Abstract
The present invention discloses a positive-pressure fuel gas injection and mixing unit of a gas engine. The unit is composed of a fuel gas inlet part (1), a hexagonal screw-down part (2) and an air inlet pipe insertion part (3) which are integrally connected together. The air inlet pipe insertion part (3) is circumferentially partitioned into multiple rows of longitudinally arranged air injection pores (4). The sum of the sectional areas of all of the ten to fifty air injection pores (4) is two times larger than the drift diameter area of the fuel gas inlet part (1). The angle of the inclined plane of the inserted part of the air inlet pipe insertion part (3) is 15 degrees to 60 degrees. The unit has the advantages of simple structure, small volume, convenient operation and adjustment, reliable operation performance, wide application range, safe use, simple assembly and easy maintenance.
Description
Technical field
The present invention relates to the device that a kind of gas engine combustion gas malleation sprays into mixing.
Background technique
The method that the combustion gas malleation of present China gas combustion automobile sprays into mixing mainly is to adopt venturi mixer and proportioning mixer, combustion gas is entered the intake manifold by mixer mix.The processing technique difficulty of mixer is big, part is many, cost is high, and often in installation process, be subjected to the restriction of engine air inlet tube size, install very difficult, need block or the brachymemma suction tude, suction tude is caused non-response damage, especially for causing certain difficulty with the transformation of car gasification.
Summary of the invention
The objective of the invention is: a kind of gas engine combustion gas malleation sprays into the device of mixing.
The object of the present invention is achieved like this:
A kind of gas engine combustion gas malleation sprays into the device of mixing, it is characterized in that: the whole linkage structure that it is the fuel gas inlet part, six sides install screwed portion, suction tude insertion portion.
Described suction tude insertion portion is divided into the jet aperture of many row's files on circumference.
The quantity of described jet aperture is 10～50, and all aperture sectional area sums are 2 times of fuel gas inlet part latus rectum.
15 °～60 ° of described suction tude insertion portion insertion portion bevel angles.
Advantage of the present invention is: compared with prior art, that the present invention not only has is simple in structure, volume is less, operation is easy to adjust, the advantage of reliable working performance, wide accommodation, but also have safe in utilization, simple, maintenance be installed be easy to advantage.The present invention is particularly suitable for being suitable in the fuel supply system of gas-fueled vehicles.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is processed with the structural representation of jet aperture for the present invention;
Fig. 3 is a scheme of installation of the present invention.
Embodiment
A kind of gas engine combustion gas malleation sprays into the device of mixing, it is characterized in that: it is the whole linkage structure that fuel gas inlet part 1, six sides install screwed portion 2, suction tude insertion portion 3.
Described suction tude insertion portion 3 is divided into the jet aperture 4 of 3 row's files according to 90 ° of branch chamfers in 180 ° of circumference.
The quantity of described jet aperture 4 is 35, and all aperture sectional area sums are 2 times of fuel gas inlet part (1) latus rectum.
45 ° of described suction tude insertion portion 3 insertion portion bevel angles
Be provided with fuel gas inlet part 1, six sides installation screwed portion 2, the outlet of suction tude insertion portion 3 low-pressure gases and jet aperture 4, as Fig. 2, in actual project installation, can select for use different gas engine combustion gas malleations to spray into the device of mixing flexibly with size according to the position of engine air inlet tube.During installation such as Fig. 3, in the suitable hole that is complementary with gas mixing unit of processing, positions of engine air inlet tube 8, with gas mixing unit 5 insertions.Add the gasket seal 7 that high temperature resistant oil-resistant rubber material is made then, at last with locking nut 6 lockings.The threaded interface of outer cone in fuel gas inlet part 1 employing standard can be connected with the gas hose of standard easily.The suction tude insertion portion 3 of this device in the ordinary course of things, when the engine air inlet tube long enough, in the time of can guaranteeing that installation and combustion gas fully mix with air, adopts structure shown in Figure 1, and design and processing are all very simple; Closer from air intake branch when the mounting point, in order to save installing space, the while is in order to guarantee that combustion gas fully mixes with air, can adopt structure shown in Figure 2.
Claims (4)
1, a kind of gas engine combustion gas malleation sprays into the device of mixing, it is characterized in that: the whole linkage structure that it is fuel gas inlet part (1), six sides install screwed portion (2), suction tude insertion portion (3).
2, gas engine combustion gas malleation according to claim 1 sprays into the device of mixing, it is characterized in that: described suction tude insertion portion (3) is divided into many row's jet apertures of file (4) on circumference.
3, gas engine combustion gas malleation according to claim 2 sprays into the device of mixing, it is characterized in that: the quantity of described jet aperture (4) is 10～50, and all aperture sectional area sums are 2 times of fuel gas inlet part (1) drift diameter area.
4, gas engine combustion gas malleation according to claim 1 and 2 sprays into the device of mixing, it is characterized in that: 15 °～60 ° of described suction tude insertion portion (3) insertion portion bevel angles.
