摘要： The present invention comprises an injection means (8) for fuel. The injection means (8) comprises a passage (17) for receiving fuel at an above-atmospheric first pressure (p 1 ), a pressure amplifier (8a) and an injection valve (8b) which is settable in an open position and a closed position. The injection valve (8b) comprises a piston element (21b), closing chamber (24) and an opening chamber (27). When fuel is intended to be injected, the pressure amplifier (8a) generates a higher second fuel pressure (p 2 ) in the opening chamber (27) so that the valve element (21b) moves towards an open position and fuel is injected. When the injection of fuel is to end, the high pressure in the opening chamber (27) is reduced and the closing chamber (24) is connected to said fuel source (7) at the first pressure (pθ so that the valve is moved towards the closed position by a combined force created by the first pressure (pi) and said spring means (25).

摘要： A method for controlling a common rail system using a signal provided from common rail pressure sensor as one input parameter to control the common rail system. When it is determined that the pressure sensor is malfunctioning, the pressure sensor input parameter is replaced with an input parameter based on the pressure sensor input parameter and a parameter representing an offset value corresponding to a difference between a theoretically correct value and the pressure sensor value. Methods for detecting a malfunctioning pressure sensor are also described: The first method by lowering the pressure until a needle no longer opens, recording the pressure output from the pressure sensor, comparing the recorded pressure value to a predetermined value and determining that a pressure sensor is malfunctioning if the recorded value and the theoretical value differs more than a predetermined threshold value. A second method by dumping fuel from at least one injector, monitoring the pressure reduction rate, recording the pressure value read when the pressure reduction rate starts to decrease and comparing the recorded pressure value to a theoretical value. A third method by increasing the pressure until a safety valve opens, recording the pressure value read in conjunction with the opening of the safety valve and comparing the recorded pressure valve to a theoretical value.

摘要： The invention relates to a fuel pump and a method for controlling a fuel pump (6). The fuel pump (6) comprises at least two pump means (6a, b) run at a mutual phase displacement such that they are able to receive fuel during different periods of time. A control unit (10) is adapted to causing a valve (11) which is only settable in an open position and a closed position to lead a desired amount of fuel to the respective pump means (6a, b). The control unit (10) is adapted accordingly to placing the valve (11) in the open position for a variable portion of said periods so that an individually controlled amount of fuel is led to the respective pump means (6a, b) during said periods. Maintenance of good efficiency of the fuel pump and low noise emissions is thus made possible in operating situations where the fuel pump delivers a reduced amount of fuel.
