FIG. 7 is a schematic diagram of the centrifugal governor showing a full load operation state, and FIG. 7 is a schematic diagram of the centrifugal governor showing an overload operation state.

As shown in FIGS. 5 to 7, this centrifugal governor 101 comprises a governor lever 105 composed of a first lever 103 and a second lever 104 pivotally supported by a pivot shaft 102, respectively. A governor weight 107 is operatively connected to an input portion 106 of the first lever 103, and a start spring 109 and a rack pin 112 which is a metering tool 111 of a fuel injection pump 110 are connected to an output portion 108.
The speed control lever 114 is connected to the second lever 104 via a governor spring 113, and the start pin 109 and the governor spring 113 press the rack pin 112 toward the fuel increasing side R. The rack pin 112 is pressed to the fuel reduction side L via the first lever 103 by the governor force G of the weight 107.

The governor lever 1 is driven by an unbalanced force between the elastic pressure on the fuel increasing side R and the pressing force on the fuel decreasing side L.
The rack pins 112 are moved by metering by swinging the 05. Further, the swing contact portion 1 of the second lever 104
15 at full load equivalent position (4/4) with swing regulation pin 116

[0006]

The above prior art has the following problems. If the engine is operated for a long time, the contact surface 126 of the swing contact portion 115 and the contact surface 127 of the swing regulating pin 116 shown in FIG. When such abrasion occurs, as shown in FIG. 8, the position of the second lever 104 is operated to increase the amount as compared to before the abrasion, and the first lever 104 received by the receiving portion 120 of the second lever 104 is operated. The position of the lever 103 is also operated on the increasing side, and as a result, the rack pin 112 is also located on the increasing side from the full load equivalent position (4/4).

The increase in fuel injection amount due to wear is caused by
Not only the wear of the swing regulating pin 116 and the swing contact portion 115 but also the wear of the rack pin 112 is caused. FIG.
9A is a diagram showing a rack pin position in an initial state where the rack pin is not worn, and FIG. 9B is a diagram showing a rack pin position when the rack pin 112 is worn or the output portion 108 of the first lever 103 is worn. is there.

As shown in FIGS. 5 and 9, the rack pin 112 is held between the output portion 108 of the first lever 103 and the holding member 129, and the holding member 129 is constantly pulled by the start spring 109.
As shown in FIG.
Is constantly pressed against the contact surface 131 of the first lever output unit 108, so that when the abrasion occurs, the center position of the rack pin 112 shifts toward the increasing side by the amount of abrasion d. Therefore, even when the operation is performed at the full load equivalent position (4/4), the operation is performed at a position shifted toward the increasing amount side.

Further, as shown by e in FIG. 6, the input portion 1 of the first lever 103 to which the governor force G inputs.
Even if the abutment surface 132 of 06 and the abutment surface 134 of the governor sleeve 125 (see FIG. 5) are worn, the position of the rack pin 112 will shift to the increasing side. As described above, the wear of the contact surfaces 126 and 127 of the fuel restrictor 117 at the full load equivalent position (4/4) and the contact surface 1 of the metering device 111
30, 131 wear, input portion 106 of first lever 103
Since the contact surfaces 132 and 134 are worn in the fuel increasing direction, if the engine operation is continued in such a state, more fuel is injected than the preset injection amount. As a result, there is a problem that harmful substances in the exhaust gas increase.

[0010] To solve this problem, if the position corresponding to the full load (4/4) is set in advance in anticipation of the amount of wear, the above-mentioned inconvenience can be solved even when the wear occurs. The fuel injection amount is set lower than usual in an initial state where this does not occur, and there is a problem that the engine output decreases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a centrifugal governor for a diesel engine which can solve the above problems. An example of a specific purpose is as follows. (a) Provided is a centrifugal governor for a diesel engine, which can suppress the operation of the centrifugal governor in a state in which the amount of fuel is increased due to wear of the mechanism of the centrifugal governor by a simple and inexpensive method. It should be noted that the problems of the invention other than those described above and the means for solving the problems will be described in detail in the description in the following specification.

(7) The governor (G) is biased to push the metering device (11) to the fuel decreasing side (L) via the input portion (6) of the first lever (3), and the fuel increasing side (R) is pressed. ), And the governor lever (5) is swung by a disproportionate force between the elastic pressure on the fuel reduction side (L) and the pressing force on the fuel reduction side (L) to move the metering tool (11). 17) is configured to receive and regulate the swing contact portion (15) of the second lever (4) in the full load operation state, and the first lever (3) and the second lever (4) A torque increasing device (18) is interposed between the two levers to increase the fuel injection quantity in conjunction with the transition from the full load operation state to the overload operation state, and to increase the torque to the second lever (4). The tip (3) of the device (18)
4) A receiving portion (20) for receiving the fuel is provided, and the fuel regulating device (1) is provided.
When the second lever (4) is received in (7), the tip (34) of the torque-up device (18) is received by the receiving portion (20), so that the output portion (8) of the first lever (3). The position of the metering tool (11) operated according to the position corresponding to the full load (4/4)
In a centrifugal governor of a diesel engine set so as to be as follows, a metering tool caused by wear of at least one of a biasing member (42) of governor force (G) and an input portion (6) of a first lever (3). (11)
The tip (34) of the torque increasing device (18) and the receiving portion of the second lever (4) so as to reduce the amount of movement of the second lever (4) to the fuel increasing side.
A centrifugal governor for a diesel engine, characterized in that at least one of (20) is provided with a wear adjusting part (38).
