250 4T kapena 2T injini - ndi injini ya 250cc yomwe mungasankhe panjinga yamoto?

Nkhani yofunikira pakusankha gawo ngati injini ya 250 4T kapena 2T ndi momwe zilili komanso momwe wogwiritsa ntchito mtsogolo adzakwera njinga yamoto. Kodi mudzakhala mukuyendetsa m'misewu yokonzedwa bwino kapena kuyendetsa galimoto movutikira, monga mumsewu waukulu kapena m'nkhalango? Timapereka chidziwitso chofunikira kwambiri chomwe chingakuthandizeni kupanga chisankho choyenera.

Kodi injini ya 250cc imakhala ndi mphamvu zotani?

Kugwirizana kwachindunji pakati pa mphamvu ndi mayunitsi amtundu wa 250. Ayi. cm³. Izi zili choncho chifukwa kuyeza kwa mphamvu kumadalira zinthu zambiri. Komabe, tikhoza kunena kuti nthawi zambiri zimakhala pakati pa 15 mpaka 16 hp.

250 4T injini - zambiri zofunika

Ma injini a 250 4T ali ndi mphamvu zambiri komanso zosavuta kuzigwiritsa ntchito. Iwo ndi njira yabwino kwa mawilo awiri okhala ndi injini zamphamvu za 2T. Mphamvu yapamwamba imatha kukhala yokwera kwambiri ndi mtundu wa 2T, koma imatha kukhala yosakhazikika ndikugwiritsa ntchito nthawi yayitali. Posankha 250 4T injini, simungadandaule za mbali imeneyi, komanso mfundo yakuti unit adzalephera mu zinthu zovuta, pamene msewu poterera ndipo pali potholes.

Mtundu uwu wa injini umapereka mphamvu zazikulu, makamaka mumtundu wapamwamba wa rev. Njinga zamoto zomwe zili ndi chipangizochi zimathanso kuona malo otsika a mphamvu yokoka. Amakhalanso opepuka kuposa zikwapu zinayi komanso zotsika mtengo. 

Mutha kuzindikiranso kuti kukokera sikukhala bwino nthawi zonse ngati injini ya 250 4T, makamaka pamalo oterera. Izi, nazonso, zitha kulipidwa ndi mphamvu yayikulu yomwe unityo imapanga.

Ndi injini ziti za 250cc 4T i2T zomwe ndiyenera kuyang'ana?

Pankhani ya injini ya 250cc 2T, enduro ikhoza kukhala chisankho chabwino. Mawilo awiri oyenera kuyang'ana ndi Husqvarna TE yokhala ndi injini ya 250cc 2T. Chigawo cha sitiroko ziwiri chili ndi voliyumu yogwira ntchito ya 249 cm³ ndi ma liwiro asanu ndi limodzi.

Mapangidwe a galimoto amapangidwa m'njira yochepetsera kulemera ndi miyeso. Ili ndi kuyimitsidwa kosinthika kwa Marzocchi kutsogolo ndi Sachs kumbuyo. Jekeseni wamafuta adagwiritsidwanso ntchito, chifukwa chomwe kuwongolera kwa injini kunakula kwambiri.

Yamaha YZ250F

Chimodzi mwazinthu zosangalatsa kwambiri zoperekedwa ndi masitolo a njinga zamoto ndi Yamaha YZ250F. Njinga yamotocross iyi yakhala ikupanga kuyambira 2001. Mtundu woyamba unali ndi injini yoziziritsa madzi ya DOHC yokhala ndi mavavu asanu, yokhala ndi 39 hp. Anali ndi gearbox ya 5 speed.

makina amatamandidwa kaphatikizidwe lonse powerband injini zinayi sitiroko mosavuta ntchito mofanana ngakhale zitsanzo ndi ang'onoang'ono injini 125. cm³. Okonza ku Japan akwaniritsa izi pophatikiza chimango chachikulu chachitsulo ndi chothandizira cha aluminiyamu. 

Kukweza kwina kunachitika m'zaka zotsatira. Mu 2010, injini yatsopano yokhala ndi malo otsika yokoka idakhazikitsidwa, mu 2014 silinda yakumbuyo yokhala ndi mutu wa ma valve anayi ndi jakisoni wamafuta, ndipo mu 2019 choyambira chamagetsi.

Hero M25 

Mtundu wa Junak umagawira chitsanzo choyambirira cha njinga yamoto, chomwe chimakumbukira Harley mu zomangamanga zake. Ili ndi injini yolimba ya 250 4T. Mawilo awiri azigwira ntchito bwino panjira zazitali. Mphamvu wagawo anaika pa njinga yamoto mphamvu yeniyeni ya 249 cm3. Iyi ndi injini ya 18,8 hp yamadzi yoziziritsidwa ndi sitiroko anayi.

Kulemera okwana makina ndi 153 makilogalamu. Okonzawo adayikanso ma disk brakes kutsogolo ndi kumbuyo. Anthu awiri amatha kuyenda panjinga ya matayala awiri ya Junak M25 nthawi imodzi. Mtengo umakondweretsanso. Mtunduwu ungagulidwe pamtengo wochepera ma ruble 10. zloti.

Kodi 250cc unit ingayikidwe pagalimoto ina osati njinga yamoto?

• 3-mawilo (trike);
• 4-mawilo (okhala anayi);
• 6 kapena 8 mawilo;
• yokhala ndi gudumu lakumbuyo;
