Injini yama stroke awiri mgalimoto

Dziko lamagalimoto lakhala likuwona zochitika zambiri zamagetsi. Ena mwa iwo adakhala oundana munthawi yake chifukwa choti wopanga analibe njira zopititsira patsogolo ubongo wake. Zina zidakhala zopanda ntchito, chifukwa chake izi sizinakhale ndi tsogolo labwino.

Kuphatikiza pa mainline oyambira kapena makina ooneka ngati V, opanga amapanganso magalimoto okhala ndi zida zina zamagetsi. Pansi pa mitundu yazithunzi zina amatha kuwona Injini ya Wankel, nkhonya (kapena nkhonya), haidrojeni galimoto. Ena opanga makina atha kugwiritsabe ntchito ma powertrains osowa pamitundu yawo. Kuphatikiza pa zosinthazi, mbiri imadziwa ma motors angapo osachita bwino (ena a iwo ndi omwe nkhani yosiyana).

Tsopano tiyeni tikambirane za injini yotere, yomwe pafupifupi pafupifupi onse oyendetsa galimotoyo sanakumane nayo, ngati ayi kuti ndiyankhule zakufunika kochekera udzu ndi makina otchetchera kapinga kapena kudula mtengo wokhala ndi zingwe. Izi ndizigawo ziwiri zamagetsi. Kwenikweni, injini zamtundu woyaka zamtunduwu zimagwiritsidwa ntchito pamagalimoto, m'matangi, ndege za pistoni, ndi zina zambiri, koma makamaka mgalimoto.

Komanso, injini zama stroke ndizotchuka kwambiri mu motorsport, popeza mayunitsiwa ali ndi zabwino zambiri. Choyamba, ali ndi mphamvu zazikulu zosunthira pang'ono. Kachiwiri, ma mota awa ndiopepuka chifukwa cha kapangidwe kake kosavuta. Izi ndizofunikira kwambiri pamasewera othamangitsa awiri.

Ganizirani za zida za zosinthazi, komanso ngati zingagwiritsidwe ntchito mgalimoto.

Kodi injini yama stroke ndi chiyani?

Kwa nthawi yoyamba, patent yopanga ma injini oyaka mkati mwazaka zoyambirira za 1880. Kukula kumeneku kunaperekedwa ndi injiniya Douglad Clerk. Zipangizo za brainchild yake zinali zonenepa ziwiri. Wina anali wogwira ntchito, ndipo winayo anali kugwira ntchito zatsopano zankhondo.

Patatha zaka 10, kusinthidwa ndi chipinda blowdown, amene analibenso pisitoni kumaliseche. Galimoto iyi idapangidwa ndi Joseph Day.

Mofananamo ndi izi, Karl Benz adapanga gasi yake, patent yopanga yomwe idachitika mu 1880.

Dvigun ya sitiroko iwiri, monga dzina lake limatanthawuzira, mu crankshaft imodzi imagwira zikwapu zonse zofunika kuti pakhale mafuta oyaka komanso kuyatsa kwa mafuta, komanso kuchotsa zinthu zoyaka m'galimoto . Kuthekera kumeneku kumaperekedwa ndi kapangidwe kake ka chipindacho.

Mu pisitoni kamodzi pisitoni, zikwapu ziwiri zimachitidwa mu silinda:

1. Pisitoniyo ali pansi pakufa, yamphamvu imatsukidwa, ndiye kuti, zinthu zoyaka zimachotsedwa. Sitiroko imaperekedwa chifukwa chodya gawo latsopano la BTC, lomwe limasunthira utsiwo mu gawo lotulutsa. Nthawi yomweyo, pali kuzungulira kodzaza chipinda ndi gawo latsopano la VTS.
2. Kukwera pamwamba chapakati chakufa, pisitoni imatseka polowera ndi kubwereketsa, zomwe zimatsimikizira kukakamizidwa kwa BTC pamalo omwe ali pamwambapa (popanda njirayi, kuyaka koyenera kwa chisakanizo ndi zomwe zimafunikira zamagetsi ndizosatheka). Nthawi yomweyo, gawo lina la chisakanizo cha mpweya ndi mafuta chimayamwa mumimbamo pansi pa pisitoni. Ku TDC ya pisitoni, timatulutsa timadzi tomwe timayatsa mafuta osakaniza ndi mpweya. Sitiroko yogwira imayamba.

Izi zimabwereza kuyendetsa njinga. Zimapezeka kuti pakamenyedwa kawiri, zikwapu zonse zimachitika ndikumenyedwa kawiri kwa pisitoni: pomwe imakwera ndi kutsika.

Chipangizo cha injini yamagetsi awiri?

Makina oyaka moto oyenda mkati ophatikizika amakhala ndi:

• Carter. Ili ndiye gawo lalikulu la kapangidwe kake ka crankshaft yokhala ndi mayendedwe a mpira. Kutengera kukula kwa gulu la silinda-pisitoni, padzakhala cranksha yofanana pa crankshaft.
• Pisitoni. Ichi ndi chidutswa chokhala ngati galasi, chomwe chimamangiriridwa ku ndodo yolumikizira, yofanana ndi yomwe imagwiritsidwa ntchito mu injini zamagetsi zinayi. Ili ndi poyambira pamakina ampikisano. Kuchita bwino kwa unit panthawi yoyaka moto ya MTC kumadalira kuchuluka kwa pisitoni, monga mitundu ina yamagalimoto.
• Kulowera ndi kubwereketsa. Amapangidwa mu nyumba yoyaka yamkati yamkati momwe mumakhala zolumikizira ndi zotulutsa zambiri. Palibe makina ogawira mpweya mu injini yotere, chifukwa choti sitiroko iwiri ndi yopepuka.
• Valavu. Gawo ili limalepheretsa mpweya / mafuta osakanikirana kuti abwererenso mgawo lolowera. Pisitoni ikakwera, phukusi limapangidwa pansi pake, kusunthira chipikacho, momwe gawo latsopano la BTC limalowera. Mukangopwetekedwa ndi sitiroko yogwira ntchito (mphamvu idayambitsidwa ndipo kusakaniza kunayaka, ndikusunthira pisitoniyo pansi pakufa), valavu iyi imatseka.
• Kuponderezana mphete. Awa ndi magawo ofanana ndi injini ina iliyonse yoyaka mkati. Makulidwe awo amasankhidwa mosamalitsa kutengera kukula kwa pisitoni inayake.

Hofbauer kapangidwe kake kawiri

Chifukwa cha zopinga zambiri za uinjiniya, lingaliro logwiritsa ntchito masinthidwe amitengo iwiri mgalimoto zonyamula lakhala likutheka mpaka posachedwa. Mu 2010, kupambana kwachitika pankhaniyi. EcoMotors idapeza ndalama zabwino kuchokera ku Bill Gates ndi Khosla Ventures. Chifukwa cha zinyalala zoterezi chinali kuwonetsedwa kwa injini yoyamba yankhonya.

Ngakhale kuti kusinthaku kwakhalapo kwanthawi yayitali, a Peter Hofbauer adapanga lingaliro loti amenyedwe kawiri omwe adagwira ntchito pamasewera a nkhonya wakale. Kampaniyo idatcha ntchito yake OROS (yotanthauziridwa ngati zonenepa zotsutsana ndi ma pistoni otsutsana). Chipangizochi sichitha kugwira ntchito pa mafuta okha, komanso pa dizilo, koma wopanga adakhazikika pamafuta olimba.

Tikaganizira mamangidwe tingachipeze powerenga za sitiroko awiri mu mphamvu imeneyi, ndiye chiphunzitso, angagwiritsidwe ntchito kusinthidwa ofanana ndipo anaika zonyamula 4-gudumu galimoto. Zikanakhala zotheka pakadapanda miyezo yazachilengedwe komanso kukwera mtengo kwa mafuta. Pogwiritsira ntchito injini yoyaka moto yapakatikati kawiri, gawo lina lamafuta amafuta limachotsedwa kudzera padoko lotulutsa utsi mukamayeretsa. Komanso, pakuwotcha kwa BTC, mafuta amawotchedwanso.

Ngakhale kukayikira kwakukulu kwa mainjiniya ochokera kwa opanga makina otsogola, injini ya Hofbauer idatsegula mwayi kuti zikwapu ziwiri zilowe pansi pagalimoto zamtengo wapatali. Tikayerekezera chitukuko chake ndi nkhonya wachikale, ndiye kuti chatsopano ndi chopepuka 30%, popeza kapangidwe kake kamakhala ndi magawo ochepa. Chiwonetserochi chikuwonetsanso kupanga mphamvu kwamphamvu pantchito poyerekeza ndi womenyera nkhonya anayi (kuwonjezeka moyenera mkati mwa 15-50%).

Mtundu woyamba wogwira ntchito udalandira cholemba EM100. Malinga ndi wopanga mapulogalamuwa, kulemera kwake kwa mota ndi 134 kg. Mphamvu yake ndi 325 hp ndipo makokedwe ndi 900 Nm.

Kapangidwe ka nkhonya watsopano ndikuti ma pistoni awiri ali mu silinda imodzi. Iwo wokwera pa crankshaft yemweyo. Kuyaka kwa VTS kumachitika pakati pawo, chifukwa chomwe mphamvu yomwe imatulutsidwa imakhudza ma pistoni onsewo. Izi zikufotokozera makokedwe akulu chotere.

Chosemphana ndi china chimakonzedwa kuti chizigwira ntchito moyandikana ndi pafupi. Izi zimatsimikizira kuzungulira kosalala kopanda kugwedezeka ndi makokedwe okhazikika.

Kanemayo, Peter Hofbauer mwiniwake akuwonetsa momwe mota yake imagwirira ntchito:

injini ya opoc momwe imagwirira ntchito.mp4

Tiyeni tiwone mawonekedwe ake amkati ndi kapangidwe kake ka ntchito.

Kutembenuza

Turbocharging imaperekedwa ndi malo othamangitsira pamtengo womwe amaikapo mota yamagetsi. Ngakhale zimayenda pang'ono kuchokera kumtunda wamafuta, zotsatsira zamagetsi zoyendetsa zimalola kuti zoyendetsazo zizithamanga kwambiri ndikupanga mpweya. Pofuna kubwezera mphamvu yogwiritsira ntchito magetsi poyendetsa galimotolo, chipangizocho chimapanga magetsi magetsi akamagwiritsa ntchito mpweya. Zamagetsi zimathandiziranso kutulutsa utsi kuti muchepetse kuwonongeka kwa chilengedwe.

Izi ndizomwe zimayambitsa kupwetekedwa kawiri ndizotsutsana. Kuti mupange mwachangu mpweya wofunikira, mota wamagetsi uwononga mphamvu zambiri. Kuti muchite izi, galimoto yamtsogolo, yomwe idzagwiritse ntchito ukadaulowu, iyenera kukhala ndi jenereta yabwino kwambiri komanso mabatire okhala ndi mphamvu zambiri.

Kuyambira lero, mphamvu yamagetsi yamagetsi ikadali papepala. Wopanga akuti dongosololi limathandizira kuyeretsa kwa silinda kwinaku likuwonjezera phindu la magawo awiri a sitiroko. Mwachidziwitso, kuyika uku kumakupatsani mwayi wopitilira mphamvu ya malitawo poyerekeza ndi ena omwe ali ndi sitiroko zinayi.

Kukhazikitsidwa kwa zida zotere kumapangitsa kuti magetsi akhale okwera mtengo kwambiri, ndichifukwa chake kuli kotsika mtengo kugwiritsa ntchito injini yoyaka yamphamvu yamkati komanso yosusuka kuposa nkhonya yatsopano yopepuka.

Zitsulo kulumikiza ndodo

Mwa kapangidwe kake, chipangizocho chikufanana ndi injini za TDF. Pokhapokha pakusinthaku, ma pistoni otsutsana sanakhazikitse zipolopolo ziwiri, koma imodzi chifukwa cha zingwe zazitali zolumikizira ma pistoni akunja.

Ma pistoni akunja mu injini amakhala pa ndodo zazitali zolumikizira zachitsulo zomwe zimalumikizidwa ndi crankshaft. Sapezeka m'mphepete, monga momwe amasinthira achikale, omwe amagwiritsidwa ntchito pazida zankhondo, koma pakati pa zonenepa.

Zinthu zamkati zimalumikizidwanso ndi makina oyeserera. Chida choterocho chimakupatsani mwayi wopeza mphamvu zochulukirapo pakuwotcha kwa mafuta osakanikirana ndi mpweya. Galimotoyo imakhala ngati ili ndi zibangili zomwe zimapangitsa kuti pisitoni iwonjezeke, koma shaftyo ndi yaying'ono komanso yopepuka.

Crankshaft

Galimoto ya Hofbauer ili ndi kapangidwe kake. Zipangizo zamagetsi zimatha kuzimitsa zina mwazipangizo, kuti galimoto izitha kugwiritsa ntchito ndalama zambiri ikakhala kuti ICE ili ndi katundu wochepa (mwachitsanzo, mukamayenda pa mseu wathyathyathya).

Mu injini za 4-stroke zomwe zili ndi jekeseni wachindunji (kuti mumve zambiri za mitundu ya jakisoni, werengani kubwereza kwina) Kutseka kwa zonenepa kumatsimikiziridwa ndikuletsa mafuta. Pachifukwa ichi, ma pistoni amayendabe pamiyala chifukwa cha kuzungulira kwa crankshaft. Samangotentha mafuta.

Ponena za kutukuka kwatsopano kwa Hofbauer, kutsekedwa kwa zonenepa kumatsimikiziridwa ndi cholumikizira chapadera chokhazikitsidwa pachipindacho pakati pa mapaipi ofanana a silinda-pisitoni. Gawolo likadulidwa, gululi limangodula gawo la crankshaft lomwe limayang'anira gawo lino.

Popeza kusuntha ma pistoni mu injini yoyaka moto yapakati pa 2-stroke pamayendedwe opanda pake kumayimiranso gawo latsopano la VTS, pakusintha uku gawoli limasiya kugwira ntchito palimodzi (ma pistoni amakhalabe otayika). Mwamsanga pamene katundu mphamvu wagawo ukuwonjezeka, pa nthawi ina zowalamulira ndi kulumikiza gawo zosagwira wa crankshaft ndi, ndi galimoto kumawonjezera mphamvu.

Silinda

Pogwiritsa ntchito mpweya wabwino wamphamvu, mavavu oyenda-pang'ono amatulutsa gawo limodzi losakanikirana m'mlengalenga. Chifukwa cha izi, magalimoto okhala ndi magetsi otere sangathe kukwaniritsa zachilengedwe.

Pofuna kuthetsa vutoli, wopanga makina opikisana ndi sitiroko awiri apanga kapangidwe kazitsulo zina. Amakhalanso ndi malo ogulitsira, koma komwe amakhala kumachepetsa mpweya woipa.

Momwe injini yoyaka yamkati yamkati imagwirira ntchito

Chochititsa chidwi cha kusinthidwa kwazithunzithunzi ziwiri ndikuti crankshaft ndi pisitoni zili mchimbudzi chodzaza ndi mafuta osakaniza ndi mpweya. Valavu yolowera imayikidwa polowera. Kukhalapo kwake kumakuthandizani kuti mupange zovuta m'mimbamo pansi pa pisitoni ikayamba kupita pansi. Mutuwu umathandizira kutsuka kwamphamvu ndi kutulutsa mpweya.

Pisitoni ikamayenda mkati mwamphamvu, imatsegula / kutseka polowera ndi potuluka. Pachifukwa ichi, kapangidwe kazinthu kameneka kamathandizira kuti asagwiritse ntchito njira yogawa gasi.

Kuti zinthu zopaka zisatope mopitirira muyeso, zimafunikira mafuta apamwamba. Popeza ma mota awa ali ndi mawonekedwe osavuta, amasowa makina othira mafuta omwe amaperekera mafuta mbali zonse za injini yoyaka mkati. Pachifukwa ichi, mafuta ena amafuta amawonjezera mafuta. Pachifukwa ichi, mtundu wapadera umagwiritsidwa ntchito pazigawo ziwiri. Izi zimayenera kusungunula mafuta kutentha kwambiri, ndipo zikawotchedwa limodzi ndi mafuta, siziyenera kusiya mpweya.

Ngakhale ma injini ophulika awiri sanapezepo kugwiritsidwa ntchito kwakukulu kwamagalimoto, mbiri imadziwa nthawi yomwe injini zotere zimapezeka pansi pa magalimoto ena (!). Chitsanzo cha ichi ndi gawo lamagetsi la YaAZ.

Mu 1947, pamzere wa 7-silinda dizilo injini ya kapangidwe kameneka adaikidwa pamagalimoto matani 200 YaAZ-205 ndi YaAZ-4. Ngakhale inali yolemera kwambiri (pafupifupi makilogalamu 800), chipangizocho chinali chaching'ono kuposa makina amkati oyaka amgalimoto onyamula. Cholinga chake ndikuti chipangizochi chimaphatikizapo ma shaft awiri omwe amasinthasintha mogwirizana. Makina osanjikizawa amachepetsa kugwedezeka kwamphamvu mu injini, komwe kumatha kusokoneza thupi lamagalimoto amtengo.

Zambiri pazokhudza magwiridwe antchito a 2-stroke motors zafotokozedwa muvidiyo yotsatirayi:

2 CHIWERENGERE. Tiyeni tiyesetse kumvetsetsa ...

Kodi galimoto yama stroke-stroke ikufunika pati?

Chipangizo cha injini ya 2-stroke ndi chosavuta kuposa analogue ya 4-stroke, chifukwa chomwe chimagwiritsidwa ntchito m'mafakitale omwe kulemera ndi voliyumu ndizofunikira kwambiri kuposa mafuta ndi magawo ena.

Mwachitsanzo, magalimoto amtunduwu amaikidwa pamakina otchetchera kapinga wopepuka komanso zida zodulira minda yamaluwa. Kusunga mota wolemera m'manja mwanu zimapangitsa kuti zikhale zovuta kugwira ntchito m'munda. Lingaliro lomwelo lingathetsedwe pakupanga ma sewa.

Kugwiritsa ntchito kwake bwino kumadaliranso kulemera kwa madzi ndi mayendedwe amlengalenga, motero opanga amanyengerera pakugwiritsa ntchito mafuta ambiri kuti apange nyumba zopepuka.

Komabe, ma tatnik awiri amagwiritsidwa ntchito osati munjira zaulimi komanso mitundu ina ya ndege. M'masewera a auto / moto, kulemera ndikofunikira monga ma glider kapena makina otchetchera kapinga. Kuti galimoto kapena njinga yamoto izithamanga kwambiri, opanga, opanga magalimoto otere, amagwiritsa ntchito zinthu zopepuka. Zambiri pazinthu zomwe matupi amamagalimoto amafotokozedwera apa... Pachifukwa ichi, ma injiniwa ali ndi mwayi kuposa anzawo olemera komanso ovuta kwambiri a 4-stroke.

Nachi chitsanzo chaching'ono chantchito yakusintha kwamitenda iwiri yamphamvu yoyaka mkati yamasewera. Kuyambira 1992, njinga zamoto zina zakhala zikugwiritsa ntchito injini yaku Japan ya Honda NSR4 500-cylinder V-twin mu njinga zamoto za MottoGP. Ndi buku la malita 0.5 wagawo anayamba 200 ndiyamphamvu, ndi crankshaft ndi kupota mpaka 14 zikwi kusintha pamphindi.

Makokedwewo ndi 106 Nm. zafika kale pa 11.5 zikwi. Kuthamanga kwakukulu komwe mwana wotereyu adatha kupitilira kunali makilomita opitilira 320 pa ola (kutengera kulemera kwa wokwera). Kulemera kwa injini yokha kunali makilogalamu 45 okha. Kilogalamu imodzi yolemera yamagalimoto imakhala pafupifupi theka limodzi ndi theka. Magalimoto ambiri amasewera amasilira kuchuluka kwa mphamvu iyi.

Kuyerekeza kwa sitiroko iwiri ndi injini zinayi

Funso ndilakuti, ndiye, makina sangakhale ndi gawo lopindulitsa? Choyamba, sitiroko yapawiri ndiyo gawo lowononga kwambiri pazonse zomwe zimagwiritsidwa ntchito mgalimoto. Chifukwa cha izi ndizodziwika bwino za kuyeretsa ndi kudzazidwa kwa silinda. Kachiwiri, pakusintha kwa liwiro ngati Honda NSR500, chifukwa cha kuthamanga kwapamwamba, moyo wogwira ntchito wagawo ndilochepa kwambiri.

Ubwino wa 2-stroke unit pa 4-stroke analogue ndi monga:

• Kukhoza kochotsa mphamvu pakasinthidwe kamodzi ka crankshaft ndikokwera 1.7-XNUMX kuposa komwe kumapangidwa ndi injini yachikale yomwe imagwiritsa ntchito magetsi. Chizindikiro ichi ndi chofunikira kwambiri paukadaulo wapamadzi wotsika kwambiri komanso mitundu yama ndege yama piston.
• Chifukwa cha kapangidwe kake ka injini yoyaka yamkati, ili ndi miyeso yaying'ono komanso kulemera. Chizindikiro ichi ndi chofunikira kwambiri pamagalimoto opepuka ngati ma scooter. Poyamba, zida zamagetsi zotere (nthawi zambiri kuchuluka kwawo sizinapitirire malita 1.7) zidayikidwa mgalimoto zazing'ono. Mukusintha koteroko, kuwombera m'chipinda chopepuka kunaperekedwa. Mitundu ina yamagalimoto inalinso ndi injini zamaoko awiri. Kawirikawiri mphamvu ya injini zoyaka zamkati zamkati zinali pafupifupi malita 4.0. Kuphulika kwa kusintha koteroko kunachitika ndi mtundu wowongoka.
• Ziwalo zawo zimachepa pang'ono, popeza zinthu zomwe zimasunthira, kuti zikwaniritse zofanana ndi ma 4-stroke analogs, zimayenda kangapo konse (zikwapu ziwiri zimaphatikizidwa ndi sitiroko imodzi).

4-sitiroko galimoto

Ngakhale panali maubwino awiriwa, kusinthidwa kwa ma sitiroko awiri kumakhala ndi zovuta zina, chifukwa sichinagwiritsidwe ntchito mgalimoto. Nazi zina mwa izi:

• Mitundu ya Carburetor imagwira ntchito ndikutaya ndalama zatsopano za VTS panthawi yoyeretsa chipinda champhamvu.
• Mu mtundu wa 4-stroke, mpweya wotulutsa mpweya umachotsedwa kwambiri kuposa momwe analili analogue. Chifukwa chake ndikuti pakamenyedwe ka 2, pisitoniyo sichifika pamwamba pomwe imapukutidwa, ndipo njirayi imangowonongedwa pakangolowa. Chifukwa cha ichi, mafuta ena osakanikirana ndi mpweya amalowa mu utsi, ndipo mpweya wambiri umatsalira mu silinda momwemo. Kuti muchepetse kuchuluka kwa mafuta osayaka mu utsi, opanga amakono apanga zosintha ndi jekeseni, koma ngakhale pakadali pano sizingatheke kuchotsa zotsalira zoyaka moto mu silinda.
