Abstract
The utility model discloses a carburetor capable of improving low-temperature start effect. The carburetor capable of improving the low-temperature start effect is arranged on a general gasoline engine under 10 KW. The carburetor capable of improving the low-temperature start effect comprises a mixing chamber, an oil chamber and a spray pipe which is communicated with the mixing chamber and the oil chamber. A choke valve is arranged at the air inlet end of the mixing chamber. An air damper is arranged at the air outlet end. An idling air jet is formed in the side of the choke valve. A through hole is formed in the pipe wall, corresponding to the air outlet of the idling air jet, of the spray pipe. The idling air jet is communicated with the through hole of the pipe wall of the spray pipe. A connecting hole which is communicated with the idling air jet is formed in the carburetor. A connecting head is arranged in the connecting hole. The connecting hole is connected with an air pump. With the structure, the general gasoline engine under 10 KW still can be smoothly started when the environment temperature is 5-10 DEG C below zero.
Description
Technical field
The utility model relates to a kind of Carburetor, relates in particular to a kind of Carburetor that improves the cold-starting effect.
Background technique
The existing following general-purpose petrol engine of 10KW generally is to adopt handle tray to start, the Carburetor body is colder during startup, fuel-oil atmozation amount in the mixing chamber is smaller, can not meet the requirements of oil-gas ratio, therefore can not normally start a machine, this moment, Carburetor was by adjusting choke valve position, make it be in little closing, therefore air inflow reduces, thereby oil-gas ratio is increased, but this regulated quantity is limited, especially when ambient temperature is subzero 5 ~ 10 degrees centigrade, the atomization quantity of gasoline is inadequate, therefore can't start.
Summary of the invention
When the utility model purpose is to provide a kind of ambient temperature to be subzero 5 ~ 10 degrees centigrade, still can start smoothly the petrolic Carburetor that improves the cold-starting effect.
To achieve these goals, the technical solution of the utility model is: a kind of Carburetor that improves the cold-starting effect, be arranged on the following general-purpose petrol engine of 10KW, and it comprises mixing chamber, accumulator and the jet pipe that is communicated with mixing chamber and accumulator; Described mixing chamber inlet end is provided with chock plate, and the outlet side is provided with closure; Described chock plate one side is provided with idling air jet, corresponding idling air jet outlet side is provided with through hole on the tube wall of jet pipe, idling air jet is connected with through hole on the jet pipe tube wall, described Carburetor is provided with the attachment hole that is connected with idling air jet, be provided with joint in the described attachment hole, joint is connected with extraction pump.
The utility model adopts above technological scheme, when the following general-purpose petrol engine of 10KW is subzero 5 ~ 10 degrees centigrade of startups in ambient temperature, by extraction pump the air pressure in the mixing chamber is reduced in advance, therefore the gasoline in the accumulator passes through jet pipe, spray more gasoline and enter mixing chamber and air atomizing, therefore the gasoline concentration of this atomizing oil gas is higher, even when ambient temperature is subzero 5 ~ 10 degrees centigrade, the following general-purpose petrol engine of 10KW also can successfully start.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a kind of structural drawing that improves the Carburetor of cold-starting effect of the utility model;
Fig. 2 is the sectional drawing of A-A among Fig. 1;
Fig. 3 is the sectional drawing of B-B among Fig. 1.
Embodiment
Shown in one of Fig. 1 to Fig. 3, a kind of Carburetor that improves the cold-starting effect of the utility model is arranged on the following general-purpose petrol engine of 10KW, and it comprises mixing chamber 1, accumulator 2 and the jet pipe 3 that is communicated with mixing chamber 1 and accumulator 2; Described mixing chamber 1 inlet end is provided with chock plate 11, and the outlet side is provided with closure 12; Described chock plate 11 1 sides are provided with idling air jet 4, corresponding idling air jet 4 outlet sides are provided with through hole 31 on the tube wall of jet pipe 3, idling air jet 4 is connected with through hole 31 on jet pipe 3 tube walls, described Carburetor is provided with the attachment hole 5 that is connected with idling air jet 4, be provided with joint 51 in the described attachment hole 5, joint 51 is connected with extraction pump 6.
Working principle of the present utility model is: at first chock plate 11 is adjusted into little state that closes, and with closure 12 standard-sized sheets, when pulling engine hand pulling dish, by extraction pump 6 air pressure in the mixing chamber 1 is reduced in advance, therefore the gasoline in the accumulator 2 sprays more gasoline and enters mixing chamber 1 and air atomizing by jet pipe 3, and the gasoline concentration of this atomizing oil gas is higher, when even ambient temperature is subzero 5 ~ 10 degrees centigrade, the following general-purpose petrol engine of 10KW still can start smoothly.
