Abstract
The utility model discloses a gas engine mixer. The gas engine mixer is used for a large-displacement gas engine and comprises a mixer body, a tubular valve core and a flow guide groove, wherein natural gas enters an annular natural gas inlet groove and the flow guide groove through a natural gas inlet and is then sprayed into a mixing cavity through a plurality of natural gas inlet holes and a plurality of small holes of the flow guide groove to be mixed with fresh air to form combustible gas; the fresh air enters through an air inlet; and after flowing out of a mixed gas outlet, the combustible gas is subjected to turbulent flow mixing through a turbulent body and then enters a combustion chamber through a mixer connecting pipe to combust to do work. Since the flow guide rove is additionally formed on the tubular valve core of the mixer, the uniformity of mixing of gas and air in case of low speed of a large-displacement gas machine is effectively improved, and the high-flow mixing uniformity during high-speed operation of the engine is also met; and thus, the combustion situation of each station during operation of the engine is improved, and fire or tempering failure of the engine caused by serious poor combustion is avoided.
Description
Technical field
The utility model relates to engine art, particularly a kind of gas engine mixer.
Background technique
Gas engine is in the majority in the application of vehicles such as taxi, public transport at present; But along with the application technology of gas engine is increasingly mature; Its discharge capacity is also increasingly high, and power is increasing, and truck, engineering machinery, peculiar to vessel, generator also begin supporting gas engine.Existing gas engine mainly adopts the premixed combustion mode on the market; Be that rock gas and air mix in the engine air suction tude; Form inflammable gas, get into cylinder at last again and burn, this device that outside engine cylinder, rock gas and air is mixed just is called mixer.Present mixer comprises: mixer body and tubulose spool; Air inlet and the mixed gas outlet that is positioned at the mixing chamber left end that the inner chamber of mixer body is divided into the mixing chamber that is positioned at the middle part and is positioned at the mixing chamber right-hand member; The inwall upper edge of mixing chamber circumferentially offers ring-type rock gas air inlet duct and by the outward extending rock gas suction port of ring-type rock gas air inlet duct; The inner port place of ring-type rock gas air inlet duct offers ring-type spool mounting groove; The sidewall of tubulose spool offers a plurality of rock gas inlet holes, is sleeved in the ring-type spool mounting groove; Rock gas gets into ring-type rock gas air inlet duct through the rock gas suction port; Spurt into mixing chamber through a plurality of rock gas inlet holes again and be mixed into inflammable gas with the fresh air that gets into through air inlet; After inflammable gas is flowed out by mixed gas outlet, take over through mixer again and get into the combustion chambers burn acting.
Because it is bigger to be applied to the air inlet bore of the less discharge capacity gas of suction tude bore machine of big discharge capacity gas machine of truck, engineering machinery, peculiar to vessel, generator; The gas machine is when idling or underrun, and the required gas flow of motor is less, and flow velocity is slower; Gaseous-pressure is also lower; If therefore only simply rely on the circumferential little gas inlet hole of mixer core, dense more the closer to the gas concentration of mixer core wall, and will certainly be low more the closer to mixer core center line gas concentration; This time, the mixed effect of inflammable gas in two zones was bad; Particularly in accelerating process, the concentration of inflammable gas control and unstable, this result directly causes the engine acceleration can be poor; Catastrophe failure such as serious just directly cause engine piston to melt top, engine flashback, catch fire, suction tude bursts influences the Performance And Reliability of motor.
The model utility content
The gas engine mixer that the technical problem that the utility model solves provides and a kind ofly is easy to make, cost is lower, the mixer effect is better, safe and reliable.
For achieving the above object; According to the utility model a kind of gas engine mixer is provided; Be used for big discharge capacity gas engine; Comprise: mixer body, tubulose spool and guiding gutter; Air inlet and the mixed gas outlet that is positioned at the mixing chamber left end that the inner chamber of mixer body is divided into the mixing chamber that is positioned at the middle part and is positioned at the mixing chamber right-hand member, the inwall upper edge of mixing chamber circumferentially offers ring-type rock gas air inlet duct and by the outward extending rock gas suction port of ring-type rock gas air inlet duct, the inner port place of ring-type rock gas air inlet duct offers ring-type spool mounting groove; The tubular valve core retainer plate is contained in the ring-type spool mounting groove, sidewall offer a plurality of rock gas inlet holes and with the guiding gutter mounting hole of rock gas suction port centering; Guiding gutter is a tubulose, and sidewall offers a plurality of apertures; Rock gas gets into ring-type rock gas air inlet duct and guiding gutter through said rock gas suction port; Inject mixing chamber through a plurality of holes in spraying of a plurality of rock gas inlet holes and guiding gutter again and be mixed into inflammable gas with the fresh air that gets into through said air inlet; After inflammable gas is flowed out by mixed gas outlet, get into the combustion chambers burn acting through taking over through mixer again after the mixing of flow-disturbing body flow-disturbing.
Further, the cross section of guiding gutter is the raindrop shape, and major part is towards air inlet during installation, and the microcephaly is towards mixed gas outlet.
Further, a plurality of apertures are along the axially spaced-apart setting of guiding gutter.
Further, the interference of tubulose spool is sleeved in the ring-type spool mounting groove.
Technological scheme according to the utility model; Owing to increase a guiding gutter on the mixer tubulose spool; The uniformity of combustion gas and air mixing when so promptly effectively raising big discharge capacity gas machine low speed; Satisfy the mixture homogeneity of high engine speeds big flow of when operation again, thereby improve the combustion case of each operating mode of engine operation, avoided serious poor combustion and the engine fire or the tempering fault that cause.
