Kodi pali kusiyana kotani pakati pa jekeseni ndi carburetor?

Pali njira zosiyanasiyana zodzaza kuchuluka kwa ntchito zamasilinda a injini yoyaka mkati ndi chosakaniza choyaka. Malinga ndi mfundo ya kusakaniza petulo ndi mpweya, iwo akhoza kugawidwa mu carburetor ndi jekeseni. Pali kusiyana kwakukulu pakati pawo, ngakhale zotsatira za ntchitoyo zimakhala zofanana, koma palinso kusiyana kwakukulu mu kulondola kwa dosing.

Tikambirana mwatsatanetsatane za ubwino ndi kuipa kwa injini ya petulo mphamvu dongosolo m'munsimu.

Mfundo yogwiritsira ntchito injini ya carburetor

Kuti apange zinthu zoyaka mu silinda, petulo iyenera kusakanizidwa ndi mpweya. The zikuchokera mu mlengalenga muli mpweya, amene ndi wofunika kuti makutidwe ndi okosijeni wa mafuta hydrocarbons ndi amasulidwe kuchuluka kwa kutentha.

Mipweya yotentha imakhala ndi voliyumu yokulirapo kuposa kusakaniza koyambirira, komwe kumakonda kukulirakulira, kumawonjezera kukakamiza kwa pisitoni, komwe kumakankhira crankshaft crankshaft ndikupangitsa kuti izungulira. Choncho, mphamvu zamagetsi zamafuta zimasinthidwa kukhala mphamvu zamakina zomwe zimayendetsa galimotoyo.

The carburetor chofunika kuti chabwino atomization wa petulo ndi kusakaniza ndi mpweya kulowa yamphamvu. Nthawi yomweyo, kapangidwe kake kamakhala ndi dosed, chifukwa pakuyatsa kwanthawi zonse ndi kuyaka, ndikofunikira kupanga misa yokhazikika.

Kuti tichite izi, kuwonjezera pa sprayers okha, carburetors ali ndi machitidwe angapo a dosing, omwe ali ndi udindo wina wa ntchito ya injini:

• waukulu mlingo;
• ndondomeko yopanda ntchito;
• chipangizo choyambira chomwe chimalemeretsa kusakaniza pa injini yozizira;
• pampu ya accelerator yomwe imawonjezera mafuta panthawi yothamanga;
• econostat mphamvu modes;
• wowongolera mulingo wokhala ndi chipinda choyandama;
• machitidwe osinthika a multi-chamber carburetors;
• akatswiri azachuma osiyanasiyana omwe amawongolera ndi kuchepetsa mpweya woipa.

Carburetor yomwe imakhala yovuta kwambiri, imakhala ndi machitidwewa, nthawi zambiri amayendetsedwa ndi hydraulically kapena pneumatically, ngakhale m'zaka zaposachedwa, zida zamagetsi zakhala zikugwiritsidwa ntchito.

Koma mfundo yaikulu yasungidwa - emulsion yamafuta yomwe imapangidwa ndi ntchito yolumikizana ya mpweya ndi ma jets amafuta imakokedwa mumayendedwe a mpweya omwe amayamwa ndi ma pistoni kudzera mu ma atomizer molingana ndi lamulo la Bernoulli.

Mawonekedwe a jekeseni

Kusiyana kwakukulu pakati pa jekeseni, kapena ndendende, kachitidwe ka jekeseni wa mafuta, kunali kuperekedwa kwa petulo mopanikizika.

Udindo wa mpope mafuta salinso okha kudzaza zoyandama chipinda, monga izo zinali mu carburetor, koma wakhala maziko a dosing kuchuluka kwa mafuta operekedwa kudzera nozzles kuti zobwezedwa kangapo kapena ngakhale mwachindunji kwa kuyaka zipinda.

Pali makina, zamagetsi ndi osakanikirana jekeseni kachitidwe, koma ali ndi mfundo yofanana - kuchuluka kwa mafuta pa ntchito mkombero masamu ndi mosamalitsa anayeza, ndiko kuti, palibe kugwirizana mwachindunji pakati mlingo otaya mpweya ndi mkombero kumwa mafuta.

Tsopano ma jakisoni amagetsi okha ndi omwe amagwiritsidwa ntchito, pomwe mawerengedwe onse amachitidwa ndi kakompyuta kakang'ono kamene kali ndi masensa angapo ndikuwongolera mosalekeza nthawi ya jakisoni. Kuthamanga kwa pampu kumakhalabe kokhazikika, kotero kuti mapangidwe a osakaniza amadalira mwapadera nthawi yotsegulira ma valve solenoid a jekeseni.

Ubwino wa carburetor

Ubwino wa carburetor ndi kuphweka kwake. Ngakhale mapangidwe akale kwambiri a njinga zamoto ndi magalimoto akale ankagwira ntchito yawo yopatsa mphamvu injini.

Chipinda chokhala ndi choyandama kuti chikhazikitse kupanikizika kwa jet yamafuta, njira ya mpweya ya emulsifier yokhala ndi ndege ya mpweya, atomizer mu diffuser ndipo ndizomwezo. Pamene zofunikira zama injini zidawonjezeka, mapangidwewo adakhala ovuta kwambiri.

Komabe, kuyambika kofunikira kunapereka mwayi wofunikira kotero kuti ma carburetor amasungidwabe m'malo ena, panjinga zamoto zomwezo kapena magalimoto apamsewu. Izi ndi zodalirika komanso zosungika. Palibe chosokoneza pamenepo, kutsekeka kumatha kukhala vuto lokhalo, koma mutha kusokoneza ndikuyeretsa carburetor muzochitika zilizonse, palibe zida zosinthira zomwe zimafunikira.

Ubwino wa jekeseni

Koma zolephera zingapo za ma atomizer oterowo pang'onopang'ono zidapangitsa kuti majekeseni awoneke. Zonsezi zinayamba ndi vuto lomwe limabwera mu ndege, pamene ma carburetors anakana kugwira ntchito mwachizolowezi panthawi ya chisokonezo cha ndege kapena mipukutu yakuya. Kupatula apo, njira yawo yosungira kukakamizidwa kopatsidwa pa jets imachokera ku mphamvu yokoka, ndipo mphamvu iyi nthawi zonse imalunjika pansi. Kuthamanga kwa pampu yamafuta a dongosolo la jekeseni sikudalira malo ozungulira.

Katundu wachiwiri wofunikira wa jekeseni anali wolondola kwambiri wa dosing kapangidwe ka osakaniza mwanjira iliyonse. Carburetor sangathe kuchita izi, ziribe kanthu kuti ndizovuta bwanji, ndipo zofunikira zachilengedwe zimakula chaka chilichonse, chisakanizocho chiyenera kutenthedwa bwino komanso mogwira mtima momwe mungathere, chomwe chinafunikanso ndi mphamvu.

Kulondola kunakhala kofunika kwambiri pakubwera kwa otembenuza othandizira, omwe amawotcha zinthu zovulaza muutsi, pomwe kuwongolera mafuta kwabwino kumabweretsa kulephera kwawo.

Kuvuta kwapamwamba komanso kuchepa kogwirizana ndi kudalirika kwa dongosololi kunathetsedwa ndi kukhazikika ndi kukhazikika kwa zida zamagetsi zomwe zilibe zida zobvala, ndipo matekinoloje amakono amapangitsa kuti apange mapampu odalirika odalirika ndi nozzles.

Momwe mungasiyanitsire galimoto ya jakisoni kuchokera ku carburetor

M'nyumba, munthu amatha kuzindikira nthawi yomweyo kukhalapo kwa chowongolera choyambira cha carburetor, chomwe chimatchedwanso kuyamwa, ngakhale palinso zoyambira pomwe mfundoyi kulibe.

Gawo la jekeseni wa mono ndilosavuta kusokoneza ndi carburetor, amawoneka ofanana kwambiri. Kusiyanitsa ndiko komwe kuli pampu yamafuta, pa carburetor ili pa injini, ndipo pa jekeseni imazimitsidwa mu thanki ya gasi, koma jekeseni imodzi sagwiritsidwanso ntchito.

Jakisoni wamba wamafuta ambiri amatanthauzidwa ndi kusakhalapo kwa gawo lodziwika bwino loperekera mafuta, pali cholandirira mpweya chokha chomwe chimapereka mpweya kuchokera ku fyuluta kupita kumitundu yambiri yolowera, ndipo pamitundu yambiri pali ma nozzles amagetsi, imodzi pa silinda.

Pafupifupi mofananamo, jekeseni wolunjika wamafuta amakonzedwa, kokha pamene ma nozzles ali pamutu wa chipika, monga spark plugs, ndipo mafuta amaperekedwa kudzera pa mpope wowonjezera wothamanga kwambiri. Zofanana kwambiri ndi mphamvu zama injini a dizilo.

Kwa dalaivala, mphamvu ya jakisoni ndiyothandiza mosakayikira. Palibe chifukwa chowonjezera kuwongolera koyambira ndi chopondapo cha gasi, ubongo wamagetsi umayang'anira kusakaniza muzochitika zilizonse ndikuzichita molondola.

Kwa ena onse, kuyanjana kwa chilengedwe kwa jekeseni ndikofunikira, pafupifupi mpweya woipa wa carbon dioxide ndi nthunzi wamadzi umatulutsidwa kuchokera ku utsi kupita ku chilengedwe, kotero kuti carburetors pa magalimoto ndi chinthu chakale.
