Description

technical field [0001] The invention relates to the technical field of general engines, in particular to an electronically controlled double-chamber gas mixer. Background technique [0002] Currently, two-cylinder general-purpose engines are usually used for generators, fire pumps, washing machines or marine power, etc. The fuels with better economy are mainly liquefied petroleum gas (LPG) and natural gas (NG). When a two-cylinder engine uses liquefied petroleum gas and natural gas, it usually uses a pressure reducing valve to reduce the pressure of liquefied petroleum gas (LPG) and natural gas (NG), then connects it to the mixer, and mixes it with air through the mixer It is supplied to the engine, and the supply of mixed gas is adjusted by the throttle valve. At different altitudes, the supply of gas is not easy to adjust, and the combustion efficiency is affected. The gas supply channel is processed by the process. Due to the limitation of the drilling process, the gas ...
