[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifugal governor for a diesel engine, and more particularly to a technique for controlling a fuel injection amount during engine overload operation to be constant.

[0002]

2. Description of the Related Art As a centrifugal governor for a diesel engine, for example, the one shown in FIG. 5 has been conventionally known. Here, FIG. 5 is a front view of a centrifugal governor according to a conventional example, and FIG.
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
It is configured to receive it. Note that the swing regulation pin 116 is connected to the fuel regulator 117 at the position corresponding to the full load (4/4).
Functioning as

[0005] As shown in FIG. 6, the torque-up device 118 includes a case body 119 and a receiving portion 120 of the second lever 104 which protrudes from the front end side of the case body 119 so as to be able to advance and retreat.
6 and a torque spring 122 (see FIG. 6) housed in the case body 119 to resiliently urge the torque pin 121. The engine shown in FIG. When a transition is made from the load operation state to the overload operation state shown in FIG. 7, the torque pin 121 is projected as shown in FIG.
The lever 103 is swung to the fuel increasing side R to increase the fuel injection amount and exhibit tenacity. In FIG. 5, reference numeral 123 denotes a governor case, and reference numeral 124 denotes a governor shaft for rotating the governor weight 107.

[0006]

The above prior art has the following problems. If the engine is operated for a long period of time, wear occurs on 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 wear occurs, as shown in FIG. 8, during an overload operation in which the torque pin 121 projects, fuel is injected in excess of the original injection amount at the time of torque increase. FIG. 8 shows a state in which the torque pin 121 protrudes to the maximum.
In such a case, although slightly, the operation continues beyond the maximum torque-up fuel injection amount Tu. The increase in the fuel injection amount during such overload operation is caused not only by the maximum torque-up fuel injection amount Tu, but also by the maximum torque-up torque operation (Tu) from the full load operation (4/4).
This occurs in the entire torque-up operation region up to.

[0007] The increase in the fuel injection amount during overload operation due to wear is caused by the above-mentioned swing regulating pin 116 and the swing contact portion 1.
In addition to the wear of the rack pins 15, the wear also occurs due to the wear of the rack pins 112. FIG. 9A shows the position of the rack pin in an initial state where it is not worn, and FIG.
FIG. 6 is a diagram illustrating the position of a rack pin in a case where is worn or the output portion of the first lever 103 is worn.

[0008] As shown in FIGS.
Of the rack pin 1 by the output portion 108 of the
12, the holding member 129 is constantly pulled by the start spring 109, and as shown in FIG.
Since it is pressed against the contact surface 131 of the lever output portion 108, when abrasion occurs, the center position of the rack pin 112 is shifted toward the increasing side by the amount of abrasion d. Therefore, when the operation should be performed at the full load equivalent position (4/4), the operation is performed at a position shifted to the increasing side. This similarly occurs in the torque-up operation region, and the fuel injection amount increases.

Further, as shown by e in FIG. 6, the input section 10 of the first lever 103 to which the governor force G inputs.
6 and the governor sleeve 125 (see FIG. 5)
Even if the contact surface 134 is worn, the position of the rack pin 112 will shift to the increasing side. Thus, the contact surface 12 of the fuel restrictor 117 at the full load equivalent position (4/4)
6.127 wear, abutment surface 130 for metering device 111
Since the wear of 131 and the wear of the contact surfaces 132 and 134 of the first lever 103 with respect to the input portion 106 act in the fuel increasing direction, the operation of the engine in the torque-up operation region in such a state. If continued, more fuel will be injected than the preset injection amount, and there is a problem that harmful substances in the exhaust gas will increase.

[0010] To solve this problem, if the length of the torque pin 121 is shortened in anticipation of the wear in advance, the inconvenience of increasing the fuel injection amount even when the above wear occurs can be solved. However, according to this solution, an injection amount smaller than the originally required injection amount is set in the initial period of engine operation when wear does not occur, and there is a problem that engine stall easily occurs in an overload operation state. .

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 that can suppress operation with an increased amount of fuel due to abrasion of the mechanism of the centrifugal governor in an overload operation state by a simple and inexpensive method. I do. 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.
