• Видео

Koma chifukwa chiyani tikufanizira njinga zamoto zamitundu yosiyanasiyana, mutha kufunsa. Ngati simunaphunzire luso laukadaulo, mwina munamva (kuyambiranso) kusukulu ya pulayimale kuti injini ya sitiroko iwiri imatha kutulutsa mphamvu zambiri kuposa injini ya sitiroko inayi yakusamuka komweko. Malingaliro onse ndi machitidwe sizosiyana kwambiri - chifukwa pulagi ya spark-stroke imayatsa sitiroko ina iliyonse, koma mu injini ya sitiroko inayi mikwingwirima inayi iliyonse, injini imapanga mphamvu zambiri, ndipo mosavomerezeka makina oyesera amakhala ndi mphamvu yofanana yofanana. 50 "ndi mphamvu".

Chifukwa chake, mukalasi la mpikisano wa E2 enduro, okwera amatha kukwera ndi injini ziwiri kapena zinayi zama sitiroko zomwe zili ndi injini yokwana 250cc. Onani Mu akatswiri a motocross, akalewo anali atatsala pang'ono kutha, koma osati ku enduro, makamaka panthambi zake zopitilira muyeso monga Hell's Gate, Erzberg ndi mpikisano wamkati wamkati. Chifukwa chake musagwere chifukwa chotaya zinyalala!

Kuchokera pamtunda wa maulendo khumi, magalimoto oyesera amagwira ntchito mofananamo, ndipo ngakhale mutayang'ana deta pazithunzi zakunja, zida ndi voliyumu ya tanki yamafuta, ndizofanana ndi tsitsi. Chiwongolero, chitetezo chabwino (cholimba) chamanja, pulagi kumbali ya kumanzere kwa thanki yamafuta, masinthidwe osavuta ndi zida zazing'ono za digito ndizofanana patsitsi. Kusiyanitsa kumawululidwa ndi mtundu wa injini kapena. kutopa - sitiroko iwiri imakhala ndi "nkhono" yopindika, mikwingwirima inayi imakhala ndi chubu chofanana.

Kutulutsa kwakukulu kumapangitsa 4T kukhala yovuta kusuntha pamanja (osadabwitsa kuti imachitidwa kumunda), chifukwa mphikawo uli pafupi kwambiri ndi chogwirira pansi papiko lakumbuyo, komanso wolemera kwambiri. Mukumva ma kilogalamu kale mukamakweza mgalimoto! Ndipo poyendetsa? Tidadzutsa magalimoto ndikumenya (250) ndikudina batani lofiira (450) (injini yama stroke iwiri nthawi zonse imayaka pambuyo pa kugunda koyamba kapena kwachiwiri!) Ndipo kawiri, mahatchi asintha katatu, malingaliro adakwaniritsidwa mwachangu.

Kuyambira ndikusamutsidwa kwakung'ono: Poyerekeza ndi makina amotocross omwe ali ndi mawotchi awiri amtundu womwewo, injini ya EXC imapukutidwa bwino ngakhale pama RPM otsika. Ngakhale malo otsetsereka kwambiri, owoneka ngati osadutsa amatha kukambitsirana pa liwiro lapakati komanso m'magiya achiwiri, koma injiniyo imasowabe kuyankha kwenikweni komanso kuphulika m'derali. Kuti atulutse ma kilowatts onse, amayenera kusinthidwa kukhala mawonekedwe apamwamba, pamene mawonekedwe ndi phokoso la chipikacho zasintha kwambiri - ndiye kuti padzakhala mphamvu zokwanira (koma osati zochuluka kwambiri kwa enduro yodzaza), ndipo ngati tilimbikira. Pakuthamanga kwathunthu, mathamangitsidwe a makina oyesera amafanana.

Ndizodabwitsa kuti ngakhale injiniyo "ikazimitsa" pa liwiro lochepa kwa kanthawi, imadzuka nthawi yomweyo popanda "kugwedeza" ngati kuli kofunikira. Chifukwa cha kulemera kwake kopepuka, kuyimitsidwa kumakhala kolimba kwambiri, kotero kumafunikira mphamvu yochulukirapo m'manja, makamaka podutsa mabampu afupiafupi otsatizana komwe sikukhazikika kuposa mtundu wa 450cc. Kupereka mphamvu mosagwirizana, kusasunthika koyenda bwino komanso kuyimitsidwa kolimba ndizomwe zimapangitsa kuyendetsa galimoto kumatopetsa, koma, kumbali ina, kumakondweretsa ndi kupepuka kwake komanso mawonekedwe aunyamata.

Pafupifupi kamodzinso, voliyumu ndi mpweya mu zikwapu zinayi zikuwonetsedwa mu EXC 450, makamaka momwe mphamvu imasamutsidwira ku gudumu lakumbuyo. Ngakhale kuti sitiroko ziwiri ziyenera kukhala zolondola kwambiri posankha bokosi la gear, 450-tica imakhululukira pano. Izi zidawonekera kwambiri ndikuthamanga kuchokera pakona kupita kulumpha kwautali - nditalowa pakona ndi giya yayikulu kwambiri yokhala ndi injini ya 250cc, ndimayenera kusintha magiya ndikukankhira chopondapo chamafuta mwamphamvu kuti ndidzuke mwachangu, ndikupitilira. galimoto yokhala ndi mphamvu ya injini ya 450 cc. Zinali zokwanira kungotembenuza chotchinga, ndipo injini mosalekeza, koma motsimikiza, inakwera phiri.

Tinali okondwa kuzindikira kuti EXC 450 sinalinso yankhanza, koma yabwino kwa woyendetsa, kotero kuyendetsa, ngakhale tili ndi mphamvu yayikulu, sikufuna khama kwambiri. Injini imayenda bwino kwambiri ndi kuyimitsidwa, komwe kumasinthidwa kotero kuti imanyamula mabampu modekha, komabe yamphamvu mokwanira kuti njinga isasunthike pamavuto ndikupirira motocross kudumpha osagundana kapena kuphulika. Chosangalatsa ndichakuti, malingaliro a Irt ndikuti 450 EXC yokhala ndi kuyimitsanso bwino ndikuchotsa zinthu zopepuka itha kukhala yoyenera kwa okwera ma motocross. Chifukwa chiyani?

Akuti wokwera wamba wamotocross sangathe kuwongolera ndikugwiritsa ntchito bwino motocross 450s, kotero munthu ngati yemwe EXC amapereka ndi kubetcha kwabwinoko. Tsatanetsatane yokhayo yomwe tikufuna kutsutsa ndi kusatetezeka kwa injini. Mwachitsanzo, ngati mukufuna kuyendetsa pakati pa miyala yakuthwa ya Istria pa mpikisano wa Labin, onetsetsani kuti mugula chishango chamoto, chifukwa chimango (chopapatiza) sichimateteza mokwanira. 250 EXC imachita zina mwazowoneka bwino, ndipo injiniyo ndi yaying'ono ndipo chifukwa chake imabisika bwino kuseri kwa chimango, ndipo ndi theka la centimita kupitilira pansi.

Gawo lachiwiri la mayeso, lomwe silinalembedwe muzithunzi za digito ndi mavidiyo chifukwa chosatsatira malamulo oyendetsa galimoto kumalo achilengedwe (izi sizikulimbikitsidwanso kwa inu), zinachitika m'munda. Maret ndi ine anakwera makilomita 130 kudutsa dziko pasanathe maola asanu ndi awiri, amene mwakachetechete injini (ife timayamikira kuti) unatha maola anayi zonse, malinga ndi mita, ndipo anatsimikizira zotsatira za njanji motocross. Chifukwa chake - 450 EXC ndiyothandiza komanso yosunthika, ndipo 250 EXC ndiyosavuta komanso yosavuta.

Mukakhala pakati pa sitima yayikulu yamiyala muyenera kutembenuza pamanja kapena kuthandizira kukweza "mahatchi" kukwera ndi mphamvu yanu ya bulu, kilogalamu iliyonse ndiyabwino, ndipo apa injini yamagetsi iwiri imagwira ngati makina oyenera kwambiri . Komabe, ali ndi ludzu ndipo akufuna mafuta ochulukirapo mwa magawo awiri pa zana kuphatikiza mafuta. Poyamba "cheke" amafuna theka la lita imodzi, ndipo tidayamba kugwiritsa ntchito malita 8 pamakilomita zana, pomwe kugwiritsa ntchito injini yama sitiroko munjira yomweyo kumaima pa malita 5.

Kuyendetsa bwino kwa onse ndi kwabwino, komanso kwabwino kwa 450cc enduro. olimba mofananamo. Inde, ndi izi: kuwonongeka kwa injini ya sitiroko sikunali kwenikweni, kotero mabuleki ndi dzanja la driver zimavutika kwambiri mukamatsika.

Zilonda ziwiri kapena zinayi? Ambiri azikhala osangalala ndi injini yotsika mtengo, yothandiza kwambiri komanso yodalirika, koma osaphonya pa cvajer ngati simusamala kukonzekera mafuta / mafuta osakanikirana komanso magawano amagetsi osagwirizana (kuyankha kwa injini kumatha kusinthidwa posintha akasupe a valavu mu utsi), makamaka ngati mumakonda kudzitsutsa pamalo ovuta. Tikukhulupirira kuti zomwe tapeza komanso chidziwitso chokhudza mtengo wa ntchito zikuthandizani kupanga chisankho. Ndi zosangalatsa zambiri kuchokera enduro olimba!

Choyamba, ndinene kuti patapita nthawi yayitali ndinakwera njinga yamoto ya enduro ndipo ili panjira yamagalimoto. Chofunika kwambiri pamayesowa chinali kufananitsa injini ya sitiroko iwiri ndi sitiroko, chifukwa amapikisana wina ndi mnzake mgulu lomweli, ndipo popeza ndidakwera njinga yamoto yonyamula ma 450cc chaka chatha. KTM ya buku ili. Ndinachita chidwi ndi mphamvu yogawidwa bwino, popeza m'munsi mulibe nkhanza pang'ono, koma ndiyomvera bwino komanso kopindika.

Kuchepetsako kunali kofewa kwambiri pamalingaliro anga komanso pamayendedwe a motocross, koma injini idachita bwino m'maenje ndikufika. Bicycle palokha si vuto, koma m'makona otsekedwa imangokhala yovuta pang'ono kuposa 250. Ndikutsimikiza kuti njinga iyi idzakhala yabwino kwa okwera ma motocross akamayendetsa damping, chifukwa kuyenda mwachangu komanso mosalala sikunditopetse.

Injini yama cubic 250 ya sitiroko idandikhumudwitsa pang'ono. Ndinayesera kuyendetsa pa rpms yayikulu, koma palibe paliponse pomwe panali mphamvu yomwe chilombocho chimayenera kutulutsa. Ulendowu unali wosangalatsa chifukwa njingayo ndiyopepuka motero imakhala yovuta kwambiri, koma yotopetsa kuposa kukwera njinga yamoto ya 450cc. Onani ndikuganiza kuti 250 EXC ndi ya okonda sitiroko omwe ali ndi chidziwitso chambiri chogwiritsa ntchito mphamvuzi muntchito zochepa ndikusangalala ndi kupepuka kwa njinga.

Tiyerekeze kuti ndimadziona ngati wothamanga wa Lamlungu ndipo ndilibe mphamvu zokwanira zolimbana ndi malo ovuta, kotero ndikumva bwino pa injini ya sitiroko zinayi yomwe imakhala yomasuka komanso yosatopa. Komabe, popeza mayendedwe a moyo ndi othamanga kwambiri masiku ano ndipo palibe nthawi yokwanira yaulere, ndipo popeza zovuta zimabweretsa zovuta, ndipo popeza ngakhale malo otsetsereka kwambiri sayenera kukhala osagonjetseka, ndingakonde kusankha (yotsika mtengo!) Njuchi. 'kwa maola awiri aulere pamwezi. Ma pluses ake akuluakulu ndi kupepuka komanso kuwongolera pamunda. Zomwe muyenera kuwonjezera ndikungowonjezera ndalama zoyambira magetsi.

Pali kusiyana. Ndipo ndizabwino. Monga dalaivala wochita masewera olimbitsa thupi, ma stroke anayi a EXC 450 anali oyenera kwa ine chifukwa ndi ocheperako, amapereka mphamvu mosasinthasintha ndipo amakhala omasuka kuyendetsa kuposa EXC 250. Kumbali inayi, EXC 250 ndiyopepuka kwambiri, koma yolimba chifukwa chake kuli bwino kuyendetsa pamalopo ndi zovuta kwambiri, pomwe ma kilogalamu ochepa amakhala ndi gawo lofunikira. Mosiyana ndi injini ya sitiroko inayi, sitiroko iwiri sichedwa kutsika, ndipo ichi ndi chimodzi mwazinthu zomwe ndimavutika kuzizolowera.
