Amasilinda amathathu

Kuthiwani uma bekuyiNJINI yesithuthuthu esezingeni eliphezulu?

Esikhathini esedlule besazi i-3-cylinder 2-stroke, ku-inthanethi ku-Kawasaki, Suzuki ne-Motobécane noma okumise okwe-V ku-Honda. Eqinisweni, kwaHonda, lawa kwakungamamotho aqondile, amasilinda awo anyakaziswa ukuze athole ububanzi. Kwakukhona induku eyodwa kuphela yokuxhuma i-manequin ngayinye, futhi isilinda ngasinye sasinoqwembe lwaso lwepompo oluzimele. Lezi zinjini bezifakwe ama-PSA angu-400 emigwaqo kanye nama-500 RS kanye nama-NS GPs. Imininingwane ehlekisayo, izakhiwo ezisetshenzisiwe zihlanekezelwe: amasilinda avundlile angu-2 kanye nelinye eliqondile emgwaqweni, okuphambene ku-GP. Mhlawumbe ezindabeni eziphathelene nokudlula kwezimbiza zokuphumula kanye nokushisa okukhishiwe ...

Kafushane, izinjini ezinamasilinda amathathu kulezi zinsuku ziyizinjini ezinomoya oseyili wazo, kodwa zonke zinesakhiwo esifanayo: injini esemgqeni kanye nomjikelezo wama-4-stroke, ngoba i-two-stroke ayisekho umoya ngaphakathi. amaseyili akhe...

Okukodwa kubo bonke, konke ku-inthanethi!

Ukuze uthole ukulinganisa okuphelele mayelana nokudlidliza kanye nokujwayelekile kwe-cyclical, i-crankcase ibekwe njalo ngo-120 ° ukuze isebenze njalo, ivutha njalo ngo-240 ° (ithuba elilodwa / 2). Ngo 70s / 80s Laverda wakhulula 180 ° ezintathu-cylinder 1000, injini okuyinto "uphawu" kakhulu kuka izinguqulo ezalandela 120 °. Le moto, eqanjwe ngokuthi "Jota" ngemuva kweyodwa yesi-Spanish ene-stroke emithathu, isehlukile.

4-stroke amasilinda amathathu ku-GP

Injini enamasilinda amathathu iphinde yasebenza kahle kakhulu ku-GP, okokuqala ezitebhisini ezi-4, esikhathini esikhazimulayo se-MV Agusta, kwase kulandela izinyathelo ezi-2. Isikhathi esidlule sayo siyakhazimula kangangokuthi nanamuhla i-800 F3 ingeye-MV3 350 edumile (1965) kanye ne-500 (1966). 500 athuthukiswe mayelana 80 hp. ku-12 rpm futhi idlule ku-000 km / h. Uwine okungenani izicoco zomhlaba eziyisi-270 phakathi kuka-6 no-1966 ezandleni zika-Giacomo Agostini! Uma imishini ebonakalayo ithatha lesi sakhiwo se-fetish, izinjini zesimanje zifaka i-crankshaft ezungezayo enciphisa umphumela we-gyroscopic wesithuthuthu futhi ithuthukise ukushesha kwaso.

Sisanda kubona i-GP yamasilinda amathathu futhi ngesikhathi sithuthukela ku-four-stroke. Ngo-2003, nokho, iguqulwe njenge-Aprilia Cube, yayingagculisi kakhulu kune-VM. Eqinisweni, lo mshini uhlanganisa ubuncane obuhlobene kanye nekhono lokushintshana futhi ngaleyo ndlela kuthuthukiswe amandla athile amakhulu uma kuqhathaniswa. “Ngokulinganiselwe” cishe kuyingxenye yenkinga yase-Cuba, ngoba manje kufanele ufinyelele isivinini esikhulu ukuze uziphoqelele kudokotela wakho.

Amamodi angahambisani nezakhiwo ezingahlukanisi ngokwanele ekuthuthweni. Lokhu kujezisa isivinini somugqa wepiston, njengoba sizoxoxa kamuva. Ngezimbambo ezingu-88,6 X 53,5 "ezimenyezelwe", i-cube izabalaza ukudlula i-15 rpm. Ukudla kuphansi kakhulu, kunobubanzi obuncane. Umphumela waba injini enonya eyakhinyabeza ukubamba nokubamba kalula ukushayela.

Ukulingana

Kungenxa yalesi sizathu ukuthi esigabeni se-supersport, njengaku-SBK, amasilinda amathathu athole inzuzo ye-offset ngaphezu kwamasilinda angu-4. Ngakho-ke sibone ukushaywa kwe-675 cc yamasilinda amathathu e-MV kanye ne-Triumph ngokumelene ne-3 cc 600 cylinder. Ku-SBK ngesikhathi sama-3 4-cylinder, 750-cylinder amathathu kanye ne-4 twin-cylinder. Lokhu kwavumela iPetronas ukuthi isebenzise i-900 ethakazelisayo enenjini ehlanekezelwe: igesi engemuva, indawo yokungena ngaphambili namasilinda atshekele emuva). Isibonelo esihle "semilenze emithathu".

Umthetho wokukhuthazela ungamasilinda amane angama-600, kodwa kumasilinda amathathu kuyadingeka ukudlula u-750 cm3. Umehluko awutholakali ku-GP, ikakhulukazi namuhla, lapho imithetho ibeka ubuningi bamasilinda angu-4 kanye nebhore elingekho ngaphezu kuka-81mm. Eqinisweni, ubukhulu be-GP engama-cylinder amathathu, obulungiswa kahle kakhulu, buzoba ngu-81 X 48,5 mm noma isivinini esiphezulu esingaba ngu-17 rpm ngesivinini se-piston esingu-000 m / s. Ngokungeziwe kubukhulu bamandla ehhashi, mhlawumbe okulungile kancane, kukhona ukuguga okusheshayo okufanele ukuxwaye, okungahambisani nenani lezinjini ezivunyelwe isizini ngayinye. Ngakho-ke, ngaphandle kokubheka ubunzima, akekho ozobe eqasha i-three-cylinder kuze kube kuphinde kwaqashelwa.

Encane kodwa eqinile

Uma kuziwa emijahweni yemigwaqo nezemidlalo, i-triple iyaziba lezi zinkinga. Udlala ngokubumbana kwakhe (800 MW unesisindo esingu-52 kg kuphela!) Ukusevisa izithuthuthu ezihlale zijabulisa kakhulu ngenxa yokushuna kwakhe, okumnika impendulo emnandi kakhulu kanye nokuba khona kwangempela. Lokhu kufakazelwa amajika aphuma ebhukwini lenjini elaziwayo. Okokuqala, sibona itorque esheshayo yenjini engu-1616cc (3 X 3cc) enamasilinda amathathu.

Kukhona ukuphakama okungu-603 Nm, kanti kwelandelayo amasilinda angu-4 2155 (4 X 538 cm3), athuthukisa i-torque ephakathi nendawo (180 Nm vs 135), ane-torque engu-425 Nm kuphela esheshayo.

Ngamafuphi, ngokugudluka okuncane kanye ne-torque emaphakathi ephansi, iziqongo ze-torque zamasilinda amathathu ziphakeme kakhulu kunenjini engu-4-cylinder, okusho ukuthi umshayeli uzojabula kakhulu.

isiphetho

Kungakhathaliseki ukuthi i-trail mount, i-roadster noma i-sports car mount, iyinjini ekhangayo encane futhi elula kune-four-cylinder. Izimfanelo ezimthembisa ikusasa eliqhakazile ngamasondo amabili noma amane. Ngempela, kancane kancane iphinde ibekwe ngaphansi kwama-hood ezimoto zanamuhla ezinguqulweni ezine-supercharging ye-1000 noma i-1200 cm3. Nakanjani, akakaqedi ukusimangaza!
