Abstract
The utility model relates to an oil economizer for a single-cylinder diesel engine. The oil economizer for a single-cylinder replacing a regulation screw is arranged on the cover of the timing gear chamber of the diesel engine. Thus, a shift fork for speed regulation can be deviated; the stability of oil injection can be enhanced. The utility model is provided with a sleeve body. A pull pin is arranged in the sleeve body. One end of the pull pin is provided with a top core. The other end of the pull pin is sheathed with a screw sleeve. A slotis arranged at the outer end of the screw sleeve. A pull ring is penetrated at the end of the pull pin which is corresponding to the slot. A spring is sheathed on the pull pin in the sleeve body. A tight nut is assembled on the sleeve body. If the oil economizer is assembled on the single-cylinder diesel engine, fuel oil saving can reach 6.7-7.8%. In addition, the reserve torque of the diesel engine can be increased.
Description
The utility model relates to the device of saving fuel of internal combustion engine, especially the gasoline-saving device of single cylinder diesel.
Single cylinder diesel is used comparatively extensive in China, be used for hand tractor, small farm vehicle, equipment of small motor ship and pumping equipment of farming and transportation or the like as the rural area, all useful this diesel engine device that is used as power.In order to guarantee that diesel engine has certain reserve torque and reduces the fuel oil waste as far as possible, cover at the housing for timing gear of this diesel engine an adjusting screw is housed, distance when being used for setting up diesel engine static state between speed governing shift fork and this adjusting screw top, the peak excursion distance of qualification speed governing shift fork.The problem that present this structure exists is, when diesel engine turns round, the speed governing shift fork takes place to swing back and forth at a high speed and is offset apart from bias internal one distance back at above-mentioned peak excursion and surpasses specified fuel feeding relevant position, the plunger pump fuel injection quantity can not be stabilized on the actual load desired level, part fuel oil becomes unnecessary supply and wastes, especially when the big load operation running of diesel engine easily too much fuel consumption make the insufficient and over-emitting black exhaust of oil inflame; In addition, because the qualification of speed governing shift fork peak excursion distance, the reserve torque of diesel engine can not fully improve.
The purpose of this utility model is the device that a kind of substitute adjustment screw is provided under the situation that does not change the single cylinder diesel structure, and this device is promptly inscribed and stated the single cylinder diesel gasoline-saving device.This device can allow the speed governing shift fork be offset with the diesel engine running and increase offset distance with diesel engine speed, can eliminate the speed governing shift fork again and tremble back and forth, stablizes oil spout speed, saves fuel consume, increases the reserve torque of diesel engine simultaneously.
In order to achieve the above object, the utility model adopts the body of a band internal and external threads, be equipped with in the cover body cavity and draw pin, draw and be with spring on the pin, the swivel nut that is used for Regulation spring elastic force passes and draws pin one end to twist internal thread in body by its outside thread, draws the pin the other end to be provided with plunger tip, and it is external that this plunger tip partly stretches out cover, the swivel nut outer end is provided with opening slot, has a through hole in the pin end of drawing of swivel nut opening slot corresponding part.
Different thrusts according to speed governing shift fork offset distance size is produced are equipped with inner spring and outer spring drawing of above-mentioned single cylinder diesel gasoline-saving device on the pin; In the through hole that draws the pin end, be coated with Yi Laquan.
The utility model single cylinder diesel gasoline-saving device replaces former adjusting screw to be installed in housing for timing gear covering, the plunger tip of this gasoline-saving device leans the speed governing shift fork all the time can allow the speed governing shift fork be offset with the diesel engine running again, and the ultimate range of comparing this skew with existing device increases, so both having eliminated the speed governing shift fork trembles when diesel engine turns round back and forth, improve the stability of oil spout, save fuel consume, increased the reserve torque of diesel engine again, and help the starting of diesel engine, through test determination, this gasoline-saving device of single cylinder diesel fit on can be saved fuel oil 6.7-7.8%, black smoke discharge amount when having reduced the diesel engine high-load operation simultaneously helps environmental hygiene.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1: single cylinder diesel gasoline-saving device sectional view;
Fig. 2: draw pin;
Fig. 3: body;
Fig. 4: swivel nut;
Fig. 5: plunger tip.
See Fig. 1, this single cylinder diesel gasoline-saving device has the body 7 of a band internal and external threads, be equipped with in body 7 chambeies and draw pin 3, draw and be with inner spring 4 and outer spring 6 on the pin 3, the swivel nut 2 that is used for Regulation spring elastic force passes and draws pin 3 one ends to twist in the internal thread of body 7 by its outside thread, draw pin 3 the other ends to be provided with plunger tip 8, plunger tip 8 parts are stretched out outside the body 7, swivel nut 2 outer ends are provided with opening slot, pin 3 ends of drawing in this opening slot corresponding part have a through hole, be coated with in this through hole and draw circle 1, be fitted with fastening screw nut 5 on the body 7.
Above-mentioned single cylinder diesel gasoline-saving device, draw a pin 3 and a core 8 can disjunctor also can split, be good with split.
This gasoline-saving device replacement adjusting screw is loaded on the single cylinder diesel housing for timing gear and covers, make plunger tip 8 lean the static speed governing shift fork of diesel engine, swivel nut 2 position regulation back well are positioned body 7 inwalls with Cock screw, speed governing shift fork pushing plunger tip 8 during the diesel engine running, plunger tip 8 overcome inner spring 4 tension force and in contract, rotate an angle with the skew injection pump plunger mandrel of speed governing shift fork; When diesel engine speed increases, under the flyball centrifugal action, the speed governing shift fork continues pushing plunger tip 8, plunger tip 8 overcome the tension force of inner spring 4 so that overcome outer spring 6 tension force and in contract, make the injection pump plunger mandrel rotate more wide-angle, the corresponding raising of unit time fuel injection quantity.Before the diesel engine starting, will draw circle 1 outer draw to exceed swivel nut 2 apical positions and twist turn 90 degrees, plunger tip 8 loses the pushing force that spring pressure eliminated the speed governing shift fork is started diesel engine; After this will draw circle 1 to twist to turn 90 degrees and fall within the groove, plunger tip 8 leans the speed governing shift fork again.
