Owopsa bwanji mafuta otsika mamasukidwe a injini

Posachedwapa, pakhala chizoloŵezi chodziwikiratu pamakampani opanga magalimoto pakugwiritsa ntchito mafuta otsika a viscosity motor mumainjini amakono. Kodi mafuta odzolawa ndi otani?

Ngati muyang'ana mosamala timabuku ta bizinesi pamafuta omwe adawonekera paziwonetsero zaka zisanu mpaka zisanu ndi ziwiri zapitazi, mudzawona kuti mafuta opulumutsa mphamvu opulumutsa mphamvu okhala ndi mamasukidwe a SAE 0W-20, ambiri, adadzikhazikitsa kale mu msika. Inde, poyamba ankachitidwa mosamala ndipo amagwiritsidwa ntchito pokhapokha ngati panalibe njira ina, ndiye kuti, pamene chiwerengero cha viscosity chinaperekedwa kwa galimoto inayake ndi zina zomwe mungasankhe sizinaloledwe.

Pang'onopang'ono, nkhawa za zinthu zotsika kachulukidwe kakang'ono zinatha, koma mavuto okhudzana ndi mafuta otsika kwambiri amawonekedwe amtunduwu adawululidwa. Ndikoyenera kutchula mbali zina zofunika za ntchito yawo mwatsatanetsatane. Mwachitsanzo, kafukufuku wa mafuta muyezo wa kalasi SAE 0W-20, amene kwa zaka zingapo, anavumbula mfundo zotsatirazi: pazifukwa zina, mafuta amenewa akhoza kuchititsa kuti avale ndipo ngakhale kulephera msanga kwa injini.

Zinapezeka kuti chimodzi mwa zifukwa za zolakwika zomwe zadziwika zinali zogwirizana ndi kachulukidwe kakang'ono ka filimu yamafuta, yomwe imakhala yocheperapo ngati kuipitsidwa kwa majekeseni, komanso chifukwa cha kuchepa kwa mamasukidwe akayendedwe komwe kumachitika chifukwa cha kulowa kwachilengedwe. gawo la mafuta mu mafuta panthawi ya injini.

Vuto lina ndi chodabwitsa cha LSPI (Low Speed ​​​​Pre ignition) chomwe chimayambitsa kuwonongeka kosayembekezereka kwa magawo a injini. Monga momwe kafukufuku wotsatira wasonyezera, chodabwitsa cha LSPI sichikugwirizana ndi mapangidwe a injini, komanso ndi mankhwala a phukusi lowonjezera mu mafuta a injini. Makamaka, pamainjini ang'onoang'ono okhala ndi ma turbocharging ndi makina ojambulira mafuta mwachindunji, nthawi zina kupanga phukusi lokhazikika lazowonjezera kungakhale kowopsa. Pofuna kuthetsa mavuto amenewa, aliyense wopanga mafuta a injini anayamba kufunafuna njira zawozawo zowathetsera.

Masiku ano, opanga mafuta onse otsogola ochokera ku USA, komanso mayiko aku Europe ndi Asia, kuphatikiza China, akuwoneka pakupanga mitundu yatsopano yamafuta otsika kwambiri. Mmodzi mwa oyamba kupereka chitukuko chake chapadera anali kampani yodziwika bwino yaku Germany Liqui Moly, yomwe idayambitsa mafuta oyambira amtundu wa Molygen NG 0W-20 pamsika. Malinga ndi akatswiri pankhani ya lubricant, mankhwalawa ndi chitsanzo cha njira yabwino yothetsera mavuto a injini zamakono.

Zokwanira kunena kuti Molygen NG 0W-20 ili ndi gulu lamakono la API SN Plus, lomwe linatengedwa ndi mabungwe amalonda apadziko lonse chaka chapitacho. Poyerekeza ndi mafotokozedwe am'mbuyomu a API SN, mawonekedwe atsopanowa akuwonjezera kukana kwa LSPI chodabwitsa, chomwe chimatheka pochotsa calcium ndi magnesium mu phukusi lowonjezera la detergent. Seti ya zowonjezera zokha zimasinthidwa kuti zigwirizane ndi kutentha kwamafuta otsika komwe kumafanana ndi magalimoto osakanizidwa.

Komabe, kusiyana ndi mafuta okhazikika omwe Molygen NG 0W-20 ali nawo sikumangokhalira "kutsuka phukusi" limodzi. Chifukwa chake, chifukwa cha mafuta oyambira a API 3+, Molygen NG 0W-20 ali ndi mawonekedwe apamwamba (poyerekeza ndi mafuta ofanana a viscosity iyi) 220 ° C, omwe amachepetsa kwambiri kugwiritsa ntchito mafuta m'mainjini ogwiritsidwa ntchito. Kuphatikiza apo, mafuta owonjezera aposachedwa amagwiritsidwa ntchito m'mafuta, omwe amachepetsa kukangana kwamkati mwamadzimadzi, zomwe zimawonjezera mphamvu zopulumutsa mphamvu.

Ndipo potsirizira pake, "icing pa keke" ndi wothandizira anti-wear additive zochokera ku organic metal compounds, kawiri kawiri kuposa "trinuclear molybdenum" yodziwika bwino. Kukhalapo kwake mumafuta sikumangoteteza injini kuti isawonongeke komanso kupulumutsa mafuta, komanso imapereka inshuwaransi yowonjezerapo ngati pali mavuto obwera chifukwa cha mafuta omwe amalowa mumafuta.
