Description
Išradimas priklauso vidaus degimo varikliams su rotoriais, tarpusavyje sąveikaujančiais jų šoninio paviršiaus įdubomis ir iškylomis ir jų dėka sudarančiais kintamo tūrio darbo ertmes.BACKGROUND OF THE INVENTION The invention relates to internal combustion engines with rotors that interact with their side surface recesses and recesses and thereby form variable volume work cavities.
Yra žinomas rotorinis vidaus degimo variklis, kuriame yra korpusas su dviem lygiagrečiomis susikertančiomis cilindrinėmis ertmėmis, kuriose ant lygiagrečių velenų, sujungtų sinchronizuojančia krumpliaratine pavara, yra rotorius su įdubomis ir rotorius su iškylomis; įdubų skaičius yra didesnis negu iškylų, rotorių matmuo ašies kryptimi L=0,75 -1,5 rotoriaus apskritimo stygos, apibrėžiančios įdubos plotį, o iškylos plotį nusakanti rotoriaus stygaThere is known a rotary internal combustion engine having a casing with two parallel intersecting cylindrical cavities which, on parallel shafts connected by a synchronous gear drive, have a recess rotor and a pitch rotor; the number of recesses is larger than that of the picnic, the rotor dimension in the axial direction L = 0.75 -1.5 rotor circular string defining the recess width and the picnic width rotor string
1θ CR=0,33-0,55 atstumo tarp rotorių centrų. Įdubose (arba ant iškylų) yra numatytos uždegimo žvakės (SSRS pat.Nr.565635, TPK F02B55/00, publ. 1977,07.15).1θ C R = 0.33-0.55 distance between rotor centers. The recesses (or picnic areas) are provided with spark plugs (USSR Pat. No. 565635, TPK F02B55 / 00, Publ. 1977.07.15).
Šio rotorinio vidaus degimo variklio trūkumas yra tai, kad jame nėra atsižvelgta, kad prie to paties rotorių diametro jo sąlygojamas mažesnis įdubų skaičius gali paduoti į degimo kamerą daugiau degimo mišinio negu didesnis mažesnių įdubų skaičius. Taigi, turint didesnes įdubas prie tų pačių variklio gabaritų galima gauti didesnį galingumą. Trūkumas yra ir tai, kad kiekvienoje įduboje vykdant mišinio uždegimą komplikuojasi uždegimo sistema, kadangi reikia realizuoti besisukančių paviršių elektrinį kontaktą. Šio 20 trūkumo išvengia vidaus degimo variklis pagal paraišką Nr. WO 91/10052, TPK F02B53/08, publ. 1991.07.11, kuriame degimo kamera yra korpuse tarp kompresoriaus ir ekspanderio rotorių. Tačiau variklio apimtis padidėja daugiau negu dvigubai, nes įvesto ekspanderio rotorių matmuo ašies kryptimi didesnis negu kompresoriuje.The disadvantage of this rotary internal combustion engine is that it does not take into account the fact that the smaller number of recesses due to the same rotor diameter can bring more combustion mixture into the combustion chamber than the larger number of smaller recesses. Thus, larger recesses at the same engine gauge allow for greater power output. Another disadvantage is that the ignition system is complicated by the ignition of the mixture in each recess, since the electrical contact of the rotating surfaces has to be realized. This drawback 20 is avoided by the internal combustion engine according to application no. WO 91/10052, TPK F02B53 / 08, Publ. 11.07.1991, in which the combustion chamber is housed between a compressor and an expander rotor. However, the engine volume is more than doubled because the introduced expander rotors have a larger axial dimension than the compressor.
25 Išradimo prototipu yra variklis pagal SSRS pat. Nr.565635. 25 Preferably, the engine according to the USSR. No.565635.
Prototipo trūkumai pašalinami tuo, kad rotoriniame vidaus degimo variklyje, kuriame yra korpusas su dviem lygiagrečiomis cilindrinėmis susikertančiomis ertmėmis, kuriose yra du lygiagretūs velenai, surišti sinchronizuojančia krumpliaratine pavara, ant kurių sumontuoti rotoriai, sujungti savo šoninio paviršiaus įdubomis ir iškylomis, pagal išradimą vienas rotorius turi dvi įdubas, o kitas vieną iškylą.The disadvantages of the prototype are eliminated by the fact that a rotary internal combustion engine having a housing with two parallel cylindrical intersecting cavities with two parallel shafts connected by a synchronous gear, mounted on rotors, has its side surface recesses and protrusions, according to the invention. two recesses and one picnic.
Pagal išradimą uždegimo žvakė numatyta korpuse ir uždegimo metu yra už įdubos ribų.According to the invention, the spark plug is provided in the housing and is located outside the recess at the time of ignition.
Variklis gali turėti ne vieną rotorių porą su skirtinga iškylos padėtimi veleno apskritimo atžvilgiu.The engine may have a plurality of rotor pairs with different pitch positions relative to the shaft circumference.
Variklyje rotorius su įdubomis, gali sąveikauti su dviejų rotorių iškylomis, esančių ant velenų, lygiagrečių rotoriaus su įdubomis velenui.In the engine, the rotor with recesses can interact with the two rotor bumps on the shafts parallel to the shaft of the rotor with recesses.

Variklis turi korpusą 1 su susikertančiomis cilindrinėmis ertmėmis 2 ir 3, kuriose yra rotorius 4 su dvejomis įdubomis ir rotorius 5 su viena iškyla (fig.1). Rotoriai sumontuoti ant lygiagrečių velenų 6 ir 7, sujungtų sinchronizuojančia krumpliaratine pavara 8, užtikrinančia rotorių 4 ir 5 greičių santykį i=1:2. Korpuse 1 yra įmontuota uždegimo žvakė 9 ir prapūtimo bei kuro padavimo kanalai 10 ir 11.The motor has a housing 1 with intersecting cylindrical cavities 2 and 3, comprising a rotor 4 with two recesses and a rotor 5 with one protrusion (Fig. 1). The rotors are mounted on parallel shafts 6 and 7 connected by synchronous gear 8, which provides a ratio of rotors 4 and 5 of speed i = 1: 2. Housing 1 includes a spark plug 9 and purge and fuel supply passages 10 and 11.
Rotoriaus 4 spindulys lygus cilindrinių ertmių spinduliui R (fig.1,7). Rotoriaus įdubų paviršiaus kreivumo spindulys yra artimas spinduliui R. Rotoriaus 5 iškilusios dalies kreivumo spindulys lygus R, toliau eina paviršius su kintamu kreivumo spinduliu p, pereinantis į paviršių su kreivumo spinduliu p =A-R, kur A yra atstumas tarp rotorių ašių. Rotorius 5 yra simetriškas savo išilginės ašies atžvilgiu, todėl pakanka nustatyti vienos rotoriaus pusės kontaktavimo paviršių. Kai rotoriai 4 ir 5 yra padėtyje pagal fig.1,7 tai variklio darbo ertmė yra minimali. Išeinant iš šios pilno kontakto padėties ir į ją ateinant turi būti užtikrintas rotoriaus5 hermetinis kontaktas su įdubos briauna, kurį slenka pagal apskritimo liniją 00' (fig.7) su spinduliu R. Kontaktavimo pradžioje tokį spindulį turi ir rotoriaus 5 kontaktuojantis paviršius. Šio spindulio padėtį nusako kampas βρι tarp jo ir rotorių centrus jungiančios linijos OiO2. Tokio pat dydžio yra ir analogiškas rotoriaus 4 kampas ocr=Pr.The radius of the rotor 4 is equal to the radius R of the cylindrical cavities (Fig. 1.7). The radius of curvature of the surface of the rotor recesses is close to the radius R. The radius of curvature of the protruding part of the rotor 5 is equal to R, followed by a surface with variable radius of curvature p passing to the surface with radius of curvature p = AR. The rotor 5 is symmetrical with respect to its longitudinal axis, so it is sufficient to determine the contact surface of one side of the rotor. When the rotors 4 and 5 are in position according to Fig. 1.7, the engine working cavity is minimal. Leaving this full contact position and entering it must be ensured that the rotor 5 is hermetically sealed with a recess which slides along the circumference 00 '(Fig.7) with a radius R. At the beginning of the contact, such a radius also has the contact surface of the rotor 5. The position of this beam is defined by the angle βρι between it and the line OiO 2 connecting the rotor centers. An analogous rotor angle 4 ocr = Pr is the same size.
Kampams a ir β mažėjant, rotoriaus 4 spindulys nesikeičia, o rotoriaus 5 spindulys kontakto padėtyje keičiasi nuo p=R iki p=A-R (fig.7). Iš fig.7 matyti, kad kiekvienam kampui oų atitinka tam tikro ilgio p, ir jo padėtį nusakantis kampas βμ Rotorius 4 ateidamas į padėtį a, padaro kampą Aa=aR-aį.As the angles a and β decrease, the radius of the rotor 4 does not change and the radius of the rotor 5 at the contact position changes from p = R to p = AR (Fig.7). It can be seen from Fig. 7 that for each angle o o corresponds to a certain length p, and its position defining angle βμ Rotor 4, when coming to position a, makes an angle Aa = a R a .
Rotorius 5 į kontakto padėtį ateina padaręs kampą 2Δα, nes jis sukasi dvigubai didesniu greičiu. Todėl nuo kampo βι prieš sukimosi kryptį atidėję kampą 2Δα turėsime pį padėtį ant rotoriaus 5 paviršiaus, iš kurios jis ateina į kontakto padėtį, apibrėžtą kampais oc, ir βμ Atidėjus kampą 2aR nuo linijosRotor 5 comes into contact position at an angle of 2Δα because it rotates at twice the speed. Therefore, by deflecting angle 2Δα from the angle βι in the direction of rotation, we will have pis position on the surface of the rotor 5 from which it comes to the contact position defined by angles oc and βμ Subtracting angle 2a R from the line
OiO2 (a =0, β=0) gauname rotoriaus 5 paviršių su pastoviu kreivumo spinduliu p=A-R. Rotoriaus 5 gamybai patogiau yra turėti kintamo kreivumo paviršiaus skaičiavimo formules. Polinėje koordinačių sistemoje radiusą vektorių p ir poliarinį kampą <p galima išreikšti sekančiai:For OiO 2 (a = 0, β = 0) we obtain the surface of the rotor 5 with a constant radius of curvature p = AR. For the production of rotor 5, it is more convenient to have a formula for calculating a variable curvature surface. The vector p and the polar angle <p found in the polar coordinate system can be expressed as follows:
Pi = 7A2 +R2 -2ARcosai <PrPR-(2aR-P.) βΗ =arctgV(2R/A)2 -1 = arctg sincųPi = 7A 2 + R 2 -2ARcosai <PrP R - ( 2a RP.) Β Η = arctgV (2R / A) 2 -1 = arctg sync
A/R-cosciiA / R-coscii
Rotorinis vidaus degimo variklis veikia sekančia tvarka. Rotoriams 4 ir 5 25 pajudėjus iš pilno kontakto padėties, suspaustas oro ir kuro mišinys uždegamas žvakės 9 kibirkštimi. Sudegusio kuro šiluma pakelia darbo agento slėgį ir rotoriai jo veikiami velenams 6 ir 7 atiduoda mechaninį darbą.The rotary internal combustion engine operates in the following order. When rotors 4 and 5 25 move from full contact position, the compressed air / fuel mixture is ignited by spark 9 spark. The heat of the burned fuel raises the pressure of the working agent and the rotors impart mechanical action to the shafts 6 and 7.
Darbo agentui išsiplėtus, per kanalus 10 ir 11 paduodamas prapūtimo oras. Degimo produktus pašalinus, oro padavimas nutraukiamas, o į darbo ertmėje esantį orą išpurškiama kuro porcija ir gautas mišinys besisukančių rotorių 4 ir 5 paviršiais paduodamas į suspaudimo kamerą 12.As the labor agent expands, purge air is supplied through ducts 10 and 11. After removal of the combustion products, the air supply is interrupted and a portion of the fuel is sprayed into the air in the working cavity and the resulting mixture is fed to the compression chamber 12 on the surfaces of rotating rotors 4 and 5.
Toliau variklio darbo ciklas kartojasi. Jei karbiuratoriniam varikliui suspaudimo laipsnis pilno kontakto padėtyje yra per didelis, jį galima sumažinti pagilinant įdubą arba iškyloje padarant įdubimą.The engine cycle continues to repeat. If the compression ratio of the carburetor motor at full contact position is too high, it can be reduced by deepening the recess or by making a recess in the picnic.
Dyzelinio variklio atveju vietoje uždegimo žvakės numatytas kuro purkštukas kuris paduoda kurą į suspaustą įkaitusį orą, kurio aukštos temperatūros dėka įvyksta savaiminis užsiliepsnojimas.In the case of a diesel engine, instead of a spark plug, a fuel injector is provided which feeds the fuel into compressed hot air, which, due to its high temperature, spontaneously ignites.
Rotorinių vidaus degimo variklių galingumo rodikliu gali būti rotoriaus iškylos plotį nusakančios stygos santykis su atstumu tarp rotorių ašių. Prototipe jis nurodytas kaip Cr=0,33-0,55. Pateikiamame variklyje šis santykis artėja prie 1. Variklio galingumas gali būti padidinamas, ant tų pačių velenų sumontuojant kelias rotorių poras. Kadangi rotorius, turintis tik vieną iškylą, reikalauja išcentravimo priemonių, tai kelių rotorių atitinkamas išdėstymas ant vieno veleno kaip tai parodyta fig.5 palengvina šio uždavinio sprendimą. Variklio galingumą taip pat galima padidinti, sukomplektuojant vieną rotorių su įdubomis su dviem rotoriais, turinčiais iškylas (fig.6).The power index of rotor internal combustion engines may be the ratio of the stroke width of the rotor to the distance between the rotor axes. In the prototype it is specified as Cr = 0.33-0.55. In the present engine this ratio approaches 1. The power of the engine can be increased by installing several pairs of rotors on the same shafts. Since the rotor having only one protrusion requires centering means, the corresponding arrangement of several rotors on one shaft as shown in Fig. 5 facilitates the solution of this problem. The power of the motor can also be increased by completing a single rotor with recesses with two rotors having protrusions (Fig. 6).
