    摘要: The invention concerns a fuel system (4) that comprises a first fuel tank (20) and a second fuel tank (22). The fuel is conducted from the first fuel tank (20) to a high-pressure system (19). A main feed pump (26) feeds fuel from the first fuel tank (20) via a second line (40) and a transfer pump (28) feeds fuel from the second fuel tank (22) to the first fuel tank (20) via the first fuel line (36). A first electric motor (M1) drives the main feed pump (26), and is arranged in the first fuel tank (20). The first fuel tank (20) holds a smaller volume than the second fuel tank (22). A fuel return line (13) is arranged so as to return pressurized fuel from the high-pressure system (19) to the first fuel tank (20). The fuel system (4) further comprises an arrangement for controlling the fuel temperature in the first fuel tank (20) by controlling the flow of fuel to the first fuel tank (20). The invention also concerns a combustion engine (20) and a vehicle (1) that contains the system, and a method for controlling a fuel system (4).

    摘要: A fuel system for an internal combustion engine is provided, which comprises a first fuel tank, a fuel filter device, arranged between a low pressure pump operated by an electric motor and a high pressure pump, a first fuel conduit, through which the low pressure pump is arranged to supply fuel to the fuel filter device, and a control device, arranged in connection with an electric motor operating the low pressure pump. An overflow conduit is arranged in connection with a deaeration outlet, arranged in the fuel filter device and the first fuel tank, and the control device is arranged to control the electric motor, in such a way that the low pressure pump is active when the internal combustion engine is turned off for a limited period, whereby fuel may flow from the fuel filter device via the deaeration outlet and the overflow conduit, back to the first fuel tank.

    摘要: A fuel system (4) for a combustion engine (2) comprises a first fuel tank (20), a second fuel tank (22), a first fuel pipe (36) arranged in connection with the first fuel tank (20) and the second fuel tank (22), a second fuel pipe (40) arranged in connection with the first fuel tank (20), a main feed pump (26), and a transfer pump (28). The main feed pump (26) feeds fuel from the first fuel tank (20) through the second fuel pipe (40), and the transfer pump (28) feeds fuel from the second fuel tank (22) to the first fuel tank (20) via the first fuel pipe (36). A valve (32) is arranged downstream of the transfer pump (28). The valve (32) comprises an inlet connected with the transfer pump (28), a first outlet connected with the first fuel pipe (36) and a second outlet connected with the second fuel pipe (40). The fuel system reduces the risk of insufficient or loss of fuel supply to the combustion engine in the event of an operational disruption, and enables a method for continued operation, albeit with potentially reduced power. This also secures the operation of the combustion engine (2) and a vehicle equipped with such a fuel system.
