Definitions

• the present invention relates to a fuel injection amount control device for a V-type engine, and in particular, a pair of fuel injection amounts for each bank are provided on both sides of a cylinder opening of the V-type engine.
• the control device can maintain a predetermined rotation speed even when the engine tilts forward and backward. It has a link mechanism.
• a pair of fuel injection pump bodies mounted on both sides of a cylinder block of a V-shaped engine have a structure in which respective rack rods are in the same direction. It is mounted to perform the same function when it moves, and one of the fuel injection pumps has a governor and the other has a governor.
• the governor When the governor is not installed, the movement of the rack rod of the fuel injection pump to which the governor is attached is performed via the link mechanism. This is transmitted to the rack rod of the fuel injection pump. That is, as shown in FIG. 1, the link mechanism is widely used.
• a and a ' are both fuel injection pumps, and the fuel injection pump a' is mounted in the same direction as the fuel injection pump a. It has been done. That is, it is mounted so that when the respective rack rods c move in the same direction as each other, the same function is exerted.
• b is the injection pump governor, It is attached to the fuel injection pump a and adjusts the amount of fuel injection by moving the fuel and fuel injection pump a's rack rod c in response to changes in the engine load. are doing . Since the governor is not installed on the flue fuel injection pump a ', the movement of the rack rod c of the fuel injection pump a may be caused on either side of the joint shaft di.

• the transmission is transmitted to the rack rod c of the pump a ′.
• the rack rod c is moved in the direction of increasing fuel by the lever d 2.
• the engine is driven by its own weight, i-d, 2-2, causing the engine rotation speed to increase, while on the other hand, when the engine is tilting backwards, the engine will drop. ing .
• the present invention has been made in view of the above-described circumstances, and has the purpose of assembling the link mechanism from both sides of the connecting shaft as one element.
• the mounting direction of the pair of levers fixed to the shaft is changed so that they project in the same direction so that they project in opposite directions about the connecting shaft.
• the self-weight of the lever is offset so that the effect on the rack rod is not affected.
• the present invention provides an injection amount control device, and the left and right levers move in opposite directions by symmetrically mounting the levers in this manner. Fuel injection Even if the pump is mounted in the opposite direction, the injection amount can be controlled without any support, and the governor to be used should be a normal and cheap mass-produced product. I can do it.
• a single fuel injection pump having a governor on one side of a cylinder block and a governor on the other side are provided.
• a fuel injection control device for a V-type engine in which one fuel injection pump without a fuel injection pump is mounted, and a fuel injection pump with a governor
• the rack rod is automatically rotated in front of both the fuel injection pumps.
• the one connecting shaft provided and the connecting shafts are arranged so that the connecting shafts protrude in opposite directions with respect to the forces on both sides of the connecting shaft.
• a link mechanism consisting of a pair of linked links and forces, so that even if the engine tilts back and forth, both sides of the connecting shaft
• a fuel injection amount control device for V-shaped engine which is characterized by the fact that the rack rod moves under the weight of the fixed lever and that the lever does not move. It is done.
• the fuel injection pump provided with a governor increases the fuel injection amount when the rack rod projects, and when the rack rod contracts, the fuel injection amount is increased.
• the injection amount is controlled to be reduced, while the fuel without governor is controlled.
• the fuel injection pump is controlled so that the fuel injection amount is reduced when the rack rod protrudes, and the fuel injection amount is increased when the rack rod contracts. This is the feature.
• FIG. 1 ' is a schematic perspective view showing a conventional fling material injection amount control device for a V-shaped engine
• FIG. 2 is a schematic perspective view showing a specific example of a fuel injection amount control device for a V-shaped engine according to the present invention.
• FIG. 2 is a perspective view of one embodiment of the present invention.
• reference numerals 1 and 1 ' are both fuel injection pumps, one on each side of the cylinder block (not shown) of the V-engine. They are mounted facing each other. In other words, when the respective racks move in opposite directions, they perform the same function.
• the governor 2 is a governor.
• the governor 2 is an inexpensive mass-produced product, and is mounted on one of the fuel injection pumps 1 and corresponds to the engine load.
• Rack 1 rod 3 New paper Is moving to adjust the fuel injection amount.
• the connecting shaft 4 which is provided in a rotating position in front of the two pumps 1 and 1 ′, is provided.
• a pair of levers 4 2- ] and 4 2-2 which are fixed at both ends so as to protrude in opposite directions with the shaft as the center, and these Li down click that consists of a lever one and the fuel jetting port down-flops 1 Li down click 4 3 and the rack rod 3 of each of your good beauty 1 'you are connecting their respective
• the mechanism 4 is installed, the movement of the rack rod 3 of the fuel injection pump 1 with the governor mounted is controlled by the rack rod of the fuel injection pump 1 'without the governor mounted. 3 to control the fuel injection pump 1 '.
• the levers 4 2-i and 4 2-2 are fixed so as to protrude in opposite directions about the connecting shaft 4 i, so that their own weights cancel each other. It is done. And follow, et emissions is also di emissions is to tilt after tilted forward your good beauty bar one 4 2 - i, 4 2 - influenced 2 of Tsu by the own weight in the period movement of the rack rod 3 There is no problem. Thus, when the engine leans forward and backwards, the engine rotational speed does not change. As a result, the engine rotation speed does not fluctuate when the engine leans forward and backwards, even when using ordinary low-cost mass-produced governors. It has become possible to configure a fuel injection amount control device for a type of engine.
