Kuyinto eqhelekileyo ukuba umbhobho wokukhupha wenze isandi esirabhayo emva kokuba injini ivaliwe.Umbhobho wokukhupha ushushu kakhulu xa injini isebenza kwaye iya kwanda xa ishushu.Le ngxolo iya kubangelwa xa iqondo lobushushu liyehla emva kokuba injini icinyiwe.Ukuba kukho idiphozithi yekhabhoni encinci kumbhobho wokukhupha imoto entsha, isandi siya kucaca kwaye sicace ngakumbi, esiqhelekileyo.

Isithuthuthu, isithuthi esinamavili amabini okanye amathathu esiqhutywa yinjini yepetroli kwaye siqhutywa sisiphatho, silula, sibhetyebhetye kwaye siyakhawuleza.Isetyenziswa ngokubanzi ukujikeleza, ukuthutha abakhweli kunye nempahla, kunye nezixhobo zemidlalo.

Thatha umgaqo osebenzayo we-injini ye-stroke emine kunye ne-injini ye-stroke ezimbini njengomzekelo: injini ye-stroke emine isetyenziswa ngokubanzi.I-injini ye-stroke emine ithetha ukuba i-cylinder ivutha kanye kwiintshukumo ezine eziphindaphindayo zepiston.Umgaqo-nkqubo othile wokusebenza ngolu hlobo lulandelayo:

Ukungena: Ngeli xesha, ivalve yokungena iyavuleka, ipiston ihle ijonge ezantsi, kwaye umxube wepetroli nomoya ufunxeka kwicylinder.

Ukunyanzeliswa: ngeli xesha, i-valve yokungena kunye ne-valve yokukhupha ivaliwe ngexesha elifanayo, i-piston ihambela phezulu, kwaye umxube uxinzelelwe.

Ukutsha: xa i-mixer icinezelwe ukuya kubuncinci, iplagi ye-spark iya kuxhuma kwaye ivuthe igesi edibeneyo, kwaye uxinzelelo oluveliswa ngokutshisa luya kutyhala ipiston phantsi kwaye iqhube i-crankshaft ukuba ijikeleze.

Ukukhupha: Xa ipiston yehla ukuya kwindawo ephantsi, ivalve yokukhupha iyavula, kwaye igesi yokukhupha ikhutshwa.Ipiston iyaqhubeka nokunyuka ukukhupha irhasi ephumayo.

Umgaqo osebenzayo we-injini ye-stroke ezimbini kukuba i-piston ihla inyuka kwaye ihle imivumbo emibini kwaye i-spark plug ivutha kanye.Inkqubo yokuthatha i-injini ye-stroke yesibini yahluke ngokupheleleyo kuleyo ye-injini yesine ye-stroke.I-injini ye-stroke ezimbini kufuneka ixinzelelwe kabini.Kwi-injini ye-stroke yesibini, umxube uqukuqela ungene kwi-crankcase kuqala uze ungene kwi-cylinder.Ngokukodwa, igeleza kwigumbi lokutsha, ngelixa umxube we-injini ye-stroke yesine ihamba ngokuthe ngqo kwi-cylinder.I-crankcase ye-injini ye-stroke yesine isetyenziselwa ukugcina i-oyile, Njengoko i-crankcase ye-injini ye-stroke ezimbini isetyenziselwa ukugcina i-gas exutywe kwaye ayikwazi ukugcina i-oyile, i-oyile esetyenziselwa i-injini ye-stroke e-tbini i-oyile yokutsha engenakuphinda isetyenziswe.

Inkqubo yokusebenza ye-injini ye-stroke yesibini imi ngolu hlobo lulandelayo:

Ipiston ihambela phezulu kwaye umoya oxubeneyo uqukuqela ungene kwi-crankcase.

I-piston yehla ukuhambisa uxinzelelo lomoya odibeneyo kwigumbi lokutsha, ukugqiba ukunyanzeliswa kokuqala.

Emva kokuba umxube ufikelele kwi-cylinder, ipiston iya phezulu kwaye ivale i-inlet kunye ne-outlet.Xa i-piston ixinzelela igesi kumthamo omncinci (oku kukunyanzeliswa kwesibini), i-spark plug ivutha.

Uxinzelelo lokutsha lutyhala ipiston phantsi.Xa i-piston ihla ukuya kwindawo ethile, i-port exhaust ivulwa kuqala, kwaye igesi yokukhupha ikhutshwe kwaye emva koko i-air inlet ivuliwe.Irhasi entsha exubeneyo ingena kwisilinda ukuze ikhuphe irhasi yokukhupha eseleyo.
