Problems solved by technology

When the combustion chamber is ignited, no matter whether the gas is excessive or insufficient, the ratio of gas to air will deviate from the optimal point, and the combustion efficiency of gas will decrease, which will not only cause waste of gas, but also increase the substandard components in the exhaust gas, which cannot meet the increasing demand. Strict gas emission standards

Embodiment 1

[0030] Such as Figure 1 to Figure 4 As shown, the stabilized gas distributor of this embodiment includes a tubular body 1, and the inside of the body 1 is a tubular buffer chamber 101. The body 1 has a gas inlet 102 and two gas outlets communicating with the buffer chamber 101. 103, two fixed straps 104 and a section of closed pipe 105 are also provided on the body 1. The position and quantity of the fixed straps 104 can be flexibly set according to the actual installation environment, and need not be limited to Figure 1 to Figure 4 situation shown in . The closed pipe 105 has an inner hexagonal plug 2 as a closed bottom, and the inner hexagonal plug 2 is screwed on the body 1 in a threaded manner. A piston 4 and a pressure stabilizing spring 3 are arranged in the closed pipeline 105 , and the piston 4 can slide in the closed pipeline 105 . The pressure stabilizing spring 3 is arranged between the piston 4 and the inner hexagonal plug 2 , its first end is connected with t...

Embodiment 2

[0035] On the basis of Embodiment 1, the difference of this embodiment is that the number of gas outlets 103 is increased according to the number of cylinder positions of the engine cylinder block. For example, for a four-cylinder engine, four gas outlets 103 are used; for a six-cylinder engine, six gas outlets 103 are used. Since this change is easily imagined by those skilled in the art, it will not be described in conjunction with the accompanying drawings.

[0036] After increasing the number of gas outlets 103, the transient fluctuations of airflow generated in the buffer chamber 101 will also increase accordingly. In order to eliminate this adverse effect, the inner diameter of the buffer chamber 101 in this embodiment is at least twice the inner diameter of the gas outlet 103 , so that the gas stored in the buffer chamber 101 can be used to buffer the transient fluctuation of the air flow, and enhance the air pressure stability during gas distribution. After actual tes...

Abstract

The invention discloses a pressure-stabilizing fuel gas distributor which comprises a tubular body. A tubular buffer cavity is positioned in the body, the body is provided with at least one fuel gas inlet communicated with the buffer cavity and at least two fuel gas outlets and is further provided with an air pressure buffering device, and the air pressure buffering device is used for absorbing transient fluctuation of air pressure in the body. According to the pressure-stabilizing fuel gas distributor, in the fuel gas distribution process, the transient fluctuation of the air pressure in a gas transmitting pipe can be buffered and absorbed, the gas supply process is more stable, and the gas supply requirements of a multi-cylinder gas engine are met.

Description

technical field [0001] The invention relates to a gas distributor, in particular to a pressure-stabilizing gas distributor for a multi-cylinder gas engine. Background technique [0002] When a multi-cylinder gas engine is working, gas needs to be delivered to each cylinder position. The traditional way of gas delivery is to use pipelines to transport gas from the gas source to the combustion chamber of each cylinder position, and set a control valve on the pipeline to control the flow of gas. Open the control valve, and the gas will enter the combustion chamber; after the gas supply is full, close the control valve to cut off the air flow. During the process of gas transportation from the gas source to each cylinder position, gas distribution is required, that is, the single output of the gas source is distributed into multiple outputs according to the number of cylinder positions, so that the gas can enter each cylinder position. This gas distribution is generally accompl...
