Abstract

The utility model provides a gas suction speed-limiting mechanism which is arranged between a manifold connected with a carburetor and a reed valve connected with a crank axle chamber, and the gas suction speed-limiting mechanism is obconical; the upper end of the gas suction speed-limiting mechanism is slightly smaller than an upper opening of a mouth of the manifold and gradually retracts to the inside from the upper opening to the lower side, so that a lower opening of the manifold at the lower end is far smaller than the upper opening; however, the obconical body part and the lower opening of the gas suction speed-limiting mechanism are arranged in the reed valve. Therefore, gas inlet runner can be reduced and oil gas flow can be stabilized in a centralized way so as to achieve the effect of limiting vehicle speed.

Description

The air inlet speed limiting mechanism

Technical field

The utility model relates to a kind of structure design that limits the oil gas charge flow rate, relates in particular to a kind of air inlet runner that dwindles, and concentrated stabilized hydrocarbon flow, reaches the air inlet speed limiting mechanism of limiting vehicle speed.

Background technique

At present external automobile, motorcycle all are in engine without speed limit, to install speed limiting device additional; Make the vehicle-speed limit of car scooter rules; And its speed limiting device can be divided into two kinds of mechanical type and electronic types haply; Wherein, this mechanical type can reduce engine horsepower and change transmission (speed change reduction speed ratio) deceleration to reach the speed limit effect by changing engine air admittance, vent systems, compression ratio; And electronic type is utilize to postpone the engine ignition angle, misfires when making the high rotating speed of engine or postpones, and reaches the speed limit effect.

Yet, in the face of adding of international vehicle environmental protection rules tight, for example as the MOPEAD of European Union, MOFA etc., the pollution rules of implementing in 2002, the condition of its content institute standard is more harsh, is not that common speed limiting device just can reach and has environmental regulation and cornering ability concurrently; In addition, general speed limiting device causes intake trubulence easily, forms the state that air inlet has some setbacks, and makes the driver when quickening, can produce the sensation of irregularity.

Summary of the invention

Because each item shortcoming of above-mentioned existing speed limiting device, the inventor exhausts the concentrated research of its intelligence then and overcomes, and is engaged in accumulating experience of this industry with it; And then develop a kind of air inlet speed limiting mechanism; Can dwindle air inlet runner, and concentrated stabilized hydrocarbon flow, reach the effect of limiting vehicle speed.

So the main purpose of the utility model promptly at a kind of air inlet speed limiting mechanism of design, can be dwindled air inlet runner, and concentrated stabilized hydrocarbon flow, reach the effect of limiting vehicle speed.

For reaching above-mentioned purpose, the utility model is achieved in that a kind of air inlet speed limiting mechanism, and it is arranged on the manifold that is connected with Carburetor; And one with leaf valve that crankshaft room is connected between, wherein, this air inlet speed limiting mechanism slightly is an inverted cone shape; Its upper end tool is slightly less than the upper shed of the mouth of pipe of manifold; And contract in gradually downwards by upper shed, the under shed that makes its lower end is much smaller than upper shed, and its taper body portion and under shed then place in the leaf valve; Whereby, can dwindle air inlet runner, and concentrated stabilized hydrocarbon flow, reach the effect of limiting vehicle speed.

Embodiment

For making your auditor understand purpose, characteristic and the effect of the utility model, existing by following concrete embodiment, and cooperate appended graphicly, the utility model is done one specifies as follows:

See also Fig. 1, Fig. 2 and Fig. 3, be respectively stereogram, the side view of the utility model, and embodiment figure.As shown in the figure:

This air inlet speed limiting mechanism 1; It is arranged on the manifold 2 that is connected with Carburetor (not looking among the figure), and one with leaf valve 3 that crankshaft room's (not looking among the figure) is connected between, wherein: this air inlet speed limiting mechanism 1 slightly is an inverted cone shape; Its upper end tool is slightly less than the upper shed of the mouth of pipe of manifold 2; And contract in gradually downwards by upper shed, the under shed that makes its lower end is much smaller than upper shed, and its taper body portion and under shed then place in the leaf valve 3.

Through the structure design of the utility model, by the mixed oil and gas of Carburetor air and gasoline, more just must be behind manifold 2 through air inlet speed limiting mechanism 1; And its by greatly by diminishing air inlet runner, can effectively control oil gas and get into the amount in the leaf valve 3, and because of its special conical design; Make that the oil gas of low speed air inlet runner is mobile smooth and easy, effectively the Control Engine rotating speed not only can make acceleration more smooth and easy in legal Maximum speed limit value; And have fuel-efficient again and the reduction exhaust pollution, whereby, utilize and dwindle air inlet runner; And concentrated stabilized hydrocarbon flow, reach the effect of limiting vehicle speed.

Brought forward is said, the existing speed limiting device innovation of the design of the utility model, and tool practical with characteristic and the value utilized, and tool progressive and improvement property meet the legal important document of novel patent fully, propose novel patent application then in accordance with the law.

Though the utility model discloses as above with a preferred embodiment, be not in order to limit the scope that the utility model is implemented.Anyly have the knack of this art; In spirit that does not break away from the utility model and scope, when doing a little change and retouching, promptly all equalizations of doing according to the utility model change and modify; Should be the utility model claim and contain, it defines and should be as the criterion with claim.

Claims

1. air inlet speed limiting mechanism, it is arranged on the manifold that is connected with Carburetor, and one with leaf valve that crankshaft room is connected between; And it is characterized in that; This air inlet speed limiting mechanism slightly is an inverted cone shape, and its upper end tool is slightly less than the upper shed of the mouth of pipe of manifold, and is contracted in gradually downwards by upper shed; The under shed that makes its lower end is much smaller than upper shed, and its taper body portion and under shed then place in the leaf valve.
