Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described, should be appreciated that embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Fig. 1 is the schematic representation of embodiment of the invention diesel engine fuel injecting amount control device.As shown in Figure 1, the invention provides a kind of diesel engine fuel injecting amount control device, comprise housing 1, cover plate 2, fuel-flow control piece 3, adjusting screw 4, return spring 5, control pull rod 6, buoyant beam 8, fuel-flow control pull bar 9, cover plate 2 lids are loaded on the top of housing 1.
First through hole 11 is set on the housing 1, and adjusting screw 4 is arranged in first through hole 11, is connected to the upper end portion of fuel-flow control piece 3.Second through hole 12, third through-hole 13 are set on the housing, and control pull rod 6 is arranged in second through hole 12, third through-hole 13, is spirally connected with the middle part of fuel-flow control piece 3; During control pull rod 6 move left and right, fuel-flow control piece 3 is followed control pull rod 6 and is moved together.First spring block 14 is set on the control pull rod 6, and control pull rod 6 is arranged in return spring 5, and return spring 5 one ends are connected to and link stopper 14, the other end butt with in housing 1.Buoyant beam 8 butts of the underpart of control pull rod and speed regulator 7.
The adjusting screw 4 and first through hole 11 have suitable screw thread, adjusting screw 4 mobilizable wearing and first through hole 11.Reduce what of oil mass, can regulate by adjusting screw 4.
The present invention is installed on the diesel engine speed regulator 7, need reduce the busy hour of output when diesel engine, by pulling control pull rod 6 past moving right, fuel-flow control piece 3 is followed toward moving right, force the fuel-flow control pull bar 9 of the buoyant beam 8 pulling diesel engines in the diesel engine speed regulator to move simultaneously toward the direction that reduces fuel injection quantity, thereby reach the minimizing fuel injection quantity, save the purpose of fuel consume.When diesel engine when high load working condition moves, then unclamp control pull rod 6, fuel-flow control piece 3 is got back to the home position under the effect of return spring 5, fuel-flow control piece 3 does not contact with buoyant beam 8 in the device speed regulator, diesel engine is by the state operation that does not reduce fuel injection quantity, in addition, reduce how much can regulating of fuel injection quantity by adjusting screw 4.
