Abstract

The invention discloses a breeze type motorcycle (vehicle using motor) carburetors, are still plunger-type structure.Upper body is provided with oil inlet passage idling slot and main oil groove.Main oil groove is to connect the lifting of air throttle by main spindle to control the size of throttle, idling slot air throttle is motionless be not added with throttle in the case of to provide the idling of engine stabilizer.Carburetor is oil storage seat, and the thick-and-thin height of pasta is controlled by the setting of float-controlled valve.The distinctive feature of the present invention, exactly engine combustion is instructed to put into practice with traditional yin-yang theory, carburetor oil inlet intake method is improved with the method for the traditional Chinese medical science " qi-regulating ", for original carburetor there are the drawbacks of, it is deep to drop main oil groove and idling slot fuel head (wherein idling slot has dropped four millimeters, and main oil groove has dropped six millimeters).In this way, it is possible to reduce air contact surfaces make the oil inlet quantity of carburetor and air inflow reach the more rational combustion state of saturation in cylinder, and so as to make, engine overall performance includes energy saving and service life is obtained for very big promotion.

Description

Breeze type small-displacement motorcycle carburetor

Technical field：The present invention relates to a kind of small-displacement motorcycle carburetors, are especially suitable for small mini, creek horse, Xinchen, Europe The engines such as Xiang use.

Background technology：Existing small-displacement motorcycle does not achieve the effect that fuel-efficient when discharge capacity is small.For example I just uses The small mini vehicle using motor of a clever fox money, carburetor fuel consumption per hundred kilometers before not improving is up to 2.5 liters or more or even rubs than 125 types Support also excessive fuel consumption.This is also that this vehicle seems small and exquisite, is particularly suitable for working clan and uses, and extremely low important of practical popularity rate Reason.

There are one drawbacks for small-displacement motorcycle, and practical generally to ride to after tens kilometers, upward slope power clearly declines, Easily there is fatigue state in engine.

Invention content：The two above drawbacks, two aspects of actually one problem, the exactly present invention to be solved The problem of.How to solveThe present invention be out of engine combustion law finding method, it is therefore necessary to illustrate that lower invention is thought Road.

The working condition of engine is substantially what carburetor determined.Carburetor is the oil supply system of engine, like people The heart of body, if mechanism of qi is excessive or too small, blood conveying it is too fast or excessively slow, can all influence the running of entire viable organism.

How the carburetor that with engine matches is made, it is important to exquisite and hold the gentle balance of oil.I Inventing total thinking is：The fuel head of deep drop idling slot and main oil groove reduces air contact surfaces, can control oil gentle in this way Into cylinder amount, slow down burning velocity so that the gentle combustion state for reaching relative saturation in cylinder of oil, so as to reach the mesh of fuel-economizing 's.

The present invention specific improvement project be：

1st, plunger type carburetor is divided into the top part and the bottom part point, and lower part is oil storage seat also known as float chamber.Upper body has a indent Slot can form certain air pressure, make oil not excessive.This original-pack carburetor upper casing inner groovy is ten millimeters, improved indent Groove height is seven millimeters.

2nd, original carburetor, idling slot overall length are 26 millimeters, and one millimeter is increased after improvement, are 27 millimeters. Original main oil groove of carburetor is 27 millimeters (containing nozzle, this carburetor, nozzle and main oil groove are connected as a single entity), is improved Length is 30 millimeters afterwards.

3rd, original carburetor idling slot metering-orifice is three groups, is four groups after improvement, aperture is constant.

4th, the main spindle of original carburetor is changed to 110 motorcycle carburetor spindle of camber beam.

5th, original carburetor oil storage seat increases six millimeters after improving.

Description of the drawings：

The present invention is further illustrated below in conjunction with the accompanying drawings.(this figure is drawn for 1: 2 ratio)

Fig. 1 is schematic diagram of the present invention

Fig. 2 is idling slot of the present invention

Fig. 3 is main oil groove

Fig. 4 is main spindle

Fig. 5 is oil storage seat

1 is upper body indent flute length in figure；2 be idling slot length；3 be main oil groove length, and A, B, C, D are respectively idling slot amount Hole；E, F, G, H are main oil groove metering-orifice.

Specific embodiment

Breeze type small-displacement motorcycle carburetor, basic structure do not change, and only each element size has larger Improvement.First, compared with former carburetor, three millimeters are 1. shortened in the inner groovy Fig. 1 of upper body, it means that carburetor idling slot Three millimeters of fuel heads of Fig. 2 and main oil groove Fig. 3 entire lowerings.Secondly, idling slot Fig. 2 increases one millimeter, i.e. idling slot again Totally have dropped four millimeters of pastas；Again, main oil groove oil Fig. 3 increases three millimeters namely main oil groove Fig. 3 and has totally sunk six again Millimeter pasta.Carburetor is the high thing of precision in itself, and critical component differs a few tenths of a mm, has in performance larger Change.Due to greatly reducing air contact surfaces, original combustion system is changed, so as to be saved greatly the energy, is extended The working life of engine.

A, B, C, D idling slot metering-orifice are preferably preferably big in upper end, aperture in Fig. 2, a pair of of metering-orifice are increased after improvement, it is therefore an objective to increase Greater than tolerance, then, to increase idling slot Fig. 2 air inflows whyBecause cylinder oil inlet be mainly from idling slot into, it is main Oil groove Fig. 3 has been a kind of booster action.This point is very profound, it is considered that, main oil groove Fig. 3 is to drive main oil by lifting throttle Needle Fig. 4 controls motorcycle speed, seems the main thoroughfare of power fuel feeding, idling slot Fig. 2 is only to provide stable idling. Actually this is not so, and the effect for carrying throttle further increases the oil inlet quantity of idling slot Fig. 2, and main oil groove Fig. 3 has been a kind of adjustment effect, no It is the main thoroughfare of fuel oil needed for cylinder, but it is to realize that idling slot Fig. 3 provides the basic of very strong driving force.So main oil groove metering-orifice In Fig. 3 E, F, G, H preferably open it is small and under, although main oil groove Fig. 3 increases three millimeters, its metering-orifice quantity is constant, and aperture is constant, It is only equidistant to have moved down three millimeters.Persistently surge power could be generated in this way.

Since breeze type carburetor totality cylinder oil inlet air inflow substantially reduces, and main oil groove Fig. 3 increases length, institute Should correspondingly lengthen main spindle Fig. 4, the present invention is matching with camber beam 110CC carburetor needle valves.
