Abstract

The invention discloses a fuel gas mixer structure. According to the fuel gas mixer structure, air enters a main channel through an air inlet, fuel gas enters from a fuel gas inlet, and then enters an arc-shaped pipe through a gas inlet groove of the arc-shaped pipe be mixed with the air entering the arc-shaped pipe, due to the fact that the gas inlet groove is a square groove, the fuel gas can enter the arc-shaped pipe in a sheet shape along the square gas inlet groove, and in addition, due to the fact that the arc-shaped pipe is in an arc shape, the gas inlet groove is provided with a first step portion, and the inner wall of the arc-shaped pipe is provided with a second step portion opposite to the first step portion, and when air enters the arc-shaped pipe from the air inlet, the sudden cross section change enables the air to form swirling flow at the first step portion and the second step portion. The gas discharged from the gas inlet groove can be more uniformly mixed with air under the swirling flow effect, the mixing efficiency and effect are obviously improved, the concentration control of combustible gas is more stable, and the acceleration performance of an engine is further ensured.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a gas mixer structure. Background technique [0002] The engine that uses gas as fuel has a specific gas supply pipeline, which basically includes a pipeline for delivering gas, a pipeline for delivering air and a mixer, the pipeline for delivering gas is connected to the pipeline for delivering air and the mixer, and the mixer is connected to the engine The connection forms the mixture into the engine. [0003] The existing mixer is equipped with an air inlet and a gas inlet, and the gas and air are mixed at the valve plate of the mixer. This kind of mixing is realized by the diffusion of air and gas inside the mixer, and the mixing effect of the gas is not good. Well, especially during the acceleration process, the concentration control of combustible gas is unstable, which directly leads to poor acceleration performance of the engine, and in severe cases, directly leads to se...
