Fuel Economy Rating Of Motor Oil

Txij li thaum cov teb chaws Europe txawv ntawm Tebchaws Meskas nyob rau hauv cov nqe lus ntawm lub cav tsim, lub tsheb tsav tsheb, thiab tsoomfwv cov cai ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, qhov sib txawv no kuj tseem cuam tshuam txog qhov sib txawv thiab qhov txawv ntawm European automakers 'kev saib xyuas rau cov roj cav. . Kev lag luam tsheb nyob sab Europe tau txais kev saib xyuas zoo rau kev txuag hluav taws xob, muab qhov tseem ceeb tshaj plaws rau kev lag luam tsheb roj tsheb thiab coj mus rau hauv tus account ob lub zog thiab kev ua haujlwm emission.
ACEA European lubricant classification standard, qhov tseeb 2007 version yog muab faib ua 3 series. Lawv yog:
A/B Series: Roj av thiab lub teeb-lub luag hauj lwm diesel cav roj
C series: haum rau catalyst hom cav roj
E Series: Heavy Duty Diesel Cav Roj
A / B series suav nrog: A1 / B1; A3 / B3; A3/B4; A5/B5.
C series suav nrog: C1; C2; C3; C4.
E series suav nrog: E2; E4; E6; E7.
Kev xaiv qib zoo
Lub cav lubricating roj zoo qib, tseem hu ua qib kev pabcuam, yog lub hauv paus tseem ceeb rau kev xaiv cov roj lubricating kom raug.
1. Diesel cav roj
Muaj ob lub hauv paus tseem ceeb rau kev xaiv cov qib zoo ntawm diesel cav lubricating roj. Ib qho yog raws li qhov sib npaug ntawm cov khoom siv thauj khoom thiab thermal load ntawm lub tsheb cav, sawv cev los ntawm kev txhawb nqa coefficient; lwm qhov yog raws li qhov hnyav ntawm lub cav ua haujlwm.
Rau kev kub ceev ib txwm aspirated thiab turbocharged plaub-stroke diesel xyaw ua tom qab 1990, diesel cav roj ntawm CF-4 lossis siab dua yuav tsum tau siv. Rau kev kub ceev plaub-stroke diesel xyaw uas tau tshwm sim tom qab xyoo 1998, txhawm rau hloov kho lub tshuab thev naus laus zis txhim kho thiab cov kev cai emission, yuav tsum siv cov roj cav diesel ntawm CH-4 lossis siab dua qib. CH-4 qib tuaj yeem hloov CF-4 thiab CD. High-speed plaub-stroke ib txwm aspirated thiab turbocharged, hnyav-lub luag hauj lwm diesel xyaw ua tom qab 2002 yuav tsum siv CI-4 los yog siab tshaj theem vim muaj cov pa roj recirculation li thiab cov kev cai ntawm cov qauv kev cai thiab tso pa roj tom qab- kev kho mob technology. diesel cav roj, uas tuaj yeem hloov CH-4, CF-4 thiab CD.
2. Cov roj av
Raws li qhov hnyav ntawm lub cav ua haujlwm, cov khoom siv ntxiv hauv cov tsheb thauj khoom thiab cov pa tawm, thiab lub xyoo ntau lawm, cov roj cav roj nrog cov qib kev ua tau zoo (qib zoo) yuav tsum raug xaiv. Feem ntau hais lus, cov roj qib siab tuaj yeem hloov cov roj qib qis, tab sis cov roj qib qis yuav tsum tsis txhob siv los hloov cov roj qib siab, txwv tsis pub nws yuav ua rau lub cav tsis ua haujlwm lossis txawm tias muaj kev puas tsuaj.
Rau ntau lub tsheb tshiab, raws li kev tsav tsheb ib txwm muaj, yog siv cov roj hluavtaws hluavtaws, cov roj cav tuaj yeem hloov pauv txhua txhua 10, 000 mais, thiab qee qhov tuaj yeem rub tau rau 20,000 mais. Cov kws kho tsheb pib ntseeg tias "kev tsav tsheb nruab nrab" yog hais txog kev tsav tsheb ntau zaus nrog ob peb nres thiab pib. Tab sis yog tias koj nquag tsav tsheb hauv nroog, muaj teeb pom kev nyob txhua qhov chaw, kev tsheb sib tsoo tshwm sim ntawm txhua qhov tig, thiab feem ntau ntawm qhov kev ncua deb ntawm ib qho kev mus ncig tsis tshaj kaum kilometers, hom kev tsav tsheb no tau muab cais ua "kev tsav tsheb tsis zoo".
