In this way, the control will no longer be exercised in a manner of following after the variable loading conditions of the marine diesel engine, and the control of the fuel injection amount can be exercised efficiently.
  • the above change of the rotational speed is measured for a predetermined time period in relation to the fuel injection amount, the regularity of the change also being estimated, the subsequent variation cycle is predicted, and thus the control can be exercised so as to always keep a constant rotational speed of the screw propeller.
  • a set rotational speed of the marine diesel engine can be kept because of the optimal fuel injection amount as described above.
  • the fuel injection valve open/close mechanism comprises: a liquid pressure cylinder, a check valve mechanism for providing oil pressure switchably in separated chambers formed on both sides of a piston of said liquid pressure cylinder, a bidirectional pump with a motor for delivering a pressurized fluid to said separated chambers via said check valve mechanism, and a driver for controlling the operation of said bidirectional pump, the pump to provide oil pressure is separated from the rotating shaft of the marine diesel engine, and the fuel injection amount can thus be controlled freely irrespective of the rotational speed of the marine diesel engine.
  • the rotational speed of the marine diesel engine at the time of fuel injection can be predicted to freely open or close the opening of the fuel injection valve as described above.
  • the oil pressure pump can be operated in response to the loading condition of the marine diesel engine wherein the rotation of the oil pressure pump is increased when the rotation of the marine diesel engine is in a decreased state or conversely the rotation of the oil pressure pump is decreased when the rotation of the marine diesel engine is in an increased state, and the pressurized oil from the oil pressure pump will no longer be returned unnecessarily to the tank as in the conventional art.
  • the difference between the control signal for the opening of the fuel injection valve and the actual opening of the fuel injection valve is reduced so that a constant rotational speed of the marine diesel engine can be kept more properly.
  • the first controller inputs a set rotational speed of the marine diesel engine, the accrual rotational speed of the marine diesel engine, and the actual opening of the fuel injection valve, and outputs a primary control signal for the opening of the fuel injection valve.
  • the first controller calculates the necessary opening of the fuel injection valve using the difference between the set rotational speed and the actual rotational speed of the marine diesel engine, and outputs the primary control signal using the difference between the calculated opening of the fuel injection valve and the actual opening of the fuel injection valve.
  • the second controller inputs the above primary control signal for the opening of the fuel injection valve, and the actual opening of the fuel injection valve, and outputs a secondary control signal for the opening of the fuel injection valve.
  • the second controller inputs the opening of the fuel injection valve required according to the primary control signal, and the actual opening of the fuel injection valve, and outputs the secondary control signal so as to compensate the difference.
  • the control can be exercised in such a way that the difference between the opening of the fuel injection valve required according to the control signal for the fuel injection valve and the actual opening of the fuel injection valve is compensated, and a constant rotational speed of the marine diesel engine can be kept more properly according to the present invention.

  • the second sensor 8 is made to detect the opening of the fuel injection valve 7 indirectly by detecting the travel distance of the piston of the liquid pressure cylinder of the fuel injection valve open/close mechanism 3 rather than detecting the opening of the fuel injection valve 7 directly, as will be described later.
  • the fuel injection valve open/close mechanism 3 comprises a liquid pressure cylinder 9 for driving the fuel injection valve 7; a check valve mechanism 12 for providing oil pressure switchably in separated chambers 11 formed on both sides of a piston 10 of the liquid pressure cylinder 9; a bidirectional pump 13 for delivering a pressurized working fluid to the separated chambers 11 via the check valve mechanism 12; a motor 14 for driving the bidirectional pump 13; and a driver 15 for controlling the operation of the bidirectional pump 13 and the motor 14.

  • pipes 19 and 20 are provided respectively to direct the pressurized fluid to push up (open) the other check valve.
  • the fuel injection amount control mechanism 4 comprises: a first controller 21 for inputting a set rotational speed of the marine diesel engine as a target rotational speed, the rotational speed of the marine diesel engine 2 detected by the first sensor 6, and the data of the opening of the fuel injection valve 7 detected by the second sensor 8, and for outputting a primary control signal for a target opening of the fuel injection valve; and a second controller 22 for inputting said primary control signal from the first controller 21, and a signal of the opening of the fuel injection valve 7 from the second sensor 8, and outputting a secondary control signal so as to match the actual opening of the fuel injection valve 7 with the target opening of the fuel injection valve.
  • the control exercised by the secondary control signal in addition to the primary control signal allows the opening of the fuel injection valve to be exactly matched with the target opening of the fuel injection valve by the second sensor 8 detecting the actual travel distance of the piston of the liquid pressure cylinder 9, whereas if the primary control signal inputs to the driver 15 of the fuel injection valve open/close mechanism 3 the target fuel injection amount, i.e. the control signal for the opening of the fuel injection valve 7, it would be difficult to control the exact opening of the fuel injection valve 7 solely by the rotation of the bidirectional pump 13.
  • the operation of the fuel injection valve open/close mechanism 3 is as follows.
  • the control signal from the driver 15 allows the motor 14 to run, such as starting, stopping, and rotating in the normal/reverse direction.
  • the bidirectional pump 13 is driven by the motor 14 to draw the working fluid from the tank 18 and deliver the pressurized working fluid to the pipe system on the upstream side of the check valve 16. From the pipe system on the upstream side of the check valve 16, the pressurized working fluid flows into the upper chamber of the separated chambers 11 of the liquid pressure cylinder 9 and pushes down the piston 10.
  • the pressurized working fluid in the pipe system on the upstream side of the check valve 16 is made to pass at the same time through the pipe 19 and push up the valve body of the check valve 17 to open the check valve 17.
  • the piston 10 With the piston 10 being pushed down, the working fluid in the lower chamber of the separated chambers 11 of the liquid pressure cylinder 9 flows out to the pipe system on the upstream side of the check valve 17. Since the check valve 17 is open, the working fluid which has flowed out to the pipe system on the upstream side of the check valve 17 flows out to the tank 18 through the check valve 17.
  • the fuel injection valve 7 is opened or closed via the rod of the piston 10.
  • the fuel injection control i.e. a method for controlling the fuel injection so as to match the loading condition of the marine diesel engine at the time of fuel injection, according to the present invention.
  • the fuel injection control device 1 measures the fuel injection amount and the rotational speed of the marine diesel engine a prescribed number of times at prescribed time intervals and inputs the measurements.
  • the data of the aforementioned fuel injection amount and rotational speed of the marine diesel engine are collected by the first sensor 6 and the second sensor 8.
  • the data of the fuel injection amount and the rotational speed of the marine diesel engine are corresponded to each other, as shown in Fig. 2 for example, and stored in a storage device, not shown, of the first controller 21.
  • the rotational speed of the marine diesel engine due to the fuel injection amount at present can be determined.
  • the coefficients a, b not only depend on the marine diesel engine but also change according to the loading conditions of the marine diesel engine. Accordingly, the first controller 21 of the fuel injection control device 1 calculates the above coefficients a, b while inputting the fuel injection amount and the rotational speed of the marine diesel engine as needed.
  • the coefficient matrix A is determined as follows.
  • A X T ⁇ X - 1 ⁇ X T ⁇ Y
  • an appropriate fuel amount for the loading condition of the marine diesel engine at the time of fuel injection can be injected by exercising the fuel injection amount control that will no longer be lagged behind the actual loading condition of the marine diesel engine as the conventional fuel injection control is, and the rotational speed of the marine diesel engine can be efficiently kept at a target rotational speed, and also unstable behaviors of the engine caused by opening and closing the fuel injection valve behind the actual loading condition can be prevented. Because a proper amount of fuel can be injected, NOx and SOx in the exhaust gas from a marine diesel engine can be reduced according to the present invention.
  • the oil pressure pump of the fuel injection valve open/close mechanism can be driven with a proper dynamic force due to the oil pressure pump of the fuel injection valve open/close mechanism being separated from the rotating shaft of the marine diesel engine, and returning of the working fluid from the relief valve back to the tank in order to release a surplus pressure as in the conventional fuel injection control devices can be prevented, and also compactification of fuel injection control devices can be achieved, according to the present invention.
