Abstract
The invention relates to a fuel injection system for use in internal combustion engines having delivery units for delivering fuel from a fuel reservoir in order to supply at least one high-pressure line to the cylinders of the engine. The at least one high-pressure line supplies a number of fuel injectors, which each include an injector nozzle that supplies fuel to a combustion chamber of the engine and includes line segments that connect the individual fuel injectors to one another. The injector bodies of the fuel injectors each have an accumulator chamber integrated into them.
Claims13
A fuel injection system for use in internal combustion engines, that has delivery units (2, 3) for delivering fuel from a fuel reservoir (1) in order to supply at least one high-pressure line (9, 10) to the cylinders of the engine, the system comprising
- the at least one high-pressure line (9, 10) supplying a plurality of fuel injectors (11), which include an injector nozzle (16) that supplies fuel to a combustion chamber of the engine,
- the at least one high-pressure line (9, 10) including line segments (17, 17.1, 17.2) that connect the individual fuel injectors (11) to one another, the fuel injectors each having an accumulator chamber (36, 36.1) integrated into an injector housing (20), wherein each fuel injector (11) includes a head region (15) having a conduit (44) extending through the head region, the conduit (44) having an inlet connected to one line segment and an outlet connected to another line segment, and wherein the head region (15) of the fuel injector (11) is embodied as an insert piece (51), which is connected to the injector body (20) in a sealed fashion.
