ABSTRACT:
A fuel injection system for a multi-cylinder aircraft engine in which, in order to secure the fuel supply, a pressure-measuring device is connected to the feed line leading from the fuel tank to the fuel quantity distributor, into which are installed two parallel fuel pumps and a fuel filter; this pressure-measuring device in case of a predetermined pressure drop switches on the fuel pump which previously was not in operation; in case of an excessive pressure difference at the fuel filter which is measured by pressure-measuring device upstream and downstream of the filter, an electromagnetic valve installed into a bypass line to the fuel filter is opened; the soiling degree of the fuel filter is indicated by a hydraulically actuated difference pressure-measuring device with pressure limitation.
