Abstract

The utility model belongs to the engine manufacture technical field, and in particular relates to an engine carburetor with improved structure, which comprises an oil tank, an air filter, a carburetor and an oil route pipe. The utility model is characterized in that an oil supply device is arranged between the carburetor and the oil tank, an oil inlet pipe of the oil supply device is connected with an oil outlet of the oil tank, and an oil outlet pipe is communicated with the oil supply device. The oil supply device is directly inserted into an air gate of the carburetor to correspond to a throat pipe center of the carburetor. Therefore, a straight pipe of the oil supply device is pressed to spray out fuel to increase the density of fuel for easy starting. The engine carburetor of the utility model has the advantages of, saving air resistant door structure and operation steel rope, increasing safety for operator of a grass cutter, starting operation of the grass cutter conveniently together with good economical benefits and a compact structure.

Description

A kind of motor carburetion device of architecture advances

Technical field

The utility model belongs to the engine manufacturing technology field, the motor carburetion device that particularly a kind of mowing machine is used.

Background technique

Engine and carburetor is the critical piece of lawn mower engine oil-feed system, traditional engine and carburetor adopts of the choke flap structure, by regulating the rotation aperture of chock plate pitman arm shaft, the aperture of control air flap, thereby utilize the variation of air mass flow, reach and control air fuel ratio.Operator for mowing machine, if adopt choke gate-type structure applications in engine and carburetor, must operate away from the position of mowing machine handle, this need increase the operation cable wire, not only increased manufacture cost, and when the handle folding, operate cable wire, have potential interference, thereby increase the danger of generation accident in the operation.

Summary of the invention

The purpose of this utility model is to set up an oilier, gives Carburetor by oilier with the fuel oil force feed, can save the cable wire operation like this, and make lawn mower engine carburetion apparatus structure be tending towards more reasonable, and is compacter.

Above-mentioned purpose of the present utility model can be achieved through the following technical solutions:

A kind of motor carburetion device of architecture advances comprises fuel tank, empty filter, Carburetor and oil circuit pipe is characterized in that an oilier is set between Carburetor and the fuel tank, and the oil inlet pipe of oilier is connected on the fuel tank oil outlet, link by oil outlet tube and oilier, the oilier straight tube is inserted in the carburetor throttle mouth;

Described motor carburetion device, feature are the trunnion centers of the corresponding Carburetor of oilier straight tube spout.

The utility model when engine start, utilizes oilier from the fuel tank oil suction by on the Carburetor pipeline oilier being set like this, and then, by the straight tube injected fuel of compressing oilier, fuel oil concentration in the time of can increasing engine start is convenient to starting.

The utility model not only makes motor carburetion apparatus structure compactness, save of the choke flap structure and operation cable wire, not only reduced the motor manufacture cost, and increased mowing machine operator's Security, make mowing machine operation starting more convenient, have good economic benefit.

Description of drawings

Fig. 1: structural representation of the present utility model;

Fig. 2: the sectional drawing of the utility model oilier.

In the diagram, 1 fuel tank, 2 fuel tank rubbers circle, 3 oilier oil inlet pipes, 4 oiliers, 5 oilier oil outlet tubes, 6 oilier straight tube I, 7 oilier straight tube II, 8 Carburetors,

Embodiment

During engine start, press the oilier leather cup, cause to form vacuum in the oilier oil inlet pipe, can make fuel from fuel tank 1 suck oilier 4 by oilier oil inlet pipe 3; Continue to press the oilier leather cup, fuel oil is constantly sent into oilier straight tube I6 and oilier straight tube II7 through oilier 4 by oilier oil outlet tube 5.Because oilier straight tube aperture is less, under the effect that constantly enhances pressure, fuel oil will inject the trunnion center of being located at Carburetor 8, thereby the enriching fuel oil be convenient to the motor quick starting with the fuel-displaced cross-drilled hole ejection of certain speed from oilier straight tube II7.

The utility model has replaced traditional of the choke flap structure by oilier is set, by regulating tubing pressure, oil mass is given in regulation and control, and not only control operation is convenient, and, can combine together with Carburetor, make motor starting characteristic better, effectively ensure the engine health operation.

Claims

1. the motor carburetion device of an architecture advances comprises fuel tank, empty filter, Carburetor and oil circuit pipe is characterized in that an oilier is set between Carburetor and the fuel tank, and the oil inlet pipe of oilier is connected on the fuel tank oil outlet, oil outlet tube and oilier link, and the oilier straight tube is inserted in the carburetor throttle mouth.

2. motor carburetion device according to claim 1, feature are the trunnion centers of the corresponding Carburetor of oilier straight tube spout.
