Abstract:
To provide a fuel supply device which can collect a sample of proper fuel when analyzing a component in the fuel being a cause of a malfunction of fuel system apparatuses of an internal combustion engine.SOLUTION: A fuel supply device 1 as a fuel sampling system comprises: a fuel sampling device 6 arranged in a position between a fuel filter 5 and an engine 100 on a supply line L1, and collecting a part of fuel supplied to the engine 100 to a fuel storage vessel as a fuel sample; an abnormality detection device (machine controller 22) for detecting an abnormality which occurs on the supply line L1; and a control device 20 for controlling fuel supply to the engine 100, and controlling the collection of the fuel sample by the fuel sampling device 6. When the abnormality is detected by the abnormality detection device at the fuel supply, the control device 20 starts to collect the fuel sample by the fuel sampling device 6, and when the fuel sample collected to the fuel storage vessel reaches a prescribed quantity, the control device stops the collection of the fuel sample.SELECTED DRAWING: Figure 1
