Cov khoom siv sij hawm sib txuas yog ib qho ua tiav ntawm cov khoom tseem ceeb hauv lub cav tsheb siv los xyuas kom meej qhov kev ua haujlwm ntawm lub tsheb ciav hlau valve. Nws lub luag haujlwm tseem ceeb yog los tswj cov kev sib hloov ntawm lub crankshaft thiab camshaft, kom ntseeg tau tias txhua lub tog raj kheej ua tiav kev noj thiab tso pa thaum lub sijhawm raug, yog li tswj xyuas lub cav kom ua haujlwm tau zoo thiab ruaj khov.
Cov khoom siv no feem ntau suav nrog cov hauv qab no tseem ceeb:
Lub Sijhawm Chain: Cov qauv hlau txuas txuas nrog lub crankshaft thiab camshaft. Nws yog qhov ruaj khov dua thiab muaj lub neej ntev dua li lub sijhawm siv, thiab feem ntau tsis tas yuav hloov pauv.
Tensioner thiab Tensioner Rail: Siv los tswj cov saw hlau kom zoo, tiv thaiv cov hniav hla los yog hnav vim xoob. Feem ntau hydraulic tsim, lawv yuav muaj hnub nyoog dhau sijhawm.
Phau Ntawv Qhia Rails thiab Daim Ntawv Qhia: Qhia cov saw hlau kom khiav zoo, tiv thaiv kev sib txawv lossis kev swb. Qee cov qauv muaj cov ntawv qhia ntawm ob sab lossis hauv nruab nrab ntawm cov saw hlau los txhim kho kev ruaj ntseg.
Lub Sijhawm Sprockets (Camshaft Sprockets, Crankshaft Sprockets): Raws li cov khoom siv rau kev xa hluav taws xob, lawv mesh nrog cov saw kom paub meej cov iav sib piv.
Cov khoom siv sib txuam: xws li bolts, ntxhua khaub ncaws, baffles thiab lwm yam me me uas yooj yim puas, nws raug nquahu kom hloov lawv ua ke thaum kho kom tsis txhob muaj qhov qub los ntawm kev cuam tshuam tag nrho kev ua haujlwm.
