With reference to Fig. 6, single cylinder diesel speed-regulating system, is the distributive value by controlling diesel pump, to meet in the prior art
Use demand of the diesel engine under different operating condition revolving speeds, speed-regulating system is mainly by flying block part 5, lever shaft 6, speed governing tension spring 7, adjusting
The components such as fast handle 8, governor lever 9, oil mass push rod 13, control lever 10, acceleration cable 11, speed regulation axis 12 are constituted.Its work
Mode is: when needing diesel engine speed to increase, opening the throttle, acceleration cable 11 is drawn by control lever 10, speed adjusting lever 8
Dynamic speed governing tension spring 7, governor lever 9 rotates counterclockwise under the pulling force effect of speed governing tension spring 7 around lever shaft 6, before governor lever 9
The speed regulation shift fork 91 at end stirs the oil mass push rod 13 on diesel pump, to adjust the fuel delivery for increasing diesel pump, meanwhile, fly block part
5 automatically open under the action of crankshaft accelerated service centrifugal force, and the speed regulation axis 12 positioned at winged 5 center of block part pushes out
It moving, the speed regulation axis 12 elapsed outward is close and supports the balance end 92 of governor lever 9, to limit the rotation of governor lever 9, until
The pulling force generated with speed governing tension spring 7 reaches balance, and diesel engine is made to operate stabilization of speed；When needing diesel engine speed to reduce, pine
Acceleration cable 11 is opened, speed regulation shift fork 91 reversely stirs oil mass push rod 13, reduces diesel oil fuel delivery to realize the purpose for reducing revolving speed.
But: when acceleration cable 11 is totally released, 7 elastic recoil of speed governing tension spring drives speed regulation shift fork 91 reversely to stir on diesel pump
Oil mass push rod 13 be directly repositioned to closed state, make diesel pump fuel cut-off；At this point, diesel engine can not be transported in the idling state
Row, instantaneous auto extinguishing.Therefore, it needs to reduce revolving speed in single cylinder diesel, i.e., is idle mistake from high-speed cruising reduction of speed
Cheng Zhong, needs manual hand manipulation, and control acceleration cable prevents the direct return of oil mass push rod 13 from closing, can just make diesel engine reduction of speed
To idling mode and keep running in the idling state.
The single cylinder diesel of above-described embodiment 1-3, Idling Process for Diesel Engine regulating device be mounted on diesel engine gear chamber side or
Person's gear chamber side cover plate outer end face, it is compact-sized, the layout of single cylinder diesel complete machine, the idle adjusting device and bavin are not influenced
The original speed-regulating system of oil machine is mutually linked, and the collective effect in diesel engine reduction of speed makes diesel oil function with idling mode stable operation.
Its working principle is that: for single cylinder diesel in acceleration mode, acceleration cable 11 pulls control lever 10 to pass through idle speed control arm 1 simultaneously
Drive idle speed adjustment bar 2 mobile to the rear extreme direction for being equipped with idle speed limit component 3, single cylinder diesel original speed adjusting gear is independent at this time
Effect, the accessible movement with the displacement of idle speed control arm 1 of Idling Process for Diesel Engine regulating device do not have diesel engine accelerating ability
It influences；Diesel engine from run at high speed reduction of speed be idle state during, pass through speed adjusting lever 8, idle speed control arm 1 pull
Idle speed adjustment bar 2 is mobile to the preceding extreme direction of idle speed adjustment bar 2, at this time since the elastic force of idle speed limit spring 32 acts on, limitation
The distance that extreme direction moves forward of idle speed adjustment bar 2, draw the speed governing tension spring 7 of single cylinder diesel speed-regulating system will not because of throttle
Line 11 is totally released and perfect elasticity return, and oil mass push rod 13 will not completely close, so that diesel pump can be with idling institute
The fuel delivery needed keeps Idling Process for Diesel Engine operating.
In addition, idle speed limit spring 32 can be adjusted by adjusting position of the speed regulation nut 33 on idle speed adjustment bar 2
Restraining position, to achieve the purpose that adjustment and control Idling Process for Diesel Engine revolving speed size.
Above-described embodiment 1-3 common beneficial effect is: single cylinder diesel is equipped with Idling Process for Diesel Engine regulating device, passes through
The position-limiting action of its idle speed limit component 3 limits the mobile distance of extreme direction forward of idle speed adjustment bar 2, further limits control
The rotational angle of lever 10, when so that acceleration cable 11 being in the state being totally released, oil mass push rod 13 is because of idle speed limit spring
32 effect can not be returned to closed state.Oil mass push rod 13 is totally released because of acceleration cable 11 when solving diesel engine reduction of speed
And the problem of directly closing, being able to maintain diesel pump with fuel delivery needed for idling continues fuel feeding, makes diesel engine in idling mode
Lower stable operation；It solves the problems, such as to lead to diesel engine auto extinguishing because of diesel pump fuel cut-off；Solve single cylinder diesel from
During high-speed cruising reduction of speed is idle, manual hand manipulation is needed just diesel engine speed to be made to be down to idling mode simultaneously
Keep idle problem.
Further beneficial effect is the angle of rotation that the Idling Process for Diesel Engine regulating device passes through restriction control lever 10
Degree, because of the effect of idle speed limit spring 32, prevents oil mass push rod 13 from being returned to and completely closes when acceleration cable 11 is totally released
State.Solve since diesel pump oil mass push rod 13 is in close state when single cylinder diesel starts again, can not fuel feeding to
Can not across-the-line starting diesel engine the problem of.
Further beneficial effect is, by adjusting position of the speed regulation nut 33 on idle speed adjustment bar, to change idling
32 restraining position of limit spring, can be realized and be more accurately controlled to Idling Process for Diesel Engine revolving speed.
Further, the utility model single cylinder diesel installs Idling Process for Diesel Engine regulating device, it is not limited to bavin
Oil machine demarcates the adjusting of idling, can also be carried out by adjusting speed regulation nut 33 to diesel engine speed according to user's use demands
It adjusts, and is able to achieve diesel engine stable operation under the setting speed.
It should be pointed out that above-described embodiment is only the technical concept for illustrating the utility model, the ordinary skill of the art
