Fuel supply system for IC engine

摘要

The fuel feed system has a tank, two fuel pumps (6,12) and at least one valve. The first pump brings the fuel from the tank to a supply pipe (10) and the second pump delivers it from here to the injector where it can enter the combustion chamber indirectly. A valve (30) influencing the feed pressure in the supply pipe changes this pressure as a function of engine conditions. It acts electrically and possesses a flow resistance. It is located in another pipe (22) between the tank and the supply pipe. Along with this valve is a pressure control valve (26) in series.
