Abstract
The utility model relates to a high efficient atomizing device for the carburettor of a gasoline engine. The high efficient atomizing device for the carburettor of a gasoline engine is composed of an oil inlet hole 1, a float assembly 2, a float chamber 3, a main oil metering hole 4, a spray pipe 5, etc. A fuel oil rotary flow guide body is arranged on the outlet position of the spray pipe 5. The type of the fuel oil rotary flow guide body can be an inner screw, or a spring, or a flow guide plate. Fuel oil which is sucked out from the spray pipe by the negative pressure of flow gas is sprayed towards a throat pipe in a rotary shape, the impact against probability of the fuel oil and air is increased, an atomizing degree is enhanced, the working performance of an engine is improved, fuel saving is achieved, and waste discharge and noise are lowered. Only part of the spray pipe is needed to be modified. The high efficient atomizing device for the carburettor of a gasoline engine has simple structure and marked atomizing effect. The actual measurement fuel saving of the high efficient atomizing device for the carburettor of a gasoline engine is more than 10%. The high efficient atomizing device for the carburettor of a gasoline engine is suitable for various gasoline engines.
Description
The utility model relates to petrol engine carburetor.
In order to reduce engine consumption, improve the engine operation performance, to reduce waste gas blowdown and noise, people have done very big effort, and have obtained certain effect.Aspect the atomization quality that improves Carburetor, did many trial especially, for example added air, and increased air mass flow and strengthen atomizing at the trunnion place of Carburetor; Or adopt variable venturi to control air mass flow, guarantee atomization quality; Or make the air rotational flow of trunnion, improve atomizing or the like, but because of the complicated dynamic property of oil, gas, emulsified liquid, and engine load needs often to change or not clear technical reason etc., make the achievement of above-mentioned atomizing measure, still rest on experimental stage or part operational phase.
Design objective of the present utility model is not change under the prerequisite of original Carburetor general structure, only set up additional structure at fuel-displaced jet pipe place, the fuel-displaced of jet pipe sprayed to trunnion with rotation status, when with trunnion in after the flow at high speed air fully mixes, form spray pattern efficiently, make the explosive combustion of fuel oil more abundant.
The utility model realizes that the major technique structure of above-mentioned design is: except that the conventional structure that contains petrol engine carburetor, characteristics are to be provided with fuel oil rotation deflector in the outlet port of fuel-displaced jet pipe.Above-mentioned fuel oil rotation deflector can be the water conservancy diversion internal spiral of outside nozzle, or in the nearly outlet port of jet pipe endoporus the spiral stream guidance spring is set.Above-mentioned fuel oil rotation deflector also can be at nozzle exit outer circumference or nearly outer rim place to be set the groove of some uniform equidirectional inclinations or the guide plate in hole are arranged.
The utility model is compared with conventional carburetor, has following positive effect:
1, the fuel oil of jet pipe ejection sprays to trunnion with rotation status, can be fully mixed with the high velocity air of trunnion, form atomization condition preferably, make drop thinner, enter in the firing chamber and can fully be burnt, improved combustion efficiency, improved service behaviour, reduce waste gas blowdown and noise, reached the fuel-economizing purpose.
2, do not change the Carburetor overall structure, only in outside nozzle fuel oil rotation deflector is set, simple in structure, easy for installation, atomizing effect is remarkable, goes for all kinds Carburetor, Carburetors such as routine automobile, motorcycle use.
3, through measured result over 2 years, the utility model is installed in fuel-economizing 24.4% on the CJ50 type trail bike; Be installed in fuel-economizing 18.5% on 125 motorcycles.
4, be installed in the utility model on the PZ11J Carburetor in August, 1991, and through Qingdao Carburetor factory engine bench test, after confirming high-efficiency atomizer is installed, power, torsion do not have influence during to each operating mode of motor; When engine speed per minute 2300 changeed, oil consumption descended 40%.
Below in conjunction with accompanying drawing in detail mode of execution is described in detail.
Fig. 1 is the conventional carburetor structural representation.
Fig. 2 is that jet pipe 5 outlet ports are provided with water conservancy diversion internal spiral schematic representation.
Fig. 3 is provided with spiral stream guidance spring schematic representation in jet pipe 5 endoporus.
Fig. 4 is that jet pipe 5 outlet ports are provided with the guide plate schematic representation.
Fig. 5 is the schematic top plan view of Fig. 4.
The petrol engine carburetor high-efficiency atomizer mainly is made up of oil inlet hole 1, float assembly 2, float chamber 3, main gauge hatch 4, jet pipe 5, trunnion 6, closure 7 etc., key is that jet pipe 5 outlet ports are provided with fuel oil rotation deflector, when high velocity air causes negative pressure at trunnion 6 places, outwards spray with rotation status from the fuel oil of 5 li sucking-offs of jet pipe, cause the fully mixed atomizing of fuel oil and air.Fig. 2-Fig. 4 is several structural types of fuel oil rotation deflector.
The nearly outlet port of jet pipe 5 endoporus is provided with spiral stream guidance spring 9, and makes spring 9 connect firmly (the routine riveting etc. of contracting in jet pipe 5 outlet parts) with the relative machinery of jet pipe 5 endoporus, and fuel oil is rotatable water conservancy diversion ejection.
