Abstract
The utility model relates to a carburetor, relating to a gas mixer. The utility model is composed of a body, a pull wire plunger piston mechanism, a main jet tube mechanism and an idle speed mechanism. The utility model is characterized in that a gas pipeline is directly communicated with a main jet outer cavity, a main jet tube and an idle speed flow passage, wherein, an air inlet and an idle speed the idle speed gas mixture outlet are arranged in the flow passage. The utility model has the advantage that the utility model is suitable for liquefied gas fuel, and the atmospheric pollution of the tail gas of a motorcycle can be greatly decreased. The utility model also has the advantages of simple structure, stable performance and economic performance increase.
Description
The utility model relates to gas mixer, and the vaporization that is specially adapted to Gas fuel motor vehicle mixes.
The fuel that present motorcycle engine is used mostly is gasoline, and its Carburetor is as gasoline and air vaporizing unit.It mainly is made up of body, backguy plunger mechanism, main jet pipe mechanism, idling mechanism, float chamber.It is not suitable for the gas mixing that liquifier acts as a fuel.And at present because petrolic carbon monoxide and hydrocarbon discharge amount are excessive, serious to atmospheric pollution, the environmental protection agenda is mentioned in the use of liquefied gas as fuel.
The purpose of this utility model provides the motorcycle vaporizer that a kind of liquid gas acts as a fuel and uses.
Scheme of the present utility model is: gas pipeline is installed in idling runner lower boss mouth, through hole is arranged at idling runner bottom and adjacent main jet exocoel bottom, the main jet pipe is installed in the main jet exocoel, main jet pipe lower outer diameter is littler than the internal diameter of main jet exocoel, and both sides are drilled with through hole, idle metering jet is equipped with at idling runner middle part, one air inlet is arranged at top, there is an idling mixed gas air outlet top, idling mixed gas air outlet is positioned at body throat total air outlet one side, be positioned at below, plunger edge simultaneously, when plunger is in the closed position, and still have certain clearance between the plunger.
Advantage of the present utility model is: simple in structure, gas mixed performance is stablized, and economic performance improves, and substitutes fuel oil with combustion gas and greatly reduces the pollution of motorcycle engine tail gas to air.
Accompanying drawing 1 is each part distribution stereogram of the utility model.
Accompanying drawing 2 is the utility model plan view.
Accompanying drawing 3 is the C-C sectional view of accompanying drawing 2.
The utility model is finished like this: the same with common Carburetor, body 11 tops are equipped with by dirt-proof boot 1, cable guide 2, plain washer 3, loam cake 4, loam cake packing ring 5, plunger return spring 6, plunger adjustment langrage spring 12, plunger adjustment screw 13, metering pin stage clip 7, metering pin collar 8, metering pin 9, plunger 10 and are formed the backguy plunger mechanism.The main jet pipe 17 of main jet pipe mechanism is installed in the body 11 bottom main jet exocoels 22, and main jet pipe 17 lower outer diameter of hollow are littler than main jet exocoel 22 internal diameters, and both sides are drilled with through hole.There is an auxiliary hole on main jet exocoel 22 right sides, block with copper ball 16, and main jet exocoel bottom corresponding position is drilled with a hole and communicates with adjacent idling runner 23, and main jet exocoel 22 is followed closely 20 and sealed with sealing plug screw 18, idling sealing respectively with idling runner 23 bottoms.Idling runner 23 lower left side of idling mechanism are equipped with suction tude 21, and liquid gas enters idling runner and main jet exocoel thus, and idle metering jet 19 is equipped with at idling runner middle part, and its top has an air inlet and top thereof that one idling mixed gas outlet is arranged.Air inlet communicates by total suction port of small pipeline with body 11 the right, one proportions of ingredients regulating mechanism is arranged therebetween, adjusting screw 15 by proportions of ingredients adjustment langrage spring 14 and proportions of ingredients forms, adjustment enters the air quantity size of idling runner, its principle is the same with common Carburetor corresponding mechanism, just adjusts the object difference.The idling mixed gas air outlet of idling runner top is positioned at body throat total air outlet one side, below, plunger 10 edges, and when plunger 10 was in closed condition, idling mixed gas air outlet and plunger below still had certain clearance.
The utility model and the common Carburetor main distinction are not establish float chamber, main amount mouth, liquid gas directly enters in the main jet pipe hollow in the main jet exocoel and the idling runner, and what another difference was that the idling air outlet flows out is mixed gas, rather than vaporization again after the outlet.
During use, work as foot pedal starting, produce negative pressure with the cylinder suction port in the engine cylinder, this negative pressure forces the negative pressure valve that connects with vaporizer to be opened, at this moment flow to vaporizer by the negative pressure valve liquid gas of opening with the gas situation and enter motor, make the engine ignition starting, after engine start during the low speed operating mode, it is idling mode, because the vaporizer plunger is not pulled up, this moment, carburetor hollow throat place negative pressure maximum point was positioned at the place, idling air outlet of plunger front end, and the vacuum degree deficiency at main injection jet place is with the combustion gas sucking-off, the air mixing that combustion gas is at this moment come in by idle metering jet and idling air jet from suction tude, and mixed gas is crossed trunnion and is entered motor from the idling air outlet of trunnion, by an amount of idling mixed gas of proportions of ingredients screw adjustment, with idling or the low speed operating mode that satisfies motor.When plunger pull-up gradually, the degree of vacuum at trunnion place descends, at this moment the degree of vacuum maximum point is shifted to main jet pipe top, combustion gas is just by suction tude, main jet pipe and the ejection of metering pin annular space, the air mixing of coming in suction port enters motor then, and this moment is by idling air outlet and the common air feed of high speed air outlet hole.The certain altitude negative pressure is little not to be had aspiration to the idling air outlet and goes out when plunger rises, at this moment all by main jet pipe air feed.
Claims (2)
1. vaporizer, comprise body, the backguy plunger mechanism, main jet pipe mechanism, idling mechanism, it is characterized in that: gas pipeline is installed in idling runner lower boss mouth, through hole is arranged at idling runner bottom and adjacent main jet exocoel bottom, the main jet pipe is installed in the main jet exocoel, main jet pipe lower outer diameter is littler than the internal diameter of main jet exocoel, and both sides are drilled with through hole, idle metering jet is equipped with at idling runner middle part, and an air inlet is arranged at top, and there is an idling mixed gas air outlet top, idling mixed gas air outlet is positioned at body throat total air outlet one side, be positioned at below, plunger edge simultaneously, when plunger is in the closed position, and still have certain clearance between the plunger.
2. a kind of vaporizer according to claim 1 is characterized in that the air inlet on idling runner top communicates by total suction port of small pipeline with body the right, and a proportions of ingredients regulating mechanism is arranged therebetween.
