Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Sankhani mafuta a semi-synthetic kapena mafuta opangidwa kwathunthu, akadali vuto kwa eni ambiri omwe angasankhe. Anthu ena amati tiyenera kusankha semi-synthetic, chifukwa mtengo ndi wotsika, ndi bwino kusintha pafupipafupi. Ndipo anthu ena amati, kaphatikizidwe konse kuyenera kukhala kwabwino, chifukwa mtengo ndi katundu.

Pakuti galimoto yawo ayenera kusankha theka-kupanga okwera mtengo, kapena mokwanira kupanga mtengo-ogwira, Ndipotu, izi zimasiyana ndi galimoto galimoto, sangathe mwachisawawa anawonjezera, apo ayi osati kukhudza kuyendetsa galimoto, komanso akhoza kuwononga. zigawo zamagalimoto. Tiyeni tiwone kusiyana ndi mikhalidwe yomwe ikugwira ntchito.
Mafuta oyambira osiyanasiyana
Kusiyana kwakukulu pakati pa semi-synthetic ndi mafuta opangira kwathunthu ndi mafuta oyambira.
Pafupifupi 80% yamafuta a injini ndi mafuta oyambira. Mafuta oyambira nthawi zambiri amagawidwa m'magulu akuluakulu asanu, koma mafuta ambiri oyambira omwe amagwiritsidwa ntchito mumafuta amagalimoto ndi mafuta am'munsi ndi mafuta opangira.
Pakati pawo, mafuta oyambira omwe amapangidwa ndi njira yoyenga mafuta amatchedwa mafuta oyambira amchere, ndiye kuti, mafuta amtundu wachiwiri. Mafuta opaka omalizidwa opangidwa kuchokera ku mafuta amchere amchere amatha kukumana ndi mafuta odzipangira okha.
Koma pa kutentha kwambiri, kutentha kwambiri ndi malo ena, mafuta amchere sangathe kukwaniritsa zofunikira, kugwiritsa ntchito mafuta abwino opangira mafuta, omwe ndi mitundu itatu, mitundu inayi ya mafuta oyambira, komanso kugwiritsa ntchito mafuta opangira mafuta. galimoto ndi zonse kupanga mafuta.
Mafuta opangidwa athunthu ali ndi kukana kwamphamvu kwa okosijeni komanso kuyenda bwino kwa kutentha kochepa. Mafuta oyambira amafuta opangidwa bwino amapangidwa kuchokera kumitundu inayi yamafuta PAO + zowonjezera. Ngati ndi mafuta opangira otsika mtengo, amatha kupangidwa ndi polymerization yamitundu itatu yamafuta oyambira + haidrojeni.
Kawirikawiri, kusiyana kwamtengo pakati pa mafuta opangira mafuta ndi mafuta opangira theka ndi aakulu, chifukwa mafuta oyambira ndi osiyana ndi chilengedwe.
Zozungulira zosiyanasiyana
Chachiwiri, semi-synthetic mafuta ndi mafuta opangira mafuta chifukwa chamafuta osiyanasiyana, osati zowonjezera zomwezo, kotero kuti kuzunguliraku kumakhalanso kosiyana. Nthawi zonse, wokhazikika theka-kupanga mafuta 5000-8000km kapena zosakwana chaka m'malo. Izi ndi zabwino kwa ntchito ya injini, ngati si m'malo kwa nthawi yaitali kuchepetsa kwambiri kondomu zotsatira theka-synthetic mafuta; Kuzungulira kwathunthu kwamafuta opangira mafuta kumatha kukhala kozungulira 10,000 mpaka 13,000 km, komanso kutetezedwa bwino kwa injini.
Kupirira kutentha kosiyana
Chachitatu, mafuta a semi-synthetic komanso opangidwa mokwanira amagwira ntchito mosiyanasiyana kutentha ndikuteteza chipika cha injini ndi magawo osiyanasiyana.
Mafuta opangidwa mokwanira ndi oyenera ma injini a turbocharged ndi ma injini ochita bwino kwambiri okhala ndi kusamuka kwakukulu komanso kudzipangira okha chifukwa amatha kupirira kutentha kwambiri kuposa mafuta opangidwa ndi theka-synthetic. Chifukwa momwe injini ya turbocharged imagwirira ntchito ndi yoyipa, kukakamiza kwadzidzidzi komanso kuthamangitsa mwachangu sikungofunika kukhala ndi mafuta abwino, komanso kuyenera kukhala ndi mafuta abwino komanso filimu yoteteza. Apa ndipamene mafuta opangira amamenya mafuta a semi-synthetic motsimikiza.
Mtengo wake ndi wosiyana
Pomaliza, mafuta opangidwa ndi semi-synthetic komanso opangidwa kwathunthu amakhala ndi mitengo yosiyana. Kuchokera pafunso lapaintaneti lamitengo yamafuta a Mobil shopu yamafuta, mtengo wamafuta wa Mobil 1 Yinmei 5W-30 4L woyika pafupifupi 550 yuan, liwiro la semi-synthetic Ba 1000 5W-30 4L mtengo wamafuta ndi pafupifupi 250 yuan. Mwanjira ina, mafuta opangidwa ndi theka ndi pafupifupi theka la mtengo wamafuta onse opanga.
Mwachidule: Mafuta opangidwa ndi semi-synthetic amasiyana ndi mafuta opangidwa kwathunthu malinga ndi mafuta oyambira, kuzungulira kwa m'malo, kulolera kutentha, ndi mtengo. Kutengera ndi mawonekedwe awo, mafuta opangira zonse ndi oyenera kuyika injini zazikulu zosinthira ndi injini za turbocharged; Mafuta a semi-synthetic ndi oyenera kumainjini ang'onoang'ono osunthika.
