Kumvetsetsa Magiredi Abwino a Lubricant: Buku Lophunzitsira Kuteteza Injini

Mu dziko la kukonza magalimoto, ubwino wa mafuta umagwira ntchito yofunika kwambiri pakugwira ntchito bwino kwa injini komanso kukhala ndi moyo wautali. Ngakhale ogula ambiri akumvetsa kuti zinthu zimasiyana muubwino, ochepa amamvetsetsa kusiyana kwakukulu pakati pa mitundu ya mafuta ndi momwe amakhudzira thanzi la injini. Mosiyana ndi zinthu zambiri zomwe ogula amagwiritsa ntchito komwe ubwino wapamwamba ungapereke phindu lochepa, ndi mafuta, ubwino wake umagwirizana mwachindunji ndi chitetezo chokwanira komanso magwiridwe antchito.

Bungwe la American Petroleum Institute (API) lakhazikitsa njira yokhazikika yogawa mafuta a injini, ndipo mtundu uliwonse umayimira magwiridwe antchito ake. Njirayi ndi yofunika kwambiri makamaka kwa injini za dizilo, zomwe zimagwira ntchito movutikira kuposa mafuta ena a injini. Pamene ukadaulo wa injini ukupita patsogolo komanso malamulo okhudza chilengedwe akuchulukirachulukira, kumvetsetsa mitundu ya mafuta awa kumakhala kofunikira kwambiri kwa eni magalimoto ndi oyang'anira magalimoto.

Mafuta a CE-grade: Maziko a Mikhalidwe Yovuta
Mafuta odzola a CE amagwiritsidwa ntchito ngati maziko a injini za dizilo zomwe zimagwira ntchito pansi pa mikhalidwe yotsika, yolemera kwambiri komanso yothamanga kwambiri. Mafuta awa amapangidwa kuti ateteze injini mu zida zomangira, makina a zaulimi, ndi magalimoto akuluakulu omwe nthawi zambiri amakumana ndi mikhalidwe yosiyanasiyana yogwirira ntchito.

CD-Giredi ndi Kupitirira: Zofunikira pa Injini Yokhala ndi Turbocharged
Kwa injini za dizilo zokhala ndi turbocharged, zomwe zimapangitsa kutentha ndi kupanikizika kwakukulu, mafuta a CD-grade kapena apamwamba ndi ofunikira. Mafomula awa ali ndi zowonjezera zowonjezera ku:
- Pewani kupangika kwa turbocharger
- Pewani kutentha kwambiri mukatentha kwambiri
- Sungani mafuta oyenera kutentha kwambiri

CF-4: Wochita Masewero a Msewu Waukulu
Opangidwa makamaka kuti azigwiritsidwa ntchito mwachangu komanso molemera komanso nthawi yayitali yogwira ntchito, mafuta a CF-4 ndi abwino kwambiri mu:
- Kuletsa kusowa kwa mphete ya pistoni panthawi yogwira ntchito kwa nthawi yayitali
- Kulimbana ndi kukhuthala kwa mafuta komwe kungachitike panthawi yoyendetsa galimoto mosalekeza
- Kusunga kulimba kwa kukhuthala kwa madzi nthawi yayitali

CG-4: Katswiri wa Sulfure Wochepa
Mafuta a CG-4 akagwiritsidwa ntchito ndi mafuta okhala ndi sulfure yosakwana 0.05%, amapereka:
- Chitetezo chapamwamba kwambiri ku kuwonongeka kwa zinthu zowononga
- Kuwongolera bwino mphamvu zowongolera utsi
- Kugwirizana bwino ndi machitidwe owongolera mpweya woipa

CH-4: Chitetezo Chapamwamba cha Ma Injini Amakono
Ma injini a bimetallic piston okhala ndi mphamvu zowonjezera za jakisoni wamafuta komanso kutentha kwambiri kwa ntchito amafuna mafuta a CH-4, omwe amapereka:
- Kukhazikika kwapadera kwa kutentha
- Chitetezo chapamwamba cha kuvala kwa makina amafuta amphamvu kwambiri
- Kulimba kwa kukana kupanga kwa depositi

CI-4: Kukwaniritsa Zofunikira za Dongosolo Lotulutsa Utsi
Mainjini okhala ndi makina otulutsa mpweya (EGR) amafuna mafuta odzola a CI-4 omwe:
- Chepetsani zinthu zomwe zimayambitsa kuyaka kwa asidi
- Pewani kuipitsidwa kwa dongosolo la EGR
- Sungani ukhondo m'mikhalidwe yovuta kwambiri yogwirira ntchito

Katundu Wowonjezera wa Antioxidant
Mafuta odzola apamwamba amasonyeza bwino kwambiri kukana okosijeni, zomwe:
- Imawonjezera moyo wa mafuta mwa kupewa kuwonongeka kwa mamolekyulu
- Amachepetsa kupangika kwa matope
- Imasunga kukhazikika kwa kukhuthala pakapita nthawi

Ukhondo Wapamwamba ndi Kufalikira
Mafuta abwino kwambiri ndi awa:
- Kusunga zinthu zodetsa zomwe zayikidwa mu yankho
- Kuletsa kusonkhanitsa kwa ndalama pazinthu zofunika kwambiri
- Kusunga ukhondo wa injini pakati pa kusintha mafuta

Chitetezo Chovala Chapamwamba
Ma formula amakono amapereka chitetezo chabwino kwambiri pa:
- Zigawo za sitima ya valavu
- Mphete za pistoni ndi makoma a silinda
- Malo onyamulira katundu

Ubwino Wogwirira Ntchito
Mafuta apamwamba kwambiri amapereka:
- Kupopa madzi bwino pa kutentha kochepa kuti muyambe kuzizira
- Kuchepetsa kugwiritsa ntchito mafuta
- Kuchepetsa kukangana kwa mafuta

Pogwiritsa ntchito miyezo ya National III ndi National IV yotulutsa mpweya, ukadaulo wa injini ku China wapita patsogolo kwambiri. Kupita patsogolo kumeneku kwapangitsa kuti pakhale kusintha kofanana pakufunika kwa mafuta:

Kusintha kwa Magiredi a CD kupita ku CF/CH
Ma CD omwe kale anali ofala kwambiri tsopano atha ntchito pa injini zamakono, m'malo mwake ndi awa:
- Magiredi a CF pa ntchito zambiri zachikhalidwe
- Magiredi a CH a injini zoyendetsedwa ndi magetsi zapamwamba

Kuthana ndi Mavuto Omwe Amakhudza China
Popeza pali mikhalidwe yapadera yogwirira ntchito kuphatikizapo:
- Kudzaza magalimoto mopitirira muyeso
- Ubwino wa msewu wosinthasintha
- Kuchuluka kwa sulfure m'mafuta kosasinthasintha
- Maluso osiyanasiyana oyendetsa galimoto

Kugwiritsa ntchito mafuta abwino kwambiri sikuti kungolimbikitsidwa kokha komanso ndikofunikira kuti injini isawonongeke msanga komanso kuti isamakonze zinthu modula.
