Kodi octane nambala mafuta?

Dalaivala akalowa m'malo ogulitsira mafuta, amaimika galimoto yake pamalo enaake, zomwe zikuwonetsa mafuta omwe angathe kuthiridwa mafuta pamalo ano. Kuphatikiza pa kuti mwiniwake wa galimoto ayenera kusiyanitsa pakati pa mafuta (mafuta, mafuta kapena dizilo), mafuta ali ndi mitundu ingapo, potchulapo nambala inayake.

Manambalawa akuimira kuchuluka kwa mafuta mumafuta. Kuti mumvetse kuopsa kwa kugwiritsa ntchito mafuta osayenerera galimoto, muyenera kudziwa kuti pali kusiyana kotani pakati pamtunduwu, ndi zinthu ziti zomwe zimakhudzidwa ndi RH komanso ngati zingayesedwe pawokha.

Nambala ya octane ndi chiyani

Musanamvetsetse matchulidwe, muyenera kukumbukira kuti injini yamafuta imagwira ntchito yanji (mwatsatanetsatane wamafuta oyaka mkati werengani apa). Mafuta osakanikirana ndi mafuta amaphatikizidwa mu silinda, pomwe amapanikizidwa ndi pisitoni kangapo (mu mitundu yokhala ndi jekeseni wachindunji, mpweya umakanikizidwa, ndipo mafuta amapopedwa nthawi yomweyo chisanachitike).

Pamapeto pa kupsinjika, BTC imayatsidwa ndi mphamvu yayikulu yopangidwa ndi pulogalamu yoyatsira, yomwe ndi mapulagi. Kutentha kwa chisakanizo cha mpweya ndi mafuta kumachitika mwadzidzidzi, chifukwa cha mphamvu yabwino yomwe imatulutsidwa, kukankhira pisitoniyo moyang'anizana ndi ma valve.

Tikudziwa kuchokera kumaphunziro a fizikiya kuti mukapanikizika kwambiri, mpweya umatentha. Ngati BTC imapanikizika muzipilala kuposa momwe ziyenera kukhalira, chisakanizocho chimangoyaka zokha. Ndipo nthawi zambiri izi sizimachitika pisitoni ikamenya sitiroko yoyenera. Izi zimatchedwa detonation ya injini.

Ngati njirayi imawonekera nthawi zambiri pamene injini ikugwira ntchito, idzalephera msanga, chifukwa nthawi zambiri kuphulika kwa VTS kumachitika panthawi yomwe pisitoni imayamba kupondereza kaphatikizidwe kapena sinamalize sitiroko. Pakadali pano, KShM ili ndi vuto lapadera.

Kuti athetse vutoli, opanga magalimoto amakono akukonzekeretsa injini ndi masensa omwe amamva kugogoda. Makina oyang'anira zamagetsi amasintha magwiridwe antchito amafuta kuti athetse izi. Ngati sichingachotsedwe, ECU imangoyimitsa injini ndikulepheretsa kuti iyambe.

Koma nthawi zambiri vutoli limathetsedwa posankha mafuta oyenera - ndiye kuti, ndi muyeso wa octane woyenera mtundu wa injini yoyaka mkati. Chiwerengero cha dzina la mafuta chimasonyeza kuchepa kwa msakanizo komwe chisakanizo chimadzipangira chokha. Kuchuluka kwa chiwerengerocho, ndipamene mafuta amaponderezedwa kwambiri asanadziyese.

Phindu lenileni la nambala ya octane

Pali mitundu yosiyanasiyana yamagetsi. Amapanga zovuta zosiyanasiyana kapena kuponderezana muzitsulo. Pomwe BTC imafinya kwambiri, mphamvu yamagalimoto imatulutsa mphamvu zambiri. Mafuta ochepa a octane amagwiritsidwa ntchito pamagalimoto otsika kwambiri.

Nthawi zambiri ndimakhala magalimoto akale. M'mitundu yamakono, makina oyendetsa bwino amakhazikitsidwa, omwe amakhalanso oyenera chifukwa chothina kwambiri. Amagwiritsa ntchito mafuta okwera kwambiri. Kufunika kodzaza thanki osati ndi 92, koma mafuta a 95 kapena 98 amapezeka muzolemba zamagalimoto.

Ndi zisonyezo ziti zomwe zimakhudza nambala ya octane

Mafuta ndi dizilo akapangidwa, mafutawo amagawika m'magawo ang'onoang'ono. Pakukonza (kusefera ndi kugawanika), mafuta oyera amapezeka. RH yake imagwirizana ndi 60.

Kuti mafuta agwiritsidwe ntchito mu injini zoyaka zamkati, popanda kuphulika komwe kumachitika muzipilala, zowonjezera zowonjezera zimawonjezeredwa pamadzi panthawi yopukutira.

RON ya mafuta imakhudzidwa ndi kuchuluka kwa ma hydrocarbon omwe amakhala ngati anti-knock (monga mu RON yowonjezera zowonjezera zomwe zimagulitsidwa m'malo ogulitsa magalimoto).

Njira zodziwira nambala ya octane

Kuti mudziwe madigirii a mafuta omwe angagwiritse ntchito m'galimoto yawo yokhala ndi injini inayake, wopanga amayesa ndi mafuta. Injini yoyaka yamkati mkati imayikidwa pachitetezo. Palibe chifukwa chokwanitsira injini yonse, chokwanira chimodzi chokha chofanana ndi magawo ofanana ndi chokwanira.

Akatswiri amagwiritsa ntchito zochitika zosiyanasiyana kuti adziwe nthawi yomwe kuphulika kumachitika. Magawo a kutentha kwa VTS, kukakamiza kwamphamvu ndi magawo ena omwe mafuta amasintha mosadukiza. Kutengera izi, zimatsimikizika kuti mafuta amayenera kuyendera mafuta ati.

Njira yoyezera Octane

Ndizosatheka kupanga muyeso wotere kunyumba. Pali chida chomwe chimatsimikizira kuchuluka kwa octane nambala ya mafuta. Koma njirayi sigwiritsidwa ntchito kawirikawiri ndi malo opangira ma labotale omwe amawunika mtundu wamafuta omwe amagulitsidwa mdziko muno, chifukwa ili ndi vuto lalikulu.

Pofuna kudziwa molondola RON wamafuta, opanga mafuta amagwiritsa ntchito njira ziwiri m'malo a labotale:

1. Mafuta osakaniza a mpweya amatenthedwa mpaka madigiri 150. Amadyetsedwa mu mota, liwiro lomwe limakhazikika pa 900 rpm. Njirayi imagwiritsidwa ntchito kuyesa mafuta ochepa a octane;
2. Njira yachiwiri siyikupereka mwayi wokonzeratu HTS. Amayendetsa galimoto, yomwe imathamanga pa 600 rpm. Njirayi imagwiritsidwa ntchito kuyesa kutsata mafuta, kuchuluka kwa octane kupitilira 92.

Zida zoyezera

Inde, njira zothetsera mafuta sizipezeka kwa oyendetsa galimoto wamba, kotero ayenera kukhala wokhutira ndi chida chapadera - mita ya octane. Nthawi zambiri, amagwiritsidwa ntchito ndi omwe amakhala ndi magalimoto omwe amasankha malo ama gasi kuti akonde, koma kuti asayese magetsi okwera mtengo m'galimoto.

Zomwe zimapangitsa kuti anthu asamakhulupirire izi ndi kusakhulupirika kwa ogulitsa omwe amagwiritsa ntchito mafuta otsika kapena osungunuka kuti apindule.

Chipangizocho chimagwiritsa ntchito mphamvu ya dielectric ya mafuta. Ndikokwera kwambiri, kuchuluka kwa octane kudzawonetsedwa ndi chipangizocho. Kuti mudziwe magawowo, mufunika gawo loyang'anira mafuta oyera omwe ali ndi nambala ya octane. Choyamba, chipangizocho chimapangidwa, kenako mafuta omwe amachokera podzazidwa amafanizidwa ndi mtunduwo.

Komabe, njirayi ili ndi zovuta zina. Chipangizocho chiyenera kuwerengedwa. Pachifukwa ichi, n-heptane imagwiritsidwa ntchito (RON ndi zero), kapena mafuta okhala ndi nambala yodziwika kale ya octane. Zina zimakhudzanso kulondola kwa muyeso.

Zina mwazida zodziwika bwino za njirayi ndi OKTIS yaku Russia. Zodalirika kwambiri komanso zolondola pamiyeso - analogue yachilendo ya Digatron.

Momwe mungakulitsire octane nambala yamafuta

Mutha kuonjezera octane nambala ya mafuta nokha ngati mutagula zowonjezera zopangira izi. Chitsanzo cha chida chotere ndi Lavr Next Octane Plus. Thunthu udzathiridwa mu thanki mpweya pambuyo mafuta. Imasungunuka mwachangu mu mafuta. Malinga ndi kuyeza kwina, wothandizirayo amachulukitsa nambala ya octane kukhala mayunitsi sikisi. Malinga ndi wopanga, ngati galimoto ikuyenera kuthamanga pa mafuta a 98, ndiye kuti dalaivala amatha kudzaza zowonjezera za 92 ndikutsanulira zowonjezera izi mu thanki.

Zina mwazofanana, zomwe ndizochepa pang'ono, komanso zimawonjezera mafupipafupi:

• Astrohim Octane + (mayunitsi 3-5);
• Octane + wolemba Octane Plus (kuwonjezeka ndi magawo awiri);
• Liqui Moly Octane + (mpaka mayunitsi asanu).

Chifukwa chomwe eni magalimoto ambiri amagwiritsa ntchito mafuta a 92 pazowonjezera m'malo mwa 95 kapena 98 ndi chikhulupiriro chofala (nthawi zina sichopanda maziko) kuti eni malo ogulitsira mafuta amagwiritsa ntchito njirayi.

Nthawi zambiri, zinthu zomwe zimachepetsa mwayi wophulika msanga zimagwiritsidwa ntchito kukulitsa kukana kuphulika msanga. Chitsanzo cha izi ndi mayankho omwe ali ndi mowa kapena tetraethyl lead. Ngati mugwiritsa ntchito chinthu chachiwiri, ndiye kuti ma kaboni amadzipangira pisitoni ndi ma valve.

Kugwiritsa ntchito mowa (ethyl kapena methyl) kumakhala ndi zovuta zochepa. Amadzipukuta kuchoka pagawo limodzi la mankhwala mpaka magawo 10 a mafuta. Monga momwe iwo amagwiritsira ntchito njirayi akutsimikizira, mpweya wotulutsa utsi wagalimoto umatsuka komanso kuphulika sikuwonedwa. Komabe, ziyenera kukumbukiridwa kuti mowa umakhalanso ndi "mbali yakuda" - ndiwosakanikirana, ndiye kuti, umatha kuyamwa chinyezi. Chifukwa cha ichi, mu thanki komanso mafuta, mafuta azikhala ndi chinyezi chochulukirapo, chomwe chingasokoneze magwiridwe antchito a injini.

Kuti mumve zambiri pazowonjezera zamtunduwu, onani vidiyo iyi:

Zowonjezera za mafuta (mafuta) - KODI MUKUFUNA? VERSION YANGA

Momwe mungachepetse nambala ya octane

Ngakhale magalimoto amakono adapangidwa kuti azitha kuyendetsa mafuta okwera kwambiri, palinso magalimoto ambiri omwe injini zawo zimagwiritsa ntchito 80 ndipo nthawi zina ngakhale zopangira 76 zamafuta. Ndipo izi sizikugwira ntchito pamagalimoto akale okha, komanso magalimoto ena amakono, mwachitsanzo, thalakitala zoyenda kumbuyo kapena zida zapadera (ma jenereta amagetsi).

Pamalo wamba amafuta, mafuta oterewa sanagulitsidwe kwa nthawi yayitali, chifukwa siopindulitsa. Pofuna kuti asasinthe njirayi, eni ake amagwiritsa ntchito njira yochepetsera nambala ya octane, chifukwa magwiridwe antchito a injini amasinthidwa kukhala machitidwe a mafuta a 92. Nazi njira zina:

1. Anthu ena amasiya kachitini ka mafuta katseguka kwakanthawi. Ngakhale ili lotseguka, zowonjezera zimaphwera mu mafuta. Zimavomerezedwa kuti HR imachepa ndi theka tsiku lililonse. Mawerengedwe akuwonetsa kuti zitenga pafupifupi milungu iwiri kuti musinthe kuchokera pa 92 mpaka pa 80. Zachidziwikire, pankhaniyi, muyenera kukhala okonzeka kuti voliyumu yamafuta ichepetsedwa kwambiri;
2. Kusakaniza mafuta ndi palafini. M'mbuyomu, oyendetsa galimoto anali kugwiritsa ntchito njirayi, popeza palibe chifukwa chowonongera ndalama zomwe analipira. Vuto lokhalo ndiloti ndizovuta kusankha gawo loyenera.

Ndi chiwonongeko chowopsa bwanji

Kugwiritsa ntchito mafuta otsika-octeni mu injini, zolemba zawo zomwe zimawonetsa mtundu wina wamafuta, zitha kubweretsa kuphulika. Popeza pisitoni ndi chopukutira chimayang'anizana ndi katundu wambiri, zachilengedwe za sitiroko inayake, mavuto otsatirawa akhoza kuwoneka ndi mota:

• Kutentha kwa ma valve;
• Kufooka ndi mapindikidwe mapisitoni;
• Kusintha kwa ndodo zolumikizira;
• Kutenthedwa kwa mota ndi zotsatira zoyipa zomwe zimakhudzana.

Izi ndi zina mwazifukwa zomwe injini sayenera kuyendetsedwa ndi mafuta ochepa a octane.

Pomaliza - kanema wina woperekedwa ku detonation:

Kugogoda - MMENE MUNGADZIWIRE NDI KUTETEZA MOTO

Mafunso ndi Mayankho:

Ndi mafuta ati omwe ali ndi octane wapamwamba kwambiri? Makamaka magalimoto amasewera amawotchedwa ndi mafuta otere. Mafuta otsogolera ndi octane apamwamba kwambiri (140). Chotsatira chimabwera chopanda kutsogolo - 109.

Kodi nambala ya octane ya petulo 92 imatanthauza chiyani? Uku ndiye kukana kwamafuta amafuta (pamene kutentha kwake kumayaka zokha). OCH 92 kapena zina zimakhazikitsidwa pansi pa zochitika za labotale.

Momwe mungadziwire nambala ya octane yamafuta? M'malo a labotale, izi zimachitika pogwiritsa ntchito 1-cylinder motor. Ntchito yake pa petulo ikufanizidwa ndi kusakaniza kwa isooctane ndi N-heptane.
