Masilinda atatu

Bwanji ngati inali njinga yamoto ENGINE par kupambana?

M'mbuyomu tidadziwa 3-cylinder 2-stroke, pa intaneti pa Kawasaki, Suzuki ndi Motobécane, kapena mawonekedwe a V pa Honda. Ndipotu, kwa Honda, awa anali injini liniya, zonenepa amene anazanditsidwa kupeza m'lifupi. Panali ndodo imodzi yokha yolumikizira pa manequin, ndipo silinda iliyonse inali ndi chotengera chake chodziyimira payokha. Ma injini awa anali ndi ma PSA 400 amsewu ndi 500 RS ndi NS GPs. Tsatanetsatane woseketsa, masanjidwe omwe adagwiritsidwa ntchito adatembenuzidwa: masilinda 2 opingasa ndi oyimirira pamsewu, mosiyana ndi GP. Mwinanso pazinthu zokhudzana ndi ndime ya miphika yopumula komanso kutentha komwe kumatulutsidwa ...

Mwachidule, injini zamasilinda atatu masiku ano ndi injini zomwe zili ndi mphepo m'matanga awo, koma onse ali ndi zomangamanga zofanana: injini yapakatikati komanso yozungulira 4-stroke, chifukwa sitiroko iwiri ilibenso mphepo. mayendedwe ake ...

Mmodzi kwa onse, onse pa intaneti!

Kuti ma calibration mulingo woyenera pa kugwedera ndi cyclical wokhazikika, crankcase pabwino aliyense 120 ° ntchito pafupipafupi, kuwotcha aliyense 240 ° (kutembenukira kumodzi / 2). Mu 70s / 80s Laverda anamasulidwa 180 ° atatu yamphamvu 1000, injini amene anali kwambiri "khalidwe" kuposa Mabaibulo amene anatsatira 120 °. Galimoto iyi, yotchedwa "Jota" pambuyo pa imodzi mu Spanish-stroke itatu, imakhalabe yosiyana.

4-sitiroko atatu silinda mu GP

Injini yamasilinda atatu idachitanso bwino kwambiri mu GP, koyamba pamasitepe anayi, munthawi yaulemerero ya MV Agusta, kenako masitepe awiri. Zakale zake ndi zaulemerero kwambiri moti ngakhale lero 4 F2 ndi ya MV800 3 yotchuka (3) ndi 350 (1965). 500 adapanga pafupifupi 1966 hp. pa 500 rpm ndi kupitirira 80 Km / h. Adapambana maudindo osachepera 12 padziko lonse lapansi pakati pa 000 ndi 270 m'manja mwa Giacomo Agostini! Ngati makina enieni atenga kamangidwe kameneka, mainjini amakono amakhala ndi crankshaft yozungulira yomwe imachepetsa mphamvu ya njinga yamoto ndikupangitsa kuti ikhale yamphamvu.

Posachedwapa tidawonanso GP yamasilinda atatu panthawi yokweza mpaka anayi. Mu 2003, komabe, anabisala ngati Aprilia Cube, zinali zochepa kwambiri kuposa VM. M'malo mwake, makinawa amaphatikiza kuchepa kwapang'onopang'ono komanso kuthekera kosinthana kusinthana motero kumapanga mphamvu zenizeni zenizeni. "Mwachidule" mwina ndi gawo lavuto la Cuba, chifukwa tsopano muyenera kuthamanga kwambiri kuti mukakamize GP wanu.

Mitundu yosagwirizana ndi zomanga zomwe sizimagawanitsa mokwanira kusamuka. Izi zimalanga mathamangitsidwe a pistoni, monga tidzakambirana mtsogolo. Ndi nthiti za 88,6 X 53,5 "zolengezedwa", kyubuyo inavutika kuti ipitirire 15 rpm. Zakudya ndizochepa kwambiri, zokhala ndi zopapatiza. Chotsatira chake chinali injini yankhanza yomwe inkalepheretsa kugwira komanso kuyendetsa bwino.

Kufanana

Pachifukwa ichi, m'gulu la supersport, monga SBK, ma silinda atatu apeza mwayi pazitsulo za 4. Chifukwa chake tidawona kugunda kwa 675 cc kwa masilindala atatu a MV ndi Kupambana motsutsana ndi silinda ya 3 cc 600. Mu SBK pa 3 4-silinda, 750 atatu yamphamvu ndi 4 amapasa yamphamvu. Izi zinapangitsa Petronas kugwiritsa ntchito 900 yosangalatsa yokhala ndi injini yopindika: inverted (utsi kumbuyo, khomo lakutsogolo ndi masilindala opendekera kumbuyo). Chitsanzo chabwino cha "miyendo itatu".

Lamulo la kupirira ndi 600 masilindala anayi, koma ma cylinders atatu m'pofunika kupitirira 750 cm3. Kusiyana sikunapezeke mu GP, makamaka masiku ano, pamene malamulo anapereka munthu pazipita masilindala 4 ndi anabowola zosaposa 81mm. Ndipotu, miyeso ya atatu yamphamvu GP, chosinthika bwino, adzakhala 81 X 48,5 mm kapena pazipita liwiro pafupifupi 17 rpm pa pisitoni liniya liwiro la 000 m / s. Kuphatikiza pa kukwera pamahatchi, mwina pang'ono chilungamo, pali kuvala kofulumira kwambiri, kosagwirizana ndi kuchuluka kwa injini zololedwa panyengo iliyonse. Chifukwa chake, kupatula kuyang'ana zovuta, palibe amene abwereke ma silinda atatu mpaka atadziwitsidwanso.

Yaing'ono koma yamphamvu

Pankhani ya mpikisano wamsewu ndi masewera, katatu amanyalanyaza izi. Amasewera ndi compactness wake (800 MW yekha akulemera 52 kg!) Kutumikira njinga zamoto kuti nthawi zonse zosangalatsa kwambiri chifukwa ikukonzekera ake, amene amamupatsa kuyankha kosangalatsa throttle ndi kukhalapo kwenikweni. Izi zikuwonetseredwa ndi mapindikidwe a buku lodziwika bwino la injini. Choyamba, timazindikira makokedwe anthawi yomweyo a injini ya 1616cc (3 X 3cc) yamasilinda atatu.

Pali nsonga pa 603 Nm, pamene pamapindikira lotsatira ma silinda 4 2155 (4 X 538 cm3), amene komabe kukhala apamwamba pafupifupi makokedwe (180 Nm motsutsana 135), ndi 425 Nm yekha torque yomweyo pazipita. !

Mwachidule, ndi kusuntha kochepa komanso kutsika kwapakati, nsonga zamakokedwe amtundu wachitatu nthawi yomweyo zimakhala zapamwamba kwambiri kuposa injini ya 4-cylinder, zomwe zikutanthauza kukondwa kwambiri kwa woyendetsa.

Pomaliza

Kaya ndi phiri la trail, roadster kapena sports car mount, ndi injini yokongola yomwe ndi yaying'ono komanso yopepuka kuposa ma silinda anayi. Makhalidwe amene amamulonjeza tsogolo lowala pa mawilo awiri kapena anayi. Inde, pang'onopang'ono imayikidwanso pansi pa hoods magalimoto amakono mu Mabaibulo ndi supercharging 1000 kapena 1200 cm3. Mosakayikira, sanamalize kutidabwitsa!
