IZINJINI YE-CYCLE ESINE-STROKE
Injini yomjikelezo we-four-stroke ithuthukisa ukushaywa kwamandla okukodwa kwezine
ukunyakaza kwe-piston (okubili phezulu nokubili phansi).Lolu hlobo lungase lubonakale lunjalo
kube ukumosha ukunyakaza kanye nezingxenye, ngoba kudinga izingxenye eziningi ezengeziwe.
Nokho, inezinzuzo eziningi, ikakhulukazi izinjini ezinkulu lapho
ukubumbana akuyona into ebaluleke kangako.
Injini ezine-stroke ayinawo umhlanga, futhi ingxube air-fuel
ayidluli ku-crankcase.Esikhundleni salokho, kukhona ama-valve amabili, njengaku
ll, eyodwa evula futhi ivale iphaseji evela ku-carburetor, enye leyo
ivula futhi ivale iphaseji eya ohlelweni lwe-exhaust.Ama-valve ayasebenza
eduze kwe-camshaft, umphini onama-lobe amise okwe-teardrop aphusha ama-valve
evulekile, futhi ngezikhathi ezifanele, vumela iziphethu ukuba ziwavale.I-camshaft
inegiya ekugcineni, elixhunywe ngegiya ku-crankshaft.I
igiya ku-camshaft inamazinyo amaningi ngokuphindwe kabili kunegiya le-crankshaft, ngakho-ke
ukuthi kukho konke ukuphenduka okuphelele kwe-crankshaft, i-camshaft iyaphenduka
180 degrees.Lokhu kusho ukuthi i-valve ngayinye ivula futhi ivale kanye nje phakathi
ama-revolution amabili e-crankshaft, okuyikhona kanye okudingekayo ku-
umjikelezo wemivimbo emine.
Amavalvu kumshini wokugunda utshani onemivimbo emine noma i-snow blower en
gine atholakala block.Lona umklamo wezimoto zakudala, kodwa
ilungele abagundayo nabavuthelayo.Kukhona ama-stroker amane ambalwa
enamavalvu ekhanda lesilinda, idizayini yezimoto ethandwayo, ekhonjiswe ku
l-4.Kulokhu i-'camshaft lobes isunduza phezu kwenduku ende, ebizwa ngokuthi i-pushrod,
ezungeza ingxenye efana ne-see-saw ebizwa ngokuthi i-rocker arm.
