Nws puas tuaj yeem sib xyaw cov roj cav ntawm cov tuam txhab sib txawv, hom, viscosity
Cov lus nug ntawm qhov muaj peev xwm ntawm kev sib xyaw cov roj twj tso kua mis tas li txhawj xeeb rau cov neeg tsav tsheb, tshwj xeeb tshaj yog tias cov qib poob qis vim qhov xau, thiab koj tseem yuav tau mus thiab mus rau lub tuam txhab khw muag khoom lossis kev pabcuam ze tshaj plaws.
Hauv ntau cov ntaub ntawv, koj tuaj yeem nrhiav ntau cov ntaub ntawv hais txog kev sib xyaw cov roj cav, thiab tsis muaj ib qho kev xav ntawm qhov teeb meem no: ib txhia hais tias nws ua tau, lwm tus hais tias nws tsis yog. Cia peb sim ua kom paub nws ntawm peb tus kheej.
Raws li koj paub, lub cev muaj zog roj rau lub tsheb tau muab faib ua ntau hom:
- yooj yim puag - "mineral dej", synthetics, semi-synthetics;
- degree ntawm viscosity (SAE) - muaj cov npe ntawm 0W-60 txog 15W-40;
- Kev faib tawm raws li API, ACEA, ILSAC - rau hom cav twg nws yog npaj - roj av, diesel, plaub- lossis ob-mob stroke, kev lag luam, tsheb thauj khoom, tsheb, thiab lwm yam.
Raws li txoj cai, cov roj tshiab uas los ntawm kev ua lag luam mus dhau los ntawm kev sib tw ua ke nrog lwm cov roj. Yuav kom tau txais daim ntawv pov thawj rau ntau yam kev faib tawm, cov roj yuav tsum tsis txhob muaj cov khoom siv ntxiv thiab cov khoom siv ntxiv uas yuav cuam tshuam nrog cov khoom siv ntxiv thiab lub hauv paus ntawm qee cov "kev siv" hom roj. Nws kuj tseem raug kuaj xyuas seb "phooj ywg" cov khoom siv roj nplua nyeem yog li cas rau cov khoom siv cav - hlau, roj hmab thiab cov kav hlau, thiab lwm yam.
Ntawd yog, hauv txoj kev xav, yog cov roj los ntawm cov tuam txhab sib txawv, xws li Castrol thiab Mobil, koom nrog tib chav kawm - hluavtaws, semi-synthetics, muaj tib qib viscosity - 5W-30 lossis 10W-40, thiab tsim los rau tib hom cav, ces koj tuaj yeem sib tov lawv.
Tab sis nws raug nquahu kom ua qhov no tsuas yog thaum muaj xwm txheej ceev, thaum kuaj pom qhov xau, cov roj ntws tawm sai sai, thiab koj tsis tuaj yeem yuav "cov roj haiv neeg" nyob ze.
Yog tias koj tau ua qhov kev hloov pauv no, koj yuav tsum tau mus rau qhov kev pabcuam sai li sai tau thiab tom qab ntawd yaug lub cav kom huv si tag nrho cov khoom ntawm slag, nplai thiab hlawv thiab sau cov roj los ntawm ib lub chaw tsim khoom. Tsis tas li ntawd, thaum tsav tsheb nrog xws li "cocktail" hauv lub cav, koj yuav tsum xaiv hom kev tsav tsheb maj mam, tsis txhob overload lub cav.
Yog li, nws raug tso cai los sib xyaw cov roj ntawm cov khoom sib txawv nrog cov yam ntxwv zoo ib yam, tab sis tsuas yog txhawm rau kom tsis txhob nthuav tawm lub cav kom muaj kev ua haujlwm tsis zoo uas yuav tshwm sim thaum qib poob.
Nws yog qhov sib txawv kiag li thaum nws los txog rau kev sib xyaw "mineral water" thiab hluavtaws lossis semi-synthetics. Ua qhov no yog txwv nruj heev thiab tsis pom zoo txawm tias thaum muaj xwm txheej ceev.
Cov tshuaj muaj pes tsawg leeg ntawm cov roj ntawm cov chav kawm sib txawv yog txawv kiag li. Tsis tas li ntawd, lawv muaj cov khoom siv ntxiv uas tsis sib haum xeeb thiab coagulation ntawm piston rings, clogging ntawm cov kav dej nrog ntau cov sediments tuaj yeem tshwm sim. Hauv ib lo lus, koj tuaj yeem rhuav tshem lub cav yooj yim heev.
Hauv kev xaus, ib qho tuaj yeem hais tau - txhawm rau kom tsis txhob muaj kev paub hauv koj tus kheej cov tawv nqaij dab tsi sib xyaw ntawm cov roj cav sib txawv ua rau, ib txwm yuav lawv rau kev siv yav tom ntej thiab nqa ib liter lossis tsib-liter canister nyob rau hauv lub cev xwb.
