Kusiyanitsa pakati pa injini yama stroke ndi ma stroke anayi

Mvetsetsani kusiyana pakati pa injini ya 2 ndi 4 yamagetsi, muyenera kumvetsetsa kaye momwe ma mota amagwirira ntchito mozungulira.

Chifukwa chake, kuti injini igwire bwino ntchito, kuyaka kuyenera kukhala kwathunthu. Mu injini za 2-stroke ndi 4-stroke, njirayi ili ndi zikwapu zinayi zosiyana zomwe zimagwiritsidwa ntchito ndi ndodo yolumikizira ndi pisitoni m'chipinda choyaka moto. Chomwe chimasiyanitsa injini ziwirizi ndi nthawi yawo yoyatsira. Kuchuluka kwa kuwombera komwe kumawonetsa momwe injini zamaoko awiri kapena sitiroko zinayi zimasinthira mphamvu komanso kuthamanga komwe kumawombera mwachangu.

Kodi injini ya 4-stroke imagwira ntchito bwanji? Kodi pali kusiyana kotani pakati pa injini ya sitiroko iwiri ndi mainjini anayi? Onani mafotokozedwe athu a ntchitoyi komanso kusiyana pakati pa mitundu iwiri ya injini.

4-sitiroko injini

Ma injini a sitiroko anayi ndi ma injini omwe kuyaka kwawo kumayambika ndi gwero lamphamvu lakunja monga spark plug kapena shaker. Kuyaka kwawo kofulumira kwambiri kumasintha mphamvu yamagetsi yomwe ili mumafuta kuti ikhale mphamvu yamakina panthawi ya kuphulika.

Mbali 4-sitiroko injini

Injiniyi ili ndi chimodzi kapena zingapo zonenepa aliyense wa iwo ali ndi pisitoni kutsetsereka ndi zoyenda liniya. Pisitoni iliyonse imakwezedwa ndi kutsitsidwa pogwiritsa ntchito ndodo yolumikizira pisitoniyo ndi crankshaft. Chitsulo chilichonse chomwe chimapanga injini ya 4-stroke chimatsekedwa ndi mutu wamphamvu wokhala ndi mavavu awiri:

• Valavu yodyera yomwe imapatsa silindayo mafuta osakanikirana ndi mpweya kuchokera kuzambiri.
• Vuvu yotulutsa yomwe imapititsa mpweya wakunja kunjaku ndi utsi.

Ntchito yoyendetsa injini ya 4-stroke

Kuthamanga kwa injini ya 4-stroke kudasokonekera injini zinayi zamagetsi. Nthawi yoyamba ndi yomwe imapanga mphamvu. Iyi ndi nthawi yomwe kuyaka kwa chisakanizo cha mafuta ndi mpweya kumayambitsa kayendedwe ka pisitoni. Chotsatiracho chimayamba kusuntha panthawi yoyambira mpaka injini imodzi yamtunduwu yatulutsa mphamvu yofunikira kuti ipereke nthawi zina zitatu zogwiritsira ntchito mphamvu injini isanayambe. Kuyambira nthawi imeneyo, injini imadziyendetsa yokha.

Gawo 1: mpikisano woyambira

Kusuntha koyamba kopangidwa ndi injini ya 4-stroke kumatchedwa: "polowera". Ichi ndi chiyambi cha ntchito ya injini, chifukwa chake pisitoni imatsika koyamba. Pisitoni wotsika amatulutsa mpweya motero mafuta ndi mpweya zimalowa mchipinda choyaka moto kudzera pa valavu yodyera. Poyambitsa, mota yoyambira yomwe imalumikizidwa ndi flywheel imasunthira chopingasa, ndikuyendetsa silinda iliyonse ndikupereka mphamvu zofunikira kuti amalize kupwetekedwa.

Gawo lachiwiri: kuponderezana

Kuponderezana imachitika pisitoni ikakwera. Valavu yodyedwa itatsekedwa panthawiyi, mafuta ndi mpweya zimakanikizika mchipinda choyaka moto mpaka 30 bar ndi 400 ndi 500 ° C.

Gawo 3: moto kapena kuphulika

Pisitoni ikakwera ndikufika pamwamba pamiyeso, kupanikizika kumakhala kokwanira. Pulagi yolumikizidwa ndi jenereta yamagetsi yayikulu imayatsa mpweya wopanikizika. Kutentha kapena kuphulika komwe kumachitika pambuyo pa bala 40 mpaka 60 kumakankhira pisitoniyo pansi ndikuyambitsa kuyenda kwakanthawi.

4 sitiroko: utsi

Utsi umatha kumaliza kuyaka kwamiyendo inayi. Pisitoni imakwezedwa ndi ndodo yolumikizira ndikukankhira mpweya wopsereka kunja. Valavu yotulutsa utsi imatsegulidwa kuti ichotse mpweya wowotcha kuchokera m'chipinda choyaka moto kuti ipange mpweya watsopano / mafuta osakaniza.

Kodi pali kusiyana kotani pakati pa injini za 4-stroke ndi injini za 2-stroke?

Mosiyana ndi 4-sitiroko injini, 2-sitiroko injini gwiritsani ntchito mbali zonse ziwiri - pamwamba ndi pansi - za pistoni... Yoyamba ndiyoponderezana ndi magawo oyaka. Ndipo chachiwiri ndikutumiza kwa mpweya wambiri komanso utsi. Popewa mayendedwe azigawo ziwiri zamagetsi, amapanga makokedwe ndi mphamvu zambiri.

Magawo anayi pagulu limodzi

Mu injini yama stroke, moto umabula kamodzi pakasintha. Magawo anayi azakudya, kuponderezana, kuyaka ndi utsi amachitika mozungulira kamodzi kuchokera pamwamba mpaka pansi, chifukwa chake dzina loti stroko awiri.

Palibe valavu

Popeza kudya ndi utsi ndi gawo limodzi la kuponderezana ndi kuyaka kwa pisitoni, ma injini awiri opunthira alibe valavu. Zipinda zawo zoyaka moto zimakhala ndi malo ogulitsira.

Mafuta osakaniza ndi mafuta

Mosiyana ndi injini za 4-stroke, injini za 2-stroke zilibe zipinda ziwiri zapadera za mafuta ndi mafuta. Zonsezi zimasakanizidwa m'chipinda chimodzi mofanana.
