Txhawm rau kom muaj kev nyab xeeb, kev ntseeg tau thiab kev ua haujlwm ntawm cov hlua khi hauv tsheb, kev lag luam tsheb ua raws cov qauv nruj thiab cov kev cai. Cov koom haum xws li SAE thiab ISO tau teeb tsa cov txheej txheem rau txhua yam ntawm cov hlua hlau tsim los ntawm cov ntsuas hluav taws xob thiab cov khoom sib txuas rau cov xaim ntev thiab cov khoom siv rwb thaiv tsev.
Cov qauv no txo qhov kev pheej hmoo ntawm hluav taws xob hluav taws xob, txo qhov cuam tshuam ntawm kev vibration thiab hnyav ib puag ncig thiab lav qhov zoo ib yam thoob plaws txhua txoj hlua. Piv txwv li, cov kev cai hais txog yuav ua li cas cov xov hlau yuav tsum tau hla thiab ruaj ntseg, cov connectors siv dab tsi, thiab cov txheej txheem ntsuas dab tsi los xyuas qhov tseeb ntawm hluav taws xob. Los ntawm kev ua raws li cov lus qhia no, cov tuam txhab tsim khoom tuaj yeem ua kom ntseeg tau tias txhua txoj hlua hluav taws xob ua tau raws li cov qauv ntsuas zoo thiab ua tau raws li qhov xav tau ntawm cov tsheb niaj hnub no. Kev ua raws cai tsis yog tsuas yog kev cai lij choj nkaus xwb tab sis kuj yog qhov tseem ceeb hauv kev txo qis kev pheej hmoo thiab kev ntseeg siab ntawm cov neeg siv khoom.
