Abstract (en)

[origin: EP1793119A1] The line connects an injector of a fuel injection unit with a high pressure accumulator (16) or a high pressure pump. A flow cross section constriction (36) is arranged between the injector and the accumulator. The constriction is formed in an end area of the fuel high pressure line through reduction of an inner cross section of the fuel high pressure line compared to another inner cross section, where the end area faces a high pressure accumulator or high pressure pump.
