Abstract
The present invention provides a twin screw spindle explosion engine which comprises a coaxial integration twin screw spindle compressor separated by burning clapboard, a twin screw spindle expender, a firebox, an ignition mechanism and a screw alveolus exhausted remain exhaust gas. The present invention has merits of simple structure, small volume, calmly operation, high efficiency and easy implement.
Description
Affiliated technical field
The present invention relates to a kind of internal-combustion engine, particularly a kind of double-screw type internal combustion engine.
Background technique:
At present, known motor all is a reciprocating piston type, and the history of the motor of this form is long, and it is abundant to make use experience.But, the deficiency of reciprocating type this machinery: distribution device, vibrations and noise as complex structure, needs complexity are big, two-stroke piston internal-combustion engine as routine, its main shaft revolution four circles have only a commentaries on classics to do manual work, other three commentaries on classics all are consumed works, shortcomings such as therefore it also has change in torque big, and efficient is low.(Jiang Deming chief editor, Principles of Internal-Combustion Engine, Chinese agriculture machinery publishing house, in February, 1981 publish)
Summary of the invention:
Be to overcome the shortcoming of above-mentioned prior art order of the present invention.Propose a kind of rotary type double-screw type internal combustion engine, this machine does not have idle stroke, and each goes to few workmanship twice, does not have complicated distribution device, characteristics such as shockproof, easy to implement.
Technological scheme:
The present invention is made up of dual shaft lever gas compressor, twin-screw expander, firing chamber and cooling and lubrication system, the coaxial composition one of twin-screw gas compressor and twin-screw expander, or by the two independent one of partly forming, there is the cooling channel at the center, front and back two-part are separated the remaining gas spiral alveolar of the row of having between per two teeth groove of the female rotor of twin-screw expander by the firing chamber dividing plate.Combination gas enters the spiral chute of the air-breathing compression chamber of twin-screw gas compressor, enter the firing chamber after the compressed intensification, wait to seal the back and become high-temperature high-pressure fuel gas by the ignition mechanism ignition, promote twin-screw expander with this and do rotation motion, by spindle nose output mechanical work, when decompressor inflationary spiral groove turns over the firing chamber, arrange remaining gas spiral alveolar and firing chamber and connect, firing chamber inner high voltage residual gas is discharged.This moment, a certain amount of lubricant oil entered the spiral chute of the air aspiration cavity of twin-screw gas compressor through intakeport, inflationary spiral groove through the firing chamber from twin-screw expander is discharged, with lubricated each passage of cooling, inflammable mixture and lubricant oil pass through mutually by turns, acting reaches lubricated each passage of cooling by turns, continue acting with this and make engine operation, in whole operation process, cooling liquid from the yin, yang rotor of twin-screw and dividing plate center, firing chamber by cooling off.
The present invention has following effect:
1. because the double-screw type internal combustion machine has a plurality of active chambers on circumference, therefore in changeing, each can repeatedly do work, intake process, expansion acting process and exhaust process are separated from each other, and therefore do not need complicated distribution device, its simple structure, easy to implement, because no reciprocal idle stroke, vibrate for a short time, drag losses is little.
2. because the twin-screw gas compressor is similar and whole coaxial with the twin-screw expander structure, simplify the structure, component are few, make volume little, and the efficient height because of being to rotatablely move, can be realized high speed operation again.
Description of drawings:
(figure middle-jiao yang, function of the spleen and stomach screw rod does not draw, the female screw that only draws, two screw rods only draw partly teeth groove))
Fig. 1 is a structural drawing of the present invention.
Fig. 2 is compression process figure of the present invention.
Fig. 3 is that ignition point combustion gas of the present invention promotes twin-screw expander acting figure.
Fig. 4 is that the present invention discharges remaining waste gas figure.
Among the figure: 1, gas compressor screw rod.2, air-breathing compression chamber.3, cooling channel.4, dividing plate.5, firing chamber.6, ignition mechanism.7, expansive screw.8, expansion chamber.9, residual gas discharge side.
Embodiment:
As Fig. 2, mixed gas enters in the firing chamber 5 of dividing plate 4 through the air-breathing compression chamber 2 of the screw rod 1 of calming the anger, and when compression chamber 2 turned over firing chamber 5, ignition mechanism 6 was lighted mixed gas.As Fig. 3, this moment, the expansion chamber 8 of expansive screw 7 just in time communicated with firing chamber 5, the high pressure-temperature combustion gas enters expansion chamber 8 and promotes expansive screw 7 rotation actings, when expansion chamber 8 left firing chamber 5, residual gas discharge side 9 and firing chamber 5 communicated, and remaining waste gas is discharged, as Fig. 4, after above-mentioned acting process finished, lubricant oil entered firing chamber 5 and discharges from expansion chamber 8 through the chamber 2 of calming the anger, with lubricated each passage.Acting and greasing hocket.
Another mode of execution promptly adds an amount of lubricant oil similar in appearance to two stroke IC engine in fuel oil, in the work by combustion process, greasing can be saved, and compressed mixed gas---is lighted---acting continuously.
Claims (3)
1. double-screw type internal combustion engine.Comprise twin-screw gas compressor, twin-screw expander, firing chamber dividing plate and arrange remaining waste gas spiral alveolar and the ignition mechanism composition, there is cooling passage at its center.It is characterized in that twin-screw gas compressor and twin-screw expander are separated by the firing chamber dividing plate, and whole coaxial.
2. twin-screw explosive motor according to claim 1 is characterized in that twin-screw gas compressor and twin-screw expander be made up of independent two-part.
