IZINJINI YOMJIKELO EZINE-STROKE
I-injini ye-four-stroke cycle iphuhlisa istrowukhi yamandla enye kuzo ezine
iintshukumo zepiston (ezimbini phezulu kunye ezimbini phantsi).Olu hlobo lunokubonakala ngathi
ibe yinkcitho yentshukumo kunye namalungu, kuba ifuna iindawo ezininzi ngakumbi.
Nangona kunjalo, ineenzuzo ezininzi, ngakumbi kwiinjini ezinkulu apho
ukubumbana akuyonto ibalulekileyo.
I-injini ezine-stroke ayinayo ingcongolo, kunye nomxube we-air-fuel
ayidluli kwikhrankcase.Endaweni yoko, kukho iivalve ezimbini, njengaku
ll, enye evula kwaye ivale isicatshulwa kwi-carburetor, enye leyo
ivula kwaye ivale indlela eya kwi-exhaust system.Iivalvu ziyasebenza
ngakwicamshaft, ishafti enemilo emile ye-teardrop etyhala iivalvu
vula, kwaye ngamaxesha afanelekileyo, vumela imithombo ukuba ivale.Icamshaft
inegiya kwelinye icala, edibanisa igiya kwi-crankshaft.I
izixhobo kwi-camshaft inamazinyo amaninzi ngokuphindwe kabini njengegiya ye-crankshaft, ngoko
ukuba kulo lonke ujikelezo olupheleleyo lwecrankshaft, icamshaft iyajika
180 degrees.Oku kuthetha ukuba ivalve nganye iyavula kwaye ivale kube kanye ngexesha
ii revolutions ezimbini crankshaft, nto leyo kanye efunekayo ukuze a
umjikelo ezine-stroke.
Iivalvu kumatshini wokucheba ingca okanye umvutheli wekhephu eqhelekileyo
gine zibekwe kwibhloko.Olu luyilo lweemoto zakudala, kodwa
ilungile ngokwaneleyo kwizitshizi kunye neefutha.Kukho ezimbalwa ezine-stroker
ngeevalvu kwintloko yesilinda, uyilo oludumileyo lweemoto, oluboniswe kwi
l-4.Kule meko i-'camshaft lobes ityhala kwintonga ende, ebizwa ngokuba yi-pushrod,
ejikeleza indawo efana ne-see-saw ebizwa ngokuba yi-rocker arm.
