Abstract
The utility model relates to a spraying pipe type carburetor with a fixed choke. In the utility model, a main spraying pipe is designed into a cylindrical thin-wall structure and is installed in the whole chock in a projecting way; the pipe wall of the spraying pipe of the utility model is provided with a row of or a plurality of rows of micropores, and the sizes and the quantity of the micropores are designed according to the requirement of the atomization of gasoline, the gasoline supply quantity at the time of the maximum load of an engine, and the technological performance of the micropores. The air flow of air flowing through a choke part can be controlled by utilizing the opening size of a butterfly valve to change the vacuum degree of the choke part in any operating mode, and the quantitative regulation of the required supply quantity of the gasoline of the engine in any operating mode can be achieved.
Description
The utility model relates to constant choke carburetor.
Traditional constant choke carburetor utilization is regulated the unlatching size of the butterfly valve type closure that is installed in the trunnion rear and is controlled the quantity that enters the inflammable mixture in the engine cylinder, adjusts the rotating speed and the output power of motor.Just design is at the lower wall portion of trunnion for the main jet hydraulic fluid port, and air velocity is low herein, and is poor for the degree of grinding of the gasoline of jet ejection, also bad with the abundant mixing of air.The Carburetor of this fixed choke formula does not have the device according to the regulating working conditions oil mass of motor, only is provided with foam tube to play the inhibitory action of certain excessive oil spout, makes engine consumption higher, and blowdown is poor.But because its simple in structure, low cost of manufacture, advantage such as easy to maintenance at universal machine, as being extensive use of on the supporting petrol engine such as small generator, mowing machine, are also generally used on trail bike and motorbike.
The purpose of this utility model is to solve the disadvantage of constant choke carburetor oil consumption height, discharging difference, provides a kind of not only simple in structure, and the novel constant choke carburetor that oil consumption is low, discharging is good.
The design's Carburetor equally has each systems such as oil-feed, startup, idling-transition, main fuel feeding with traditional constant choke carburetor.
Designed the injection spray pipe of thin-wall tube-shaped structure in the main oil supply system, protrusion is installed in the whole fixed choke, the micropore of one row or number misarrangement position arrangement is set at barrel upper edge, airintake direction back side axial direction, the aperture is between 0.1-0.3mm, the size of micropore decides according to the manufacturability of fogging degree and processing, and the zone that air-flow easily produces eddy current is avoided in the setting of micropore as far as possible.The delivery volume of oil gas was set when the peak output that the quantity of micropore is set according to motor was exported.For the oil gas that makes foamed does not produce eddy current in jet pipe, and can produce normal direction spray power and in micropore, spray, produce better atomizing effect, be provided with fixing acicular structure spindle.But it can not play the effect of regulating oil mass, just plays the guide functions to oil gas.
The design's constant choke carburetor can be designed to two injection spray pipes or many injection spray pipes structure, and injection spray pipe is along the airintake direction linear array, and the setting of the oil spout angle of the micropore of back injection spray pipe will be avoided the injection spray pipe of front.
Accompanying drawing 1: the schematic representation of the fixed choke spraying tubular type Carburetor of single injection spray pipe.
Accompanying drawing 2: the schematic representation of the fixed choke spraying tubular type Carburetor of two injection spray pipes.
Now be described with reference to the accompanying drawings the design.
According to Fig. 1, the main oil supply system of this Carburetor comprises main jet 1, foam tube 2, injection spray pipe 3, spindle 4, butterfly valve 5.The 26S Proteasome Structure and Function of main jet and foam tube is the same with traditional Carburetor, injection spray pipe is original main jet pipe lengthening, extend in the whole trunnion, the partial design that injection spray pipe extend into trunnion becomes thin walled structures, injection spray pipe dorsad airintake direction designed a row or the micropore more than the row, the size of micropore mainly decides according to the fogging degree of oil gas and the manufacturability of processing, and what of the quantity of micropore will be satisfied required fuel delivery requirement when mating the engine design peak output.Because the micropore major part is arranged on trunnion air-flow high-speed region, so the better effects if of atomizing, mixing.Spindle is designed to acicular structure and is fixedly mounted in the middle of the injection spray pipe, mainly plays guide functions, does not make oil gas produce eddy current in injection spray pipe, can produce normal direction spray power, make the gasoline of foamed produce better atomizing effect when micropore sprays, and fuel feeding is stable.The unlatching size of butterfly valve, the air mass flow of having regulated the trunnion of flowing through just makes the degree of vacuum at trunnion place change, and adjusts the fuel injection quantity of injection spray pipe, satisfies the required mixed gas quantity of each operating mode of motor.
According to Fig. 2, installed in the fixed choke two injection spray pipes 3 ' and 3 ", injection spray pipe is along airintake direction design and installation, 3 " the micropore spray angle of injection spray pipe should be avoided 3 ' injection spray pipe, this design mainly is the Carburetor that satisfies the high-power petrol engine of coupling.
The design's carburetor relatively has the following advantages with former constant choke carburetor:
1, the design adopts the micropore oil spout of injection spray pipe, so the fogging degree of oil gas is good, has Be beneficial to the abundant burning of gasoline, improve the power output of engine, reduce the row of oil consumption and waste gas Put.
2, because the micropore of injection spray pipe major part designs the air-flow high-speed region at trunnion, spraying Effect is better, and originally the jet of fix-venturi carburetor is arranged on the bottom of trunnion, has caused The air-fuel mixture inequality, this design can be avoided the shortcoming of air-fuel mixture inequality.
The design's carburetor mainly is applicable to the petrol engine with the Small Universal machinery support, With trail bike and motorbike; Also can be used in automobile with on the carburetor, at secondary venturi Interior installation injection spray pipe reaches the purpose that reduces oil consumption and discharging.
Claims (3)
1. fixed choke spraying tubular type Carburetor is characterized in that: main oil supply system being provided with is installed in thin-walled cylinder in the whole trunnion hole injection spray pipe that declines, and is provided with a row or a plurality of rows micropore at the axial direction of the semicolumn tube wall at the back side of airintake direction; Fixing spindle has been installed in the injection spray pipe.
2. Carburetor according to claim 1, the pore size of the micropore on the cartridge type injection spray pipe and quantity decide according to fuel delivery and the requirement of gasoline atomizing, the manufacturability of capillary processing of full engine load.
