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, and there are more and more problems with the existing cylinder form. The invention provides a car air intake device

Embodiment 1

[0028] Such as Figure 1 to Figure 3 As shown, a kind of automobile air intake device, comprises distributing chamber 10, and described distributing chamber 10 is the sealed chamber surrounded by box body 2 and cover plate 23, and described distributing chamber 10 is connected with air inlet 22 and multiple Each air outlet 1 also includes a number of control parts equal 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 22;

[0029] A connection hose 26 is connected to the air outlet 1, and the other end of the connection hose 26 is connected to a cut-off valve body 24, and a fluid circulation channel is arranged in the cut-off valve body 24, and the connection hose 26 is connected to On the inlet end of the fluid communication channel, the control part and the isolation valve body 24 are used to control the communication status of each fluid communica...

Embodiment 2

[0033] 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 22 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 22 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 22.

[0034] In order to reduce the influence of the air outlets 1 on each other during the staggered communication process of the air outlets 1 after the air source enters the distribution chamber 10, the bottom surface of the box body 2 or the cover plate 23 is also provided with the number of groups and the air outlet 1 The number of deflectors 21 is eq...

Embodiment 3

[0036] 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 24, 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 .

[0037] 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 an automobile gas inlet device. A distributing cavity is a sealed cavity enclosed by a box body and a cover plate, and further comprises control parts of which the quantity is as many as that of gas outlets, wherein a gas inlet and the plurality of gas outlets are connected on the distributing cavity; the shape of the distributing cavity is in central symmetry; the gas outlets are symmetrically arranged relative to the gas inlet; a connecting hose is connected on each of the gas outlets; the other ends of the connecting hoses are connected with isolating valve bodies; fluid circulating channels are arranged in the partition valve bodies; the connecting hoses are connected at inlet ends of the fluid circulating channels; the control parts and the isolating valve body are applied to controlling a circulating state of each fluid circulating channel in a one-to-one correspondence manner. The automobile gas inlet device is convenient to realize equal-flow gas exhausting of each gas outlet, so that balanced power output of each gas cylinder is conveniently realized, and the mounting is convenient.

Description

technical field [0001] The invention relates to the field of fuel distribution devices for gas vehicles, in particular to a vehicle air intake device. 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 connected to the ...
