piston of the fuel injection pump can be varied by means of a variable withdrawal of fuel at the end of the compression stroke and the resupply of the withdrawn fuel during the intake stroke of the pump piston. A desired injection characteristic can thereby be attained, or a desired, specified portion of a cam elevation curve at which injection is supposed to take place can be selected.
