Abstract
The present invention relates to a method for improving the quality of mixed combustible gas provided by a carburetor, which comprises a method making use of anti-blocking multi-point nozzles on a main oil jetting tube of a carburetor to jet oil, and a method making use of multiple points and multiple directions on the main jetting tube of the carburetor to jet oil.
Description
Technical field
What the present invention relates to is a kind of Carburetor, and particularly a kind of Carburetor that improves quality of combustible mixed gas belongs to the petrol engine field.
Background technique
The leading portion intake duct passage section of Carburetor all is designed to shrink spray shape pipe according to the air current flow direction in the prior art, and the place reaches smallest cross-sectional at main oil sprayer, becomes aditus laryngis.By the air-breathing pressure difference that forms of motor, promote ambient air and flow into carburetor inlet.Manage principle according to Wen Deli: at the trunnion place, air-flow will reach peak flow rate (PFR).The boundary layer theory that flows according to real fluid: the flow velocity of air on the aditus laryngis wall is zero, near leaving the aditus laryngis wall (in the boundary layer) though airspeed increase gradually, but also be lower than the airspeed of aditus laryngis central position, so oil spout position of Carburetor, from improving high velocity air the angle of gasoline elaioleucite bump, pulverizing, atomizing is considered, preferably be chosen in the aditus laryngis central position, and in order to strengthen oil atomizing, design nozzle opening small and dense again mostly, but usually cause nozzle opening to stop up.The tradition Carburetor is in motor groundwork zone, what of main oil supply system fuel delivery, only rely on unique being positioned to carry out fuel-flow control and oil spout fuel feeding by main jet oilhole and the circular crosssection that the spindle that moves with valve constitutes near the aditus laryngis bottom wall, and this annular oil spout cross section will increase gradually along with the increase of engine load.This large size oil spout is difficult to receive the effect of oil atomizing, Pen Chu gasoline deviates from air-flow peak flow rate (PFR) district, aditus laryngis position again simultaneously, to gasoline atomizing and mix to produce and do not influence, when motor enters higher load or big load operation, spindle will be lost the regulating action to fuel delivery, though Carburetor is provided with main foam tube, introduce portion of air and gasoline from the external world and be mixed into foam gasoline, fuel delivery has been carried out adjusting to a certain degree, but effect is quite limited, look into new discovery according to retrieval to prior art, many technology are existing did some concrete improvement respectively to the various defectives of Carburetor, as: Japan Patent, patent publication No. is: JP6-10769A, name is called: a kind ofly improve the method that Carburetor provides quality of combustible mixed gas, this patent specifically discloses following technical characteristics and " has utilized the method for multiple spot and multidirectional oil spout on the main spray tube of carburettor ".And for example: Chinese patent the last 0021327 atomizing Carburetor, strengthen fuel-oil atmozation by Electromagnetic Control, Chinese patent 92231838 automobiles secondary-atomizing Carburetor, former carburetion wall has been made to improve above-mentioned two technology of design all exists structure complicated, and because of the oil gas problem that crosses still unresolved, Carburetor is difficult to provide quality burning mixture preferably to motor, and the oil consumption of motor and exhaust index are difficult to descend.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of Carburetor that improves quality of combustible mixed gas is provided, make it improve Carburetor and provide the burning mixture of better quality to motor, various Carburetors still all have systems such as air inlet, startup, idling, various load, load transition and main fuel feeding simultaneously.
The present invention is achieved by the following technical solutions: the present invention has multiple spot and multidirectional oil spout on main spray tube of carburettor, main jet oil pipe upper edge axial direction is provided with some little mouthful of long or short oil spout straight troughs or some little mouthful oil spout spiral chute is set in the circumference different azimuth, little spout quantity of distributed throughout and density can need the oil mass decision according to the various load conditions of motor on the main jet oil pipe, the little mouth of oil spout is arranged to multidirectional on the main jet oil pipe, substitute the unique large size annular of former Carburetor oil spout cross section with these numerous little spouts, improve the oil atomizing intensity (primary atomization) of gasoline, simultaneously because each oil spout Wei Kou cross section is very little, the amount of fuel of its ejection also seldom can implement to make the trace to fuel delivery to regulate.Setting fuel-flow control bar lower end is a small cone body, the stage casing is one section longer conical section, back segment is one section ovaler shell of column, when the jointing place of cylindrical section and conical section should be positioned at plunger throttle valve or vacuum cock valve and is in buttoned-up status, cylindrical section can cover little jets all on the spray bar fully, and the cylindrical section afterbody is provided with five fuel delivery regulating tanks.
Conicle when the lower end will help a gasoline of coming in from main gauge hatch water conservancy diversion around main foam tube uniformly.Even the fuel-flow control bar is when adapting to bigger load of motor or big load operation, main foam tube of insertion that can be darker or main foam top still, can improve foam gasoline oil, gas mixing uniformity in advance.
Back segment both can guarantee to cover fully all little spouts on the main jet oil pipe, again can be according to the size of starting to load, and the little jet of part on the opening and closing main jet oil pipe.Five the fuel delivery regulating tanks and the collar of back segment are used, and select different annular grooves for use, and promptly the concentration of can regulate burning mixture can be located in throttle valve or vacuum cock valve again.
The multiple spot oil spout can improve the fogging degree of gasoline once more, makes oil, gas mix more even simultaneously.Oil spout point unique in the former main oil supply system of Carburetor is positioned near the aditus laryngis bottom wall, because it has departed from aditus laryngis air-flow peak flow rate (PFR) district, air-flow is less to elaioleucite collision pulverizing dynamics, influence the raising of fogging degree, the main jet oil pipe is along with long-round-shape aditus laryngis long axis direction runs through whole aditus laryngis, numerous little oil spout point just is distributed on the main jet oil pipe of aditus laryngis central position, boundary layer theory according to real fluid, the gasoline particulate that the little oil spout point of the overwhelming majority ejects can be distributed in aditus laryngis air-flow peak flow rate (PFR) district, the gasoline particulate of crossing through osculum oil spout primary atomization is once more through the gasoline particulate (secondary-atomizing) of high velocity air impact comminution Cheng Gengxiao, further improved the fogging degree of gasoline, the multidirectional of little mouthful of setting of oil spout on the main jet oil pipe, cause the petrol-injected multidirectional, more help oil, the even mixing of gas.
The present invention has substance and remarkable progress, in Carburetor, realize the multidirectional oil spout of multiple spot of fuel oil, can improve oil, gas evenly mixing in advance and an oil atomizing degree in main foam tube, and in aditus laryngis air-flow peak flow rate (PFR) district, fuel oil energy atomized once more by high velocity air (secondary-atomizing), make the fogging degree of gasoline improve and further improve the uniformity of oil, gas mixing more, and the inflammable gas of different oil, gas ratio can be provided for the motor different load stage.Applicability of the present invention is strong, can obviously reduce engine consumption and significantly improve engine emission, has tangible economic benefit and social benefit.
