Abstract (en)

[origin: CA3045361A1] The invention relates to a fuel supply system, in particular a common-rail fuel supply system, of an internal combustion engine, which in particular is designed as a large diesel internal combustion engine or marine diesel internal combustion engine, comprising a low-pressure region (4), a high-pressure region (6), a pumping device (3), having at least one low-pressure pump (5) and at least one high-pressure pump (2), for conveying fuel from the low-pressure region (4) of the fuel supply system into the high-pressure region (6) of the fuel supply system, wherein a pressure accumulator system (7) permanently under high pressure is provided between the pumping device (3) and injectors associated with cylinders and has a plurality of distributor units (9), wherein, between the or each low-pressure pump (5) and the or each high-pressure pump (2), a fuel distributor block (13) is provided, to which fuel can be supplied from the or each low-pressure pump (5) and from which fuel can be supplied to the or each high-pressure pump (2) and to which fuel leakage can be supplied from the distributor units (9) and the pumping device (3), and wherein the fuel distributor block (13) has a fuel leakage collection line for the fuel leakage supplied to the fuel distributor block (13), which fuel leakage collection line has a narrow point or choke and a bypass around the narrow point or choke and a leakage sensor in the region of the bypass, wherein the narrow point or choke is dimensioned in such a way that all fuel leakage flows through the narrow point or choke if the fuel leakage conducted via the fuel leakage collection line is less than a limit value, whereas part of the fuel leakage flows through the bypass and thus across the leakage sensor if the fuel leakage conducted via the fuel leakage collection line is greater than the limit value.
