Ukutholwa

I-Cocorico, okusungulwe okusha kwe-French, ingase ithuthukise ukusebenza kahle kwezinjini zethu maduzane kuyilapho yehlisa ukungcola nokusetshenziswa. Ubuchwepheshe bempumelelo yangempela lapho umncintiswano wezinga eliphezulu (GP noma i-Endurance) uzoba inkundla yokudlala enhle kakhulu. Ngenkathi silinde ukufika kuleli qophelo, i-lerepairedesmotards.com yethula i-Adaptha ye-APAV!

U-Romain Besret, unjiniyela ozifundisayo, unomsuka wawo kulokhu kusungulwa okunelungelo lobunikazi, okuyisihloko sezinkanuko eziningi. Kumelwe kushiwo ukuthi iguqula ukuphathwa kwezinjini "ze-compression ignition" (uphethiloli), okungafani nezinjini "zokushisa kokucindezela" (i-diesel ...), kufanele zisebenze ngokucebile njalo futhi empeleni zisebenzise i-valve yokuphefumula. Ngempela, njengesikhumbuzo, enjinini kaphethiloli, amandla alawulwa ngokuminyanisa okuthathwayo ukuze kuncishiswe ukugeleza komoya owuthathayo. Ngaphezu kwalokho, inani likaphethiloli elijovwe lilungiswa ngasikhathi sinye ukuze libe nesilinganiso esilungile somoya / uphethiloli. Ngamafutha edizili, ukudla kuhlale kuvuliwe ngokugcwele (akukho bhokisi levemvane), futhi amandla alawulwa ngokujova uphethiloli omningi noma omncane.

Ubuciko obuphezulu

Namuhla, izinhlelo ezine ezamukelekile zokuphatha umthwalo ziyasebenza. Eyakudala kakhulu ivalve uvemvane, etholakala ku-99,9% wezithuthuthu. Nokho, inezinkinga ezintathu. Okokuqala, kubekwa isithiyo epayipini lokulawula ukugeleza komoya ezindaweni eziphansi zesibambo, okudala ukulahlekelwa okukhulu kwengcindezi kanye nesiphithiphithi se-aerodynamic. Lesi sivimbelo siphinde simelane nempendulo ye-waveform namanye ama-acoustic chords avela enjinini uma ipayipi livinjwe kancane. Igagasi alisafinyeleli ekupheleni kwesiteshi njengoba lishaya uvemvane. Ngakho-ke, amasistimu okuthatha ubude obuguquguqukayo ayahluleka noma mancane futhi okungenani asebenzi kahle ekuvulekeni kwezibambo ezincane. Okwesibili, umjovo kaphethiloli uvamise ukungami kahle njengoba uchelela ipayipi kunokuba ufinyelele ngqo kuvalvu. Lokhu "ukumanzisa" kombhobho kuyingozi ezikhathini zokuphendula umjovo, ukusetshenziswa nokungcola, ikakhulukazi amakhaza. Ngempela, omunye uphethiloli osala odongeni lokudonsa amanzi awumuncwa injini uma uwudinga. Ngakolunye uhlangothi, lapho umshayeli enqamula i-throttle ngoba akasadingi amandla noma uphethiloli, ngakho-ke ukucindezeleka okunamandla kakhulu "kwe-siphons" kuyamqhubezela futhi kudonsa amaconsi asele kaphethiloli ekulahlekelweni kwenetha. Ukusebenzisa imibhobho yeshawa ebekwe ebhokisini lomoya kuvimbela izindonga ukuthi zingabi manzi, nokho, ukusebenzisa inkungu kaphethiloli ngokuqinisekile kuhle ekusebenzeni, kodwa hhayi ukudliwa. Ngaphezu kwalokho, njengoba i-injector itholakala ngemuva kovemvane, kude kakhulu ne-valve, impendulo yoshintsho oluyingxenye yomthwalo wokungenzi lutho ayilungile, futhi empeleni, i-injector yokugeza icishe isekelwe ngokuhlelekile i-injector evamile etholakala "ngaphesheya" ngokulandelayo. ku-valve. Njengebhonasi, kubiza ama-injection amabili isilinda kanye nokulawula okuza ne... tertio, uma i-throttle isinkulu, i-throttle ihlala ihlala phakathi nokugeleza, okusaphazamisa ukugeleza komthwalo ogcwele, okubangela ukulahlekelwa okuncane kakhulu kobukhulu. amandla. Akuyona i-glop.

I-Guillotine!

Cha, lokhu akusikho okufanelwe yi-butterfly, kuyinqubo eqhathaniswa nezihlahla eziyisicaba zama-carburetors ethu asendulo. Ixazulula inkinga eyodwa kuphela, inkinga yomthwalo ogcwele, njengoba ihlanza ngokuphelele umgudu. Kungcono ukuthola amandla aphezulu, kodwa ake silinganisele le nzuzo, sikhumbula ukuthi ngisho nasemathangeni, ekugcineni sisesimweni esifushane, ikakhulukazi uma ibhayisikili linamandla kakhulu! Esithuthuthuni se-GP, asikho ngaphezu kwama-35% esikhathi esivulekile ngokugcwele kumzila osheshayo. Ukuze uthole inkomba, ngeminyaka yawo-1990, i-500 GP yayicishe ibe yi-10% yesikhathi kusekethe yaseJerez!

Ibhasi elijikelezayo.

Ngokujwayelekile le divayisi isetshenziswa yi-KTM ezithuthuthu3. Inikeza izinzuzo ezifanayo njenge-guillotine yephrofayili yepayipi, impofu kancane emithwalweni eyingxenye. Kodwa kwabanye ... Lesi isigqoko esimhlophe nesimhlophe esinezixazululo ezimbili zangaphambilini.

Ukusabalalisa okuguquguqukayo

Inqubo yokugcina, engatholakali ezithuthuthu namuhla, iwukukhipha i-throttle valve noma enye isistimu efanayo nokulawula ukugeleza komoya noma ukunikezwa okuguquguqukayo okungu-100%, okushintsha ukuphakanyiswa kwama-valve nezikhathi zokuvula ama-valve ukuze kufane nezidingo zamandla ezivezwa umshayeli. Uma ungenzi lutho, ama-valve avuleka ngokuphakama okuphansi kakhulu futhi phakathi nesikhathi esifushane kakhulu. Uma zilayishwe ngokugcwele, zithatha isikhathi eside ukusukuma futhi ngenxa yalokho zithatha isikhathi eside. Ukulawulwa kwale phethini yokusabalalisa okuguquguqukayo okungu-100% kungaba yi-electro-hydraulic, hydro-mechanical, noma ngisho no-100% kagesi. Inkinga ukuthi lezi zinhlelo zandisa ukwanda kanye / noma azithandi kakhulu izindlela eziphakeme, okufana nomzamo omkhulu. Ngamafuphi, ngesikhathi se-titanium valves ezinjini zethu zesithuthuthu, lolu hlobo lokusabalalisa okuguquguqukayo alukakanyakazi ... NB, Lolu hlobo lokusabalalisa okuguquguqukayo luhlukile ku-VTEC Honda, i-DVT Ducati noma i-VVT Kawasaki.

Okuhlinzekwa yi-APAV

Isimiso siwukulawula ingxenye yokudlula yepayipi ngokusondela noma ukususa i-airfoil kude nepayipi lokungena. Ukuze sibe nesimo esihle, singakhuluma ngeqanda noma ngethonsi lamanzi. Uma usuka ku-airfoil, isigaba sikhulu, siseduze, amagesi amaningi avaliwe. Eyokuqala ukuthi emithwalweni ephansi kakhulu (ukunciphisa kanye nezimbobo ezincane), esikhundleni sokuphazamisa ukugeleza, iqondiswe nge-peripherally overspeed emaphethelweni omzila. Njengoba i-injector ifakwe ekugcineni kwe-airfoil, ifafaza uphethiloli webhethri ku-axis ye-air duct futhi akukho lutho olufakwe ezindongeni. Ngakho, ukusetshenziswa nokungcola kuyancishiswa. Emithwalweni ephakathi, iphrofayili iyahlehla futhi umgudu uchazwa ngokwengeziwe, okuvumela ukulawula okuhle kwemiphumela ye-acoustic ethanda ukugcwaliswa. Lapho ilayisha ngokugcwele, i-airfoil iyisula ngokuphelele indawo yokungenisa umoya, kodwa ukuba khona kwayo kude kunomthelela ekusheshiseni ngokweqile kwe-throttle valve emnyango wekhoni, kuyilapho ngokuqhubekayo indlela yomoya ihamba kahle ngokuphelele. Umphumela uwukuthuthuka okucace kakhulu ekugcwalisweni kwenjini, okufakazelwa ukwenyuka kwamaphesenti angamadijithi amabili kumandla wamahhashi noma ngisho namashumi amabili nambili !!! Isistimu ihlolwe ngempumelelo ebhentshini enjini ye-4-stroke single-cylinder enevolumu engu-250 cm3 ...

Butterfly Effect.

Ithulwe kubadlali abahlukahlukene ezithuthuthu nasezimotweni, i-APAV ibilokhu ishaya ekhanda ngesipikili, futhi akekho othe umgomo wayo awunandaba. Asiyona imfihlo yonkulunkulu, kodwa izingxoxo ziyaqhubeka ... Khonamanjalo, i-APAV izothatha izinyathelo zayo zokuqala emithambekeni ye-Rhodson 1078 R entsha, esiyethula kuwe. Okusungulwe kwesiFulentshi ngesithuthuthu sesiFulentshi (esinenjini ye-Ducati), asikwazi ukulinda ukubona umphumela futhi sikugcine unolwazi ngenqubekelaphambili!
