Zonke iibrashi zokusika, iimower, izivuthelo kunye neesarha ezisebenza ngerhasi zisebenzisa i-injini yepiston efanayo ngemibandela ebalulekileyo naleyo isetyenziswa kwiimoto.Kukho iiyantlukwano, nangona kunjalo, ngokukodwa ekusebenziseni iinjini zemijikelo emibini kwiisarha zamakhonkco kunye nengca yengca.
Ngoku Masiqale ekuqaleni kwaye sibone indlela iinjini ezinemijikelo emibini kunye nezinye eziqhelekileyo ezisebenza ngayo.Oku kuya kukunceda kakhulu ukuba uqonde ukuba kwenzeka ntoni xa injini ingasebenzi.
I-injini iphuhlisa amandla ngokutshisa umxube wepetroli nomoya kwindawo ebiyelweyo encinci ebizwa ngokuba ligumbi lokutsha, ebonisa emfanekisweni.Njengoko umxube uvutha amafutha, ushushu kakhulu kwaye uyanda, kanye njengokuba imekyuri kwithemometha isanda kwaye ityhala inyuka kwityhubhu xa ubushushu bayo bunyuka.
Igumbi lokutsha livalwe kumacala amathathu, ngoko ke umxube werhasi owandisiweyo unokutyhala indlela yawo kwicala elinye kuphela, ezantsi kwiplagi ebizwa ngokuba yipiston-enesilayidi esisondeleyo.Ukutyhala ezantsi kwipiston ngamandla omatshini.Xa sinamandla ajikelezayo, sinokujika ibrush cutter blade, isarha yamatsheyini, iauger yokuvuthela ikhephu, okanye amavili emoto.
Ekuguquleni, i-piston ifakwe kwi-crankshaft, ethi ifakwe kwi-crankshaft kunye namacandelo e-offset.I-crankshaft isebenza njengeepedals kunye ne-main sprocket kwibhayisekile.
Xa unyoba ibhayisekile, uxinzelelo olusezantsi lonyawo lwakho kwi-pedal luguqulwa lube yintshukumo ejikelezayo nge-pedal shaft.Uxinzelelo lwenyawo lwakho lufana namandla enziwe ngumxube ovuthayo wamafutha.I-pedal yenza umsebenzi wepiston kunye nentonga yokudibanisa, kwaye i-pedal shaft ilingana ne-crankshaft.Indawo yentsimbi apho umbhobho ubhorekile ibizwa ngokuba yi-injini block, kwaye icandelo elingezantsi apho i-crankshaft inyuswe khona ibizwa ngokuba yi-crankcase.Igumbi lokutsha eliphezu kwe-cylinder lenziwe kwikhava yesinyithi ye-cylinder, ebizwa ngokuba yi-cylinder head.
Njengoko ipiston yokudibanisa intonga inyanzelwa ukuba ihle, kwaye ityhala kwi-crankshaft, kufuneka ijike iye phambili naphambili.Ukuvumela le ntshukumo, intonga ixhonywe kwiibheringi, enye kwipiston, enye kwindawo yokudibanisa kwi-crankshaft.Kukho iintlobo ezininzi zeebheringi, kodwa kuzo zonke iimeko umsebenzi wabo kukuxhasa naluphi na uhlobo lwenxalenye eshukumayo ephantsi komthwalo.Kwimeko yentonga yokudibanisa, umthwalo uvela kwipiston ehamba phantsi.Ibhere ingqukuva kwaye igudile kakhulu, kwaye indawo ejongene nayo kufuneka igudiswe.Ukudityaniswa kweendawo ezigudileyo akwanelanga ukuphelisa ukungqubana, ngoko ke ioyile kufuneka ikwazi ukungena phakathi kokuthwala kunye nenxalenye eyixhasayo ekunciphiseni ukungqubana.Olona hlobo luqhelekileyo lokuthwala luyilo olucacileyo, umsesane ogudileyo okanye mhlawumbi iigobolondo ezimbini ezinesiqingatha ezenza isangqa esipheleleyo, njengakwill.
Nangona amalungu adityanisiweyo adityaniswe ngoomatshini ngononophelo ukuze alingane, ukwenza oomatshini kukodwa akwanelanga.Kufuneka kubekwe isitywina phakathi kwazo ukuthintela ukuvuza komoya, amafutha okanye i-oyile.Xa itywina sisiqhekeza esisicaba semathiriyeli, ibizwa ngokuba yigasket.Izinto eziqhelekileyo ze-gasket ziquka irabha yokwenziwa, i-cork, i-fiber, i-asbestos, isinyithi esithambileyo kunye neendibaniselwano zezi.I-gasket, umzekelo, isetyenziswe phakathi kwentloko ye-cylinder kunye ne-injini block.Ngokufanelekileyo, ibizwa ngokuba yi-cylinder head gasket.
Ngoku makhe siqwalasele ngokuthe ngqo ukusebenza kwe-injini yepetroli, enokuthi ibe yezi ntlobo zimbini: umjikelo we-stroke ezimbini okanye ezine-stroke.
