Problems solved by technology

However, due to its simple structure, the mixing effect of combustible gas is not good, especially in the acceleration process, the concentration control of combustible gas is unstable, which directly leads to poor acceleration performance of the engine, and serious engine misfire or backfire failure due to poor combustion. Affects engine performance and safety

Embodiment Construction

[0020] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0021] see figure 1 , figure 2 and image 3 , the engine mixer includes: a mixer body 1, a tubular spool 2 located inside the mixer body 1, a mixer adapter 4 connected to the mixer body 1, and a disturber located between the mixer body 1 and the mixer adapter 4 Fluid3. Wherein, the mixer body 1 is tubular, and the inner cavity is divided into a mixing chamber 11 located in the middle, an air inlet 12 located at the right end of the mixing chamber 11, and a mixed gas outlet 13 located at the left end of the mixing chamber 11. The upper edge of the inner wall of the mixing chamber 11 is Circumferentially, an annular natural gas inlet groove 14 and a natural gas inlet 15 extending outward from the annular natural gas inle...

Abstract

The invention discloses an engine mixer. The engine mixer comprises a mixer body, a tubular valve core, a mixer connecting pipe connected with the mixer body, and a turbulence body positioned between the mixer body and the mixer connecting pipe. Inflammable gas passes the turbulence body and then enters the mixer connecting pipe to generate an axial rotating and centripetal rotating eddy current, and then the mixing effect of novel air and natural gas is better, so that the working performance and the working safety of an engine are improved, the acceleration performance of the engine is improved, and the fault of fire or backfire of the engine, caused by severely undesirable combustion, can be avoided.

Description

technical field [0001] The invention relates to the field of gas engines, in particular to an engine mixer. Background technique [0002] Gas engines currently on the market mainly use premixed combustion, that is, natural gas and air are mixed outside the engine cylinder to form combustible gas, and finally enter the engine cylinder to perform combustion and work. Since it is a premixed combustion method, there must be a mixer device. There are two main types of mixers at present: one is a Venturi mixer, and the other is a proportional mixer. Venturi mixer installs the spool on the diaphragm, the movement of the diaphragm drives the movement of the spool, and the combustible gas and air are mixed at the valve port of the diaphragm. The proportional mixer adopts a direct mixing method, that is, the natural gas directly enters the mixer body and mixes with air. [0003] The structure of the Venturi mixer is complex, the requirements for processing technology and processing...
