Description

technical field [0001] The invention belongs to the technical field of gas engines, and in particular relates to a low-pressure gas device for a gas engine. Background technique [0002] The gas device of the existing gas engine is generally composed of a decompression regulator and a mixer (Venturi or proportional type). This kind of gas device can be compared with the air in a relatively accurate ratio after the gas with a stable pressure is decompressed and stabilized. Mixing, the gas concentration remains basically unchanged, which can provide a relatively stable mixture for the engine. However, for unstable gas (pressure fluctuations, intermittent gas supply) whose pressure is lower than atmospheric pressure (for example: oil field associated gas, biogas, gas gas, etc.), due to the characteristics of unstable gas supply of low-pressure gas, the gas mixed with it The air must constantly change and adjust as the pressure changes. The existing gas device cannot guarantee...
