Abstract

A fuel injection system for internal combustion engines with a pressure step-up means is proposed, in which the fuel is pumped out of the low-pressure supplier into the injection nozzle via a feed line and is measured correctly in terms of time and quantity via a control line by the high-pressure part of the injection pump.
