Problems solved by technology

If the mixing quality of gas and air is poor, it will inevitably lead to different proportions of gas in each cylinder, which will lead to poor work consistency of each cylinder, and also cause abnormal combustion in the engine cylinder; these possible problems will affect the power and economy of the engine. , emissions and durability have significant and adverse effects
[0003] The existing gas mixer of the gas engine has an unreasonable gas outlet structure and layout, which easily leads to the problem of poor mixing effect of gas and air

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] A gas mixer for an engine of the present invention comprises a mixing tube 1, which is radially inserted into the intake manifold 2 of the engine, and a plurality of gas nozzles 11 are opened on the wall of the mixing tube 1, and the gas The nozzle 11 is in the shape of a bar extending along the axial direction of the mixing tube 1 .

[0031] Specifically, as shown in the attached figure 1 , the axial direction of the mixing tube 1 is perpendicular to the axial direction of the intake manifold 2, and the gas nozzle 11 is arranged as a strip extending along the axial direction of the mixing tube 1, so that the gas ejected from the gas nozzle 11 forms a shape along the axis of the mixing tube 1. The wind wall extending in the direction, and the flow direction of the air is along the axis of the intake manifold 2, so the air directly contacts the wall surface of the wi...

Abstract

The invention provides a fuel gas mixer of an engine. The fuel gas mixer comprises a mixing pipe, the mixing pipe is inserted into an intake manifold of the engine along the radial direction, a plurality of fuel gas nozzles are arranged on the pipe wall of the mixing pipe, and the fuel gas nozzles are strip-shaped and extend along the axis direction of the mixing pipe. According to the fuel gas mixer, the strip-shaped gas nozzle is adopted to replace an existing round-hole-shaped gas nozzle, on the basis that the flow area of the gas nozzle is fixed, the mixing contact area of gas and air is greatly increased, the mixing effect of two kinds of gas can be improved, and high-quality mixed gas can be obtained; and normal operation of the gas engine is facilitated, and various performances are ensured.

Description

technical field [0001] The invention relates to the technical field of gas engines, in particular to a gas mixer for the engine. Background technique [0002] A gas engine is an engine that uses natural gas as fuel. The gas mixer is an important part of the gas engine gas system. It is used to mix gas fuel with air. The rationality of its structure will directly affect the mixing effect of gas and air. . If the mixing quality of gas and air is poor, it will inevitably lead to different proportions of gas in each cylinder, which will lead to poor work consistency of each cylinder, and also cause abnormal combustion in the engine cylinder; these possible problems will affect the power and economy of the engine. , emissions and durability all have significant and adverse effects. [0003] The existing gas mixer of the gas engine has an unreasonable gas outlet structure and layout, which easily leads to the problem of poor mixing effect of gas and air. Contents of the invent...
