Chifukwa chiyani mafuta a 5W-30 ndi 5W-20 ali ofala kwambiri?

Kusintha mafuta ndi imodzi mwa ntchito zofunika kwambiri zosamalira galimoto. Magalimoto ambiri amagwiritsa ntchito mafuta a 5W-20 kapena 5W-30 chifukwa mafutawa amagwira bwino kwambiri kutentha kapena kutentha kwambiri.

Pankhani ya chisamaliro chagalimoto, palibe chofunikira kwambiri kuposa kusintha kwamafuta. Chifukwa chomwe 5W-30 ndi 5W-20 mafuta amagalimoto ndizofala chifukwa amagwira ntchito bwino ndi injini zosiyanasiyana. Nthawi zambiri, mafuta amtundu uwu ndi abwino kwambiri pa kutentha komwe kungatheke: 5W-20 ndi yabwino kwambiri kumadera ozizira, ndipo 5W-30 ndi yoyenera kutentha kwambiri. Nthawi zambiri, chilichonse mwa izi chiyenera kugwira ntchito bwino mu injini mosasamala kanthu za kutentha komwe kulipo.

Kusiyana pakati pa 5W-30 ndi 5W-20 injini mafuta

Kusiyanitsa kwakukulu pakati pa 5W-30 injini ya mafuta ndi 5W-20 ndikuti yotsirizira imakhala yochepa (kapena yowonjezereka). Akagwiritsidwa ntchito mu injini yamagalimoto, mafuta a 5W-20 amapangitsa kukangana kochepa chifukwa chakuchepa kwake, kutanthauza kuti kumapangitsa kuti pakhale kukoka pang'ono pazigawo za injini monga crankshaft, valavu, ndi pistoni. Izi zitha kupangitsa kuti mafuta achuluke pang'ono.

Kuchuluka kwamadzimadzi amafuta a 5W-20 kumathandizanso kuti pampu yamafuta isunthire mosavuta kuchoka pa poto yamafuta kupita ku injini yonse. Izi zimapangitsa 5W-20 kukhala yokonda nyengo yozizira kwambiri komwe ndikofunikira kukhala ndi mafuta ochepa omwe amatha kuyenda mosavuta poyambira. Kumene 5W-30 imalowa m'malo otentha kumene mafuta amadzimadzi amatha kusweka pa kutentha kwakukulu. Izi zikutanthawuza ku mphamvu ya mafuta a 5W-30 kuti asawonongeke mofulumira monga mafuta a 5W-20, kupereka chitetezo chokwanira cha ziwalo za injini.

Mafuta okhala ndi mamasukidwe omwewo ndi mafuta okhala ndi kukhuthala kosiyana

Amapangidwa kuti azigwira ntchito mosiyanasiyana kutentha, mafuta amitundu yosiyanasiyana ndi amodzi mwamafuta abwino kwambiri amagalimoto pamagalimoto. Mafuta a viscosity amodzi akale ankateteza ku nyengo yotentha ndi yozizira, malingana ndi kulemera kapena kuzizira kwambiri komwe ankagwiritsidwa ntchito. Izi nthawi zambiri zimatanthawuza kugwiritsa ntchito mafuta a 5W-30 m'dzinja ndi chisanu ndi 10W-30 m'chaka ndi chilimwe.

Kumbali inayi, mafuta amitundu yambiri amagwiritsa ntchito zowonjezera zowonjezera kuti awonjezere kukhuthala kwamafuta. Chodabwitsa n'chakuti, ma viscosity atukukawa amakula pamene mafuta akuwotcha, kupereka kukhuthala kwapamwamba pa kutentha kwakukulu. Mafuta akazizira, zowonjezera izi zimapanikiza, kupangitsa mafuta kukhala ochepa kwambiri, omwe ndi oyenera kugwiritsidwa ntchito pamatenthedwe otsika a injini.

Momwe Zowonjezera Mafuta Zimathandizira Kuyeretsa ndi Kuteteza Injini Yanu

Opanga mafuta amagwiritsa ntchito zowonjezera zamafuta zamagalimoto kuti apititse patsogolo magwiridwe antchito amafuta akafika popaka mafuta. Kuphatikiza apo, zina mwazowonjezera zowonjezera mumafuta zimaphatikizapo kuyeretsa magawo a injini kuchokera ku madipoziti, kuletsa dzimbiri kapena dzimbiri mkati mwa injini, ndikuletsa kuwonongeka kwa mafuta chifukwa cha okosijeni kapena kutentha kwambiri.

Ndi mafuta ati omwe eni magalimoto ayenera kugwiritsa ntchito?

Mukamayang'ana mafuta a injini omwe ali abwino kwambiri pagalimoto yanu, pali zinthu zina zomwe muyenera kukumbukira. Ngakhale kuti palibe kusiyana kwakukulu pakati pa chitetezo choperekedwa ndi mafuta a 5W-30 ndi 5W-20, pali kusiyana pang'ono pamagulu a viscosity ya aliyense. The thicker 5W-30 ayenera kukhala ndi mwayi pang'ono kutentha kutentha ntchito, pamene 5W-20 woonda ayenera kupereka chitetezo injini bwino pa kutentha otsika ndi kukhala ndi phindu linanso la kuwonjezeka pang'ono mafuta dzuwa.

Kusinthasintha kwamafuta amakono opangira mafuta kumatanthauza kuti mafuta a 5W-30 ndi 5W-20 amateteza injini yanu mofanana mosasamala nyengo kapena nyengo. Mobil 1 imapereka mafuta osiyanasiyana amitundu yosiyanasiyana kuti agwirizane ndi injini yanu. AvtoTachki imapereka mafuta apamwamba kwambiri kapena wamba a Mobil 1 ndikusintha kulikonse kwamafuta am'manja.
