Isilinda esisodwa: indumiso ngobulula

Ekuqaleni, isithuthuthu sasiyi-cylinder eyodwa, ilula futhi ihlangene. Ifakwe emishinini emincane nelula, yakha inganekwane nge-BSA Gold Stars, Norton Manx ... kanye ne-Yamaha 500 XT ... Kodwa ngokuhamba kweminyaka abashayeli bamabhayisikili bacela okwengeziwe ngezikhwezi zabo futhi i-mono yathatha idiphu.

Umjaho wezingalo

Leli khanda lesilinda le-KTM 450 ngokwalo libonisa ukubumbana kwesilinda esisodwa futhi lichaza ukukhanya kwalo.

Ukuziphendukela kwemvelo kwezithuthuthu zanamuhla kuqhubekela phambili ekunethezekeni okwengeziwe, isivinini esikhulu, ukwethembeka okwengeziwe. Izindawo okungezona igunya le-mono. Impela, ingalinganiseli emvelweni futhi ihlinzeka ngokujwayelekile kwama-cyclical, ishaya kakhulu kuma-revs aphansi, okuyenze yabizwa ngesidlaliso "Tuper" (isazi ngolimi lukaShakespeare). Ngaphezu kwalokho, ekusesheni ukusebenza, isilinda esisodwa sinciphisa. Kunengqondo, ngoba ukwandisa amandla, ungakwazi noma ukwandisa displacement noma isivinini injini. Kuzo zombili izimo, uyakuvuma ukulinganiselwa kwakhe. Uma ukufuduka kukhuphuka, i-piston iba nkulu, ngakho-ke ibe nzima. Eqinisweni, amandla e-inertia abangela ukuguga nokudlidliza ayanda ngesikhathi esifanayo. Inkinga efanayo uma sizama ukufinyelela isivinini esikhulu, ngoba njengoba amandla angasebenzi akhula esigcawini sejubane, sibhekana nezingozi ezifanayo zokuphuka, ukuguga nokudlidliza…. Ngakho-ke, i-mono kufanele ikhawulelwe kumandla aphakathi nendawo, ngaphandle kokukwazi ukuzenza sengathi uphula amarekhodi…. Eqinisweni, ukunqoba kwakhe kokugcina kobuMongameli Obukhulu kwaba ngo-1969. BekuyiNorton Mans, umjaho ubuyidliva. Khona-ke amasilinda amaningi, imivimbo engu-2 no-4, ekugcineni ayishintsha.

Ngemva kwempi, amasilinda aphezulu angamaNgisi ayeyisikhali esiphezulu esikhethwa abashayeli bezindiza abazimele ababefuna ukubaleka. Kodwa-ke, kwakudingeka bashintshe amafreyimu ngasekupheleni kwawo-1960 lapho bebhekene nenqubekelaphambili ku-two-stroke kanye nama-multi-cylinder. Nansi i-Matchless G 50: Bekuyiqhudelana neNorton Manx. Ifaka injini ye-ACT elula.

U-Yamaha ucabanga kabusha ngokuzwakalayo

Ngiyinganekwane. ACT one air cooled 2 valve engine, shock start namabhuleki ezigubhu. I-500 XT iphambene nenqubekela phambili, kodwa izoba yi-hit. Kuyo kumele sibuyisele odumayo.

Kodwa-ke, ngo-1976 i-Yamaha yavuselela lobu buchwepheshe, yayithola iyindawo ejwayele ukulungiswa: I-Cross Country Running. Kuhlanganiswe, ukonga, kugcwele uhlamvu, isilinda esisodwa impumelelo yomhlaba wonke ye-500 XT. Ukuncintisana kwalandela ngokushesha okukhulu, futhi lesi simo sathatha izilinganiso ezingalindelekile ngokuthuthukiswa kwe-Paris Dakar. Umzila onesilinda esisodwa ube usuba wuphawu lwenkululeko, uhambo nokuphunyuka. Sisekuqaleni kweminyaka yawo-1980. Kodwa umlando uyakhubeka uma iBMW igijima newele layo eliyisicaba elidumile. Naphezu kwemizamo yayo, ukwandisa ukufuduka, ama-valve aphindaphindayo, i-ACT kabili, njll., i-mono ngeke ikwazi ukumelana ne-multi-cylinder wave. Elungiselela itiyela, akhothamela ezindleleni ezinesihlabathi. Ufile ngempela? Akunjalo, isilinda esisodwa siwumshini okwazi ukumelana nokuhlukunyezwa. Ngakho-ke, uzozalwa kabusha emlotheni wakhe, njengePhoenix.

Inqaba yokugcina, izimpi zokugcina

Buyela kuGrace: Ukusetshenziswa kobuchwepheshe bomjaho kuvumele ama-monos ukuthi abuyele emandleni futhi awine zombili izikhathi ngokuvuna ukulingana kokuchema. I-TT isalokhu kuwukuphela kwendawo lapho amasilinda awodwa e-Hi-Tech esatholakala khona. Nali i-Yamaha 450 iwele elibheke phansi le-ACT Yamaha XNUMX cylinder head kanye nomjovo.

Manje okuwukuphela kwendlela ehlukile iSUV ehlanzekile neqinile. Lapha, isisindo nokubumbana kuyizimfanelo ezibalulekile ezidlula amandla amsulwa. Akunakwenzeka ukuhamba amahhashi ayikhulu noma ngaphezulu endaweni enodaka egcwele amaqhubu. Akunakwenzeka futhi ukubhekana ngokuphumelelayo nomshini onesisindo esingaba ngu-200 kg. Asikho isikhala samasilinda amaningi (okwamanje). Kodwa kuze kube muva nje, i-mono ye-4-stroke ayikwazanga ukulwa ne-stroke engu-2 ngokususwa okulinganayo. Kodwa lapho kuqinisa izindinganiso zokulawula ukungcoliswa komoya kucindezela ukusunduza-kudonsela ekuphumeni (ngokugcizelela, umlando uyaziphinda futhi!), Kuyaziphoqa. Sivuna ukulingana kokugudluka kwamabhithi angu-125 2 / 250 4 imivimbo kanye namabhithi angu-250 2 450 4 imivimbo, sibona ukuzalwa kohlobo olusha lwamasilinda angawodwa aphakathi nendawo anamandla, angasindi futhi asebenza kahle. Lesi sizukulwane esisha samasilinda owodwa wobuchwepheshe obuphezulu asinakubalwa. I-Double ACT, ama-valve e-titanium angu-4, uketshezi olupholile, amapiston omgunyathi ... Angaphezu kuka-100 hp. futhi ugcine isivinini esingaba ngu-13000 rpm ku-250 !!!

Lolu hlobo oluguquguqukayo lubheka itiyela futhi ngenxa yemfashini yesimanjemanje, ngesifiso sokubuyisela lo mhlaba. Mono kanzima!

Umkhiqizi wase-Austrian i-KTM usengumvikeli onesilinda esisodwa esishisayo emgwaqeni. Ukusebenza nokuthembeka kwe-690 yayo kuyamangaza ku-mono. Nansi injini engu-500 EXC.

Ibhokisi: 2 amabhithi

I-compact enamandla, engasindi, elula, isilinda esisodwa esinama-stroke angu-2 sibe namahora aso akhazimulayo angaphandle komgwaqo.

Ukuziphendukela kwemvelo kwakamuva kwezindinganiso zokulawula ukungcola kuye kwamenza wangafaneleki kancane, kodwa futhi akazange abe nezwi lakhe lokugcina ... abashayeli bezindiza be-TT abakhetha izinjini ze-valve abazange bahlanganise noma bagaye izindleko ezengeziwe zokusebenza ezingaholela kulokhu. Izinjini eziyinkimbinkimbi ezisebenza ngokushesha, ezidinga ukunakekelwa okuvamile (ukuhlolwa kwe-valve clearance, uchungechunge lokusabalalisa, ukuguga okuphezulu kwamavalvu e-titanium anothuli ...). Konke lokhu kuyabiza ... Abanye sebeqala ukucabanga ukuthi ekugcineni, amasilinda anezimbobo ... Kwakungekubi kangako!
