Problems solved by technology

[0004] In view of the above-mentioned existing gas flowing in the pipeline, because the internal pressure of the front section is greater than that of the rear end, this makes the output pressure of the output end close to the intake end greater than the output end pressure of the output end far away from the intake end, resulting in uneven power distribution of each cylinder. Uniformity, which affects the uniformity of vehicle power output in the short term, and long-term operation in this working condition will develop into uneven wear of the cylinder. At the same time, there are more and more existing cylinders. The invention provides a fuel supply Gas device

Embodiment 1

[0031] Such as Figure 1 to Figure 3 As shown, a fuel supply device for automobiles includes a distribution cavity 10, which is a sealed cavity surrounded by a box body 2 and a cover plate 23, and an air inlet 24 and an air inlet 24 are connected to the distribution cavity 10. A plurality of air outlets 1 also include control parts equal in number to the number of air outlets 1, the shape of the distribution chamber 10 is centrally symmetrical, and the air outlets 1 are arranged symmetrically with respect to the air inlet 24;

[0032] An electric heating block 21 is also embedded in the box body 2, and a hot water flow channel 22 is also distributed in the box body 2;

[0033] A connection hose 28 is connected to the air outlet 1, and the other end of the connection hose 28 is connected to a cut-off valve body 27, and a fluid flow channel is arranged in the cut-off valve body 27, and the connection hose 28 is connected to On the inlet end of the fluid communication channel, t...

Embodiment 2

[0038] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As shown, as a simple arrangement of distribution chamber 10, air inlet 24 and air outlet 1, the box body 2 is in the shape of a cylinder, and the cover plate 23 is a plate-shaped structure connected with the box body 2 by threads or bolts. The distribution cavity 10 is the hollow part of the box body 2 , the air inlet 24 is arranged at the center of the bottom surface of the box body 2 , and the air outlet 1 is arranged on the bottom surface of the box body 2 and is annularly evenly distributed with respect to the air inlet 24 .

[0039] In order to reduce the influence of the gas outlets 1 during the staggered communication process of the gas outlets 1 after the gas source enters the distribution chamber 10, the bottom surface of the box body 2 or the cover plate 23 can also be provided with groups and gas outlets. 1 equal number of deflectors 25, the deflectors 25 and the...

Embodiment 3

[0041] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As mentioned above, the control part includes a cut-off valve core 3, an iron rod 4, a spring 6, a connecting cylinder 7, a threaded post 8 and a coil 5. The ends are fixedly connected, and the iron rod 4 and the spring 6 are all located in the connecting cylinder 7, the connecting cylinder 7 is connected on the block valve body 27, the threaded column 8 is threadedly connected with the connecting cylinder 7, and the threaded column 8 goes deep into one end of the connecting cylinder 7 and The free end of the spring 6 is in contact, the axial direction of the threaded column 8 is parallel to the axial direction of the spring 6 , and the coil 5 is sleeved on the connecting cylinder 7 .

[0042] In this structure, the magnetic field generated after the coil 5 is energized acts on the iron rod 4 to form an electromagnet. When the power is not applied, the elastic stress of the ...

Abstract

The invention discloses a vehicle fuel gas supply device which comprises a distribution chamber. The distribution chamber is a sealed cavity enclosed by a box and a cover plate, and an air inlet and a plurality of air outlets are connected on the distribution chamber; the vehicle fuel gas supply device further comprises control portions identical to the air outlets in number, the distribution chamber is arranged in central symmetry, and the air outlets are symmetrically arranged relative to the air inlet; electric heating blocks are imbedded in the box, and hot-water flows are distributed in the box; each air outlet is connected with a connecting hose, the other end of each connecting hose is connected with an isolating valve, and the control portions are in one-to-one correspondence to the isolating valves. Equal-discharge and equal-size exhaust of each air outlet are conveniently realized, balanced power output of each cylinder is conveniently realized, good fuel output can be provided within a short time, vehicle starting time is favorably shortened, and convenience in mounting is achieved.

Description

technical field [0001] The invention relates to the field of fuel distribution devices for gas vehicles, in particular to a fuel gas supply device for vehicles. Background technique [0002] The use of natural gas as fuel for vehicle engines can not only greatly reduce vehicle exhaust pollution, but the use of natural gas is also an effective measure to alleviate the current situation of rapid growth in vehicle ownership, aggravated environmental pollution and shortage of oil resources. Oil-to-gas conversion is being popularized and promoted around the world. In my country, many buses, taxis and even private vehicles use natural gas as fuel. [0003] In gas vehicles, the electronically controlled gas injection system is an essential part, and its working performance directly affects the utilization rate of gas and the output power of the engine. In the existing cylinder gas system, natural gas enters the In the injection rail, the output end of the injection rail is connect...
