Silinda imodzi: kutamanda chifukwa chosavuta

Poyambirira, njinga yamoto inali silinda imodzi, yosavuta komanso yaying'ono. Yokwera pamakina owonda komanso opepuka, idapanga nthano ndi BSA Gold Stars, Norton Manx ... ndi Yamaha 500 XT ...

Mpikisano wa zida

Mutu wa silinda wa KTM 450 uwu pawokha umawonetsa kuphatikizika kwa silinda imodzi ndikufotokozera kupepuka kwake.

Kusintha kwachilengedwe kwa njinga zamoto zamakono kukupita ku chitonthozo chowonjezereka, kuthamanga kwambiri, kudalirika kwambiri. Madera omwe sali ovomerezeka a mono. Zowonadi, zosakhala bwino m'chilengedwe komanso kupereka kusinthasintha kwapang'onopang'ono, zimagunda movutikira, zomwe zidapangitsa kuti atchulidwe "Tuper" (wodziwa bwino chilankhulo cha Shakespeare). Kuonjezera apo, pofufuza ntchito, silinda imodzi imachepetsedwa. Ndizomveka, chifukwa kuti muwonjezere mphamvu, mutha kuwonjezera kusuntha kapena kuthamanga kwa injini. M’zochitika zonse ziŵirizo, iye amavomereza zolephera zake. Ngati kusuntha kukuwonjezeka, pisitoni imakula, motero imakhala yolemera. Ndipotu, mphamvu za inertia zomwe zimayambitsa kuvala ndi kugwedezeka zimawonjezeka nthawi yomweyo. Vuto lomwelo ngati tikuyesera kuti tifike pa liwiro lalitali, chifukwa mphamvu zopanda mphamvu zimakula pamtunda wa liwiro, timakumana ndi zoopsa zomwezo zakusweka, kuvala ndi kugwedezeka…. Chifukwa chake, mono iyenera kukhala ndi mphamvu zapakatikati, osadzinamiza kuswa mbiri .... M'malo mwake, kupambana kwake komaliza kwa Utsogoleri Waukulu kunali mu 1969. Anali a Norton Mans, ndipo mpikisano unali mumvula. Kenako ma silinda angapo, 2 ndi 4 zikwapu, pomaliza zidalowa m'malo mwake.

Nkhondo itatha, masilindala apamwamba achingerezi anali chida chachikulu chosankha oyendetsa ndege omwe akufuna kuthawa. Komabe, adayenera kusintha mafelemu kumapeto kwa zaka za m'ma 1960 poyang'anizana ndi kupita patsogolo kwa ma stroke awiri ndi ma silinda ambiri. Nayi Matchless G 50: Anali mpikisano ku Norton Manx. Inali ndi injini yosavuta ya ACT.

Yamaha akuganiziranso za gromono

Ndine nthano. ACT mpweya umodzi udaziziritsa injini ya 2 valve, kuyambitsa kugwedezeka ndi mabuleki a ng'oma. 500 XT ndiyosiyana ndi kupita patsogolo, koma idzakhala yopambana. Ndiko kwa iye kuti tiyenera kubwezera mabingu.

Komabe, mu 1976 Yamaha adasintha ukadaulo uwu, ndikupeza kuti ndi malo osinthika bwino: Cross Country Running. Kuphatikiza, ndalama, zodzaza ndi mawonekedwe, silinda imodzi ndiyo kupambana padziko lonse lapansi kwa 500 XT. Mpikisano anatsatira mwamsanga kwambiri, ndi chodabwitsa anatenga mochuluka mosayembekezereka ndi chitukuko cha Paris Dakar. Njira ya silinda imodzi imakhala chizindikiro cha ufulu, ulendo ndi kuthawa. Tili kumayambiriro kwa zaka za m'ma 1980. Koma mbiri imapunthwa pamene BMW imathamanga ndi mapasa ake otchuka. Ngakhale kuyesayesa kwake, kuwonjezereka kwa kusamuka, kuchulukitsa ma valve, kawiri ACT, ndi zina zotero, mono sangathe kupirira mafunde amitundu yambiri. Kupanga phula, akuweramira kunjira zamchenga. Wamwaliradi? Ayi ndithu, silinda imodzi ndi njira ya rustic yomwe imatha kupirira nkhanza. Chifukwa chake, adzabadwanso kuchokera phulusa lake, ngati Phoenix.

Bastion yotsiriza, nkhondo zotsiriza

Bwererani ku Chisomo: Kugwiritsa ntchito ukadaulo wothamanga kunalola ma monos kubwereranso mphamvu ndikupambana nthawi zonse mokomera kufanana. TT ikadali malo okhawo omwe ma silinda amodzi a Hi-Tech akadalipo. Nayi mozondoka Yamaha 450 amapasa ACT Yamaha XNUMX mutu wa silinda ndi jakisoni.

Tsopano njira yokhayo ndiyo SUV yoyera komanso yolimba. Apa, kulemera ndi kuphatikizika ndi mikhalidwe yofunika yomwe imaposa mphamvu zoyera. N’zosatheka kuyenda mahatchi 200 kapena kuposerapo m’dera lamatope lodzaza ndi mabwinja. Ndikosathekanso kuthana ndi makina olemera pafupifupi 4 kg. Palibe malo a multi-cylinder (panobe). Koma mpaka posachedwa, 2-stroke mono sakanatha kulimbana ndi 125-stroke ndi kusamutsidwa kofanana. Koma pamene kuwongolera kuipitsidwa kolimba kumakankhira kukankhira-koka kuchoka (motsindika, mbiri imadzibwerezanso kachiwiri!), Imadzikakamiza yokha. M'malo mwa kufanana kusamuka kwa 2 250 bits / 4 250 zikwapu ndi 2 450 bits 4 4 zikwapu, tikuwona kubadwa kwa mtundu watsopano wa masilinda apakati osamutsidwa omwe ali amphamvu, opepuka komanso ogwira mtima. Mbadwo watsopanowu wa masilindala amodzi apamwamba kwambiri sungathe kuwerengedwa. Double ACT, ma valve 100 a titaniyamu, madzi oziziritsidwa, ma pistoni opangira ... Ndiwopitilira 13000 hp. ndi kusunga liwiro la 250 rpm pa XNUMX !!!

Mitundu yosinthika iyi ikuyang'ananso phula chifukwa cha mafashoni apamwamba kwambiri, ndi chikhumbo chofuna kutengeranso malowa. Mono molimba!

Wopanga ku Austria KTM akadali woteteza wa silinda imodzi yotentha kwambiri pamsewu. Kuchita ndi kudalirika kwa 690 yake ndikosangalatsa kwa mono. Nayi injini ya 500 EXC.

Bokosi: 2 bits

Silinda imodzi yamphamvu yolimba, yopepuka, yosavuta, yokhala ndi sitiroko 2 inali ndi nthawi yake yabwino kwambiri.

Kusintha kwaposachedwa kwa miyezo yowononga kuwonongeka kwamulepheretsa pang'ono, koma analibenso mawu ake omaliza ... oyendetsa ndege a TT omwe anasankha injini za valve sizinaphatikizepo kapena kukumba ndalama zowonjezera zowonjezera zomwe zingayambitse izi. Injini zovuta kwambiri zomwe zimathamanga mwachangu, zomwe zimafunikira kukonzanso pafupipafupi (ma cheke chilolezo cha ma valve, unyolo wogawa, kuvala kwambiri kwa ma valve a titaniyamu okhala ndi fumbi ...). Zonsezi ndi zodula ... Ena akuyamba kuganiza kuti potsiriza, masilindala okhala ndi mabowo ... Sizinali zoipa kwambiri!
