い。 However, when starting the internal combustion engine, a fuel injection amount that is approximately 1.5 to 2 times the fuel injection amount limited by the above is required, but the action of the above stopper ensures that the internal combustion engine has satisfactory starting performance. Therefore, various proposals have been made to solve this problem. For example, Jikosho 51
There is a start-up increasing device as in No. 12594, which is integrated with the fuel injection pump, but these devices are operated manually or hydraulically, but cannot be directly applied to internal combustion engines for outboard motors.

対方向に移動させるようになつている。 In this governor device 22, a governor drive pulley 20 is fixed to a governor drive shaft 26 which is rotatably supported by a bearing 25 on the side of the governor body 24, and a governor housing provided at the lower part of the governor drive shaft 26. A plurality of governor weights 27 are provided within the 28, and are arranged so that the centrifugal force of the governor weights 27 and the spring force of the governor spring 29 are approximately balanced, increasing the rotational speed of the engine and increasing the governor weights. When the centrifugal force of 27 exceeds the spring force of the governor spring 29, the governor spindle 30 is rotatably supported via a floating lever pin 33 by a regulator lever 32 supported by a regulator lever shaft 31. This causes the floating lever 34 to be pressed, and the fuel injection amount adjustment valve of the unit injector 9 shown in FIG. A fuel injection amount increasing/decreasing mechanism (hereinafter referred to as a control rod) 36, which rotates the lever 15, is moved in a direction opposite to the fuel increasing direction E.

外部から矢印Ｆの方向に引くようにしている。 Next, when the diesel engine 2 is started, if the stopper lever 37 is in the position indicated by the two-dot chain line in FIG. 5, the fuel injection amount will be limited and the injection amount necessary for starting will not be obtained. When the engine is started, the clutch of the outboard motor is disengaged, so the stopper lever 37 is rotated to the position shown by the solid line in FIG. A lever 41 is fixed to 38, and this lever 41 is pulled in the direction of arrow F from the outside.

The lever 41 and a clutch (not shown) are connected by a link or the like so that the lever 41 and the clutch 2 limit the amount of fuel injected to the control rod 36.
The lever 41 is pulled in the direction of arrow F, and the action of the stopper lever 37 is released.

ての機能をはたすようになる。 That is, if the starting fuel increase device of the present invention is applied to an internal combustion engine for an outboard motor, since the clutch is disengaged when the engine is started, the stopper 37 is automatically released as shown by the solid line in Fig. 5, and the unit indicator is released. Since the amount of fuel injected from Ekta 9 is increased from 1.5 to twice the amount injected in the restricted state, it is easy to operate and can be started, and the clutch engages when entering a normal operating state with a load. Figure 5 2
The stopper 37 comes to function as a stopper as shown by the dotted chain line.
従つて、本発明の始動時燃料増量装置を適用し

More injections can be made. Furthermore, the present invention allows for both stop and limit functions with a single lever.
