Abstract
The utility model discloses a precombustion chamber which comprises an upper body, a middle body and a lower body; the lower end of the upper body is connected with the middle body and the lower body in sequence; a spark plug is mounted on the middle body; a combustion chamber of the precombustion chamber is formed by the middle body and the lower body; and a central through-hole and an auxiliary small hole are formed at the outer end part of the lower body. The precombustion chamber can increase the burning velocity of gas mixture in a main combustion chamber, expand the scope of the air-fuel ratio, reduce the fluctuation of the operating cycle of an internal combustion engine, realize the optimal flame propagation velocity and the optimal penetration distance, increase the burning velocity, shorten the combustion duration, realize the quick burning of rare fuel in the meanwhile, enhance the power performance and the economical efficiency of an engine, and reduce the emission. Furthermore, the precombustion chamber has the advantages of simple structure, convenient assembly and disassembly, low cost and long service life, so as to be widely applied to gas engines.
Description
One, technical field
The utility model relates to the gas engine supporting facility in the field of dynamic engineering, particularly a kind of precombustion chamber.
Two, background technique
At present, gas internal-combustion engine is because output is few, and development difficulty is big, the cost height, and the domestic exploitation that goes in for the study, the producer that makes are few, and it is not wide to explore content, and much that is that all right is ripe for The Application of Technology.
Three, summary of the invention
The purpose of this utility model provides a kind of precombustion chamber, only M30 * 1.5 a hole processing is carried out in former machine cylinder cap bottom, has guaranteed to keep between precombustion chamber lower body and the cylinder cap combining closely.
Precombustion chamber described in the utility model, comprise upper body, intermediate and lower body, the lower end, upper body is connected with lower body with intermediate in turn, and spark plug is installed on the intermediate, intermediate and lower body constitute the firing chamber of precombustion chamber, and described lower body outer end is provided with central through bore and auxiliary aperture.
Wherein, described lower body outer end is the truncated cone body, and its middle part is provided with central through bore, and the circumference conical surface of this central through bore is provided with at least one auxiliary aperture.Described upper body is provided with lower body and is connected trapezoidal thread.
The utility model has following advantage or beneficial effect compared with prior art:
1, the precombustion system is former as the ignition energy amplifier and the disturbance of main combustion chamber, can improve velocity of combustion, shortens combustion duration, has reached the purpose of rare gas fast burn.
2, can obtain power character and improvement discharging preferably.
3, reduce the gentle row's temperature of cylinder, effectively reduced the heat load of component.
4, precombustion chamber is the porous igniting, and it is big to light face, and velocity of combustion is fast, and diffusion is fast, therefore can fully burn, and can not improve power because of incomplete combustion produces pollution, reduces fuel consumption.
5, through verification experimental verification, adopt this precombustion chamber, start easily reliable operation, no carbon distribution, long service life.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, embodiment
Consult accompanying drawing, a kind of precombustion chamber comprises upper body 1, intermediate 2 and lower body 3,1 lower end, upper body is connected with lower body 3 with intermediate 2 in turn, on the intermediate 2 spark plug is installed, intermediate 2 and lower body 3 constitute the firing chamber of precombustion chamber, and lower body 3 outer ends are provided with central through bore 5 and auxiliary aperture 4.
Lower body 3 outer ends are the truncated cone body, and its middle part is provided with central through bore 5, and the circumference conical surface of this central through bore 5 is provided with at least one auxiliary aperture 4.Upper body 1 is provided with lower body 3 and is connected trapezoidal thread.
When the mixed gas in the cylinder is compressed to a certain degree, spark plug is by the mixed gas in the two interelectrode spark ignition precombustion chambers, the gas of burning expands rapidly in precombustion chamber, the channel diameter that is communicated with precombustion chamber and main combustion chamber is less, because throttling action produces pressure difference, make and form turbulent motion in the precombustion chamber, and at full speed in precombustion chamber, spray, the gas band of burning flame and rapidly the mixed gas in the main combustion chamber is almost lighted simultaneously, in main combustion chamber, produce strong burning and hold together the stream motion, make the rapid combustion in main combustion chamber of most of mixed gas.Here it is the said flame ignition mixed gas in front, rather than usually said spark ignition.
The ready-made merit of the utility model is tried out on my company 190 serial low concentration gas mechanisms of qi, and obtains good result.
Claims (3)
1, a kind of precombustion chamber, comprise upper body, intermediate and lower body, it is characterized in that the lower end, upper body is connected with lower body with intermediate in turn, installs spark plug on the intermediate, intermediate and lower body constitute the firing chamber of precombustion chamber, and described lower body outer end is provided with central through bore and auxiliary aperture.
2, precombustion chamber according to claim 1 is characterized in that described lower body outer end is the truncated cone body, and its middle part is provided with central through bore, and the circumference conical surface of this central through bore is provided with at least one auxiliary aperture.
