Abstract
The utility model discloses a kind of gasoline engine carburetor, including air throttle rocking arm, spacing positive stop and the air throttle adjusting screw on the positive stop is carried out to air throttle rocking arm, it is characterised in that：Buffer gear is installed between the air throttle rocking arm and the positive stop.Using gasoline engine carburetor of the present utility model, the control tourist bus problem of engine is can solve the problem that.
Description
Technical field：
The utility model is related to gasoline engine field, more particularly to the carburetor on gasoline engine.
Background technology：
At present, for general gasoline engines, no-load running is unstable（It is commonly called as tourist bus）It is one of most common phenomenon of the failure.Generally
Situation, solving tourist bus can be solved by reducing speed governing power, adjustment carburetor internal structure two ways.And both sides
Formula has its drawback：Reducing speed governing power can direct losses engine output；Adjustment carburetor internal structure generally needs
Consider the influence to discharging, be balanced therebetween in tourist bus, exhaust emissions.In summary reason, solves tourist bus at present
Conventional method can all have influence on the performance and exhaust emissions of engine.
Utility model content：
The purpose of this utility model be provide one kind can solve the problems, such as zero load tourist bus and do not interfere with engine performance and
The gasoline engine and its carburetor of exhaust emissions
In order to achieve the above object, the utility model is realized in：A kind of gasoline engine carburetor, including air throttle shakes
Arm, spacing positive stop and the air throttle adjusting screw on the positive stop is carried out to air throttle rocking arm, its
It is characterised by：Buffer gear is installed between the air throttle rocking arm and the positive stop.Using aforesaid way, can solve
The certainly problem of gasoline engine zero load tourist bus so that engine stabilizer operation when unloaded, and ensure that the performance and tail of gasoline engine
Gas discharge capacity.In addition, such setting structure is simple, with low cost.
In order to it is further simplify structure, the buffer gear for be arranged on the air throttle rocking arm and the positive stop it
Between elastic component.
Simplify structure and reduces cost in order to further, the elastic component is spring.
Simplify structure and saving manufacturing cost in order to further, the spring is arranged on the adjustment spiral shell on the positive stop
Nail on.
In order to further improve the steadiness of structure, the tail end face of the adjusting screw is provided with mounting groove, it is described
Spring one end is arranged in the mounting groove.
Simplify structure in order to further, the spring is arranged on the positive stop.
In order to further it is cost-effective, the spring is welded to connect with the positive stop.
Simplify structure in order to further, the spring is arranged on the air throttle rocking arm.
In order to further it is cost-effective, the spring is welded to connect with the air throttle rocking arm.
A kind of gasoline engine including carburetor described above.
Using gasoline engine carburetor of the present utility model, the premise of gasoline engine performance and exhaust emissions can not influenceed
Under, solve the problems, such as engine zero load tourist bus so that engine stabilizer operation when unloaded.And, also cause the matching of carburetor
Become simpler.In addition, the utility model simple structure, with low cost.
Brief description of the drawings：
Fig. 1 is the structure chart of embodiment 1；
Fig. 2 is the structure chart of embodiment 2；
Fig. 3 is the structure chart of embodiment 3.
Specific embodiment：
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These implementation methods are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim scope required for protection.
