Abstract (en)
[origin: WO2004009990A1] The invention relates to a fuel circuit in a common-rail injection system, comprising a low-pressure pump (1), a high pressure pump (3) and a bypass line (5), for the injection rail (4), whereby said bypass line (5) has a second fuel filter (7.2) and a heat exchanger (6). The bypass line (5) returns excess fuel into the fuel line (2) between the low pressure pump (1) and the high pressure pump (3).
