Kupaka mafuta kwa injini. Muzimutsuka kapena ayi?

Kodi ndiyenera kugwiritsa ntchito mafuta onunkhira?

Tiyeni tilunjika pa mfundo. Nthawi zina zimakhala zomveka kugwiritsa ntchito mafuta otsuka. Koma nthawi zina izi sizofunika.

Tiyeni tiwunikenso zochitika zomwe kutenthetsa injini ndi mafuta apadera kudzakhala koyenera.

1. Kusintha mafuta a injini yanthawi zonse kukhala yosiyana kwambiri kutengera maziko kapena phukusi lazowonjezera zomwe zimagwiritsidwa ntchito. Pankhaniyi, palibe kufunikira kwachangu kuyeretsa crankcase ku zotsalira zamafuta akale. Komabe, kuwotcha motere sikungakhale kopambana. Mafuta agalimoto amafanana kwambiri malinga ndi mtundu woyambira komanso zowonjezera zomwe zimagwiritsidwa ntchito. Ndipo ngakhale zitasakanizidwa pang'ono, palibe choipa chomwe chidzachitike. Koma pali mafuta pamsika omwe ali ndi mawonekedwe apadera kapena kapangidwe kake. Mwachitsanzo, izi zimaphatikizapo mafuta odzola okhala ndi molybdenum kapena otengera esters. Apa, musanasinthe mafutawo, ndikofunikira kuti muwotche crankcase kuti muchotse zotsalira zamafuta akale momwe mungathere.
2. Kuchulukana kwakukulu pakati pa kukonza nthawi zonse. Mafuta pambuyo ndandanda utumiki moyo amayamba kutsekereza injini ndi kukhazikika mu grooves ndi recesses wa galimoto mu mawonekedwe a sludge madipoziti. Mafuta osungunula amagwiritsidwa ntchito kuchotsa ma depositi awa.
3. Kuzindikira pansi pa chivundikiro cha valve kapena mumsewu wa ma depositi akuluakulu amatope. Pankhaniyi, sizidzakhalanso zosafunika kudzaza mafuta otsekemera. Mafuta otsika, ngakhale atasinthidwa munthawi yake, amawononga pang'onopang'ono injiniyo.

Opanga mafuta otenthetsera injini amalimbikitsa kugwiritsa ntchito mankhwala awo nthawi iliyonse yokonza. Komabe, palibe chifukwa chenicheni cha izi. Uku ndikusuntha kwamalonda. Ngati mafuta asintha pa nthawi yake ndipo chivundikiro cha vavu chili choyera, sizingakhale zomveka kutsanulira madzi amphamvu kwambiri.

Zida zoyeretsera zamafuta otsuka zimagwira ntchito zofewa komanso zotetezeka kuposa zomwe zimatchedwa mphindi zisanu. Koma, komabe, mafuta otenthetsera amakhalabe ndi zotsatira zoyipa pazisindikizo zamafuta a ICE.

Zotsatira za kutulutsa mafuta pazisindikizo zamafuta ndizosamveka. Kumbali imodzi, ma alkalis ndi ma hydrocarbon owala omwe ali muzinthuzi amafewetsa zisindikizo zolimba ndipo zimatha kuchepetsa pang'ono kuchucha kwamadzi, ngati kulipo. Kumbali inayi, zida zomwezo zimatha kuchepetsa mphamvu ya chisindikizo chamafuta, chifukwa chake malo ake ogwirira ntchito adzawonongeka mwachangu, ndipo injini imayamba "kupumira" pakapita nthawi.

Chifukwa chake mafuta otsuka ayenera kugwiritsidwa ntchito ngati pakufunika. Palibe chifukwa chothirira nthawi zonse mu crankcase.

Kupaka mafuta "Lukoil"

Mwina mafuta otchuka kwambiri omwe amakambidwa m'misika yaku Russia ndi Lukoil. Zimawononga ndalama zogulitsa malonda pafupifupi ma ruble 500 pa 4-lita chitini. Amagulitsidwanso m'mitsuko ya malita 18 ndi mtundu wa mbiya (malita 200).

Pansi pa mankhwalawa ndi mchere. Zomwe zimapangidwira zimaphatikizapo zovuta zoyeretsera zowonjezera zochokera ku calcium. ZDDP zinc-phosphorous zigawo zikuluzikulu zimagwiritsidwa ntchito ngati zoteteza komanso zopanikizika kwambiri. Zomwe zili muzinthu za ZDDP mumafuta othamangitsidwa ndizochepa. Choncho, kwa ntchito zonse injini, iwo mwachionekere sikokwanira. Izi zikutanthauza kuti kuwotcha kumatha kuchitika popanda ntchito. Ngati mupatsa mota katundu, izi zitha kupangitsa kuti pakhale zigoli pamalo opondera kapena kuvala mwachangu.

Malinga ndi oyendetsa galimoto, Lukoil ndi kusungunula bwino kuti akhoza ndithu bwino kuyeretsa injini ya madipoziti osati akale kwambiri.

Kupaka mafuta "Rosneft"

Chinthu china chodziwika bwino pamsika waku Russia ndi Rosneft Express mafuta akutsuka. Amapezeka m'mitsuko ya 4, 20 ndi 216 malita. Mtengo wa chitini cha 4-lita ndi ma ruble 600.

Mafuta otsuka "Rosneft Express" adapangidwa pamaziko a mchere wotsuka kwambiri ndikuwonjezera zotsukira ndi zowonjezera zowonjezera. Amatsuka mwaye ndi zinyalala zosungidwa kuchokera ku ngalande zamafuta, nthawi ndi mbali za crankshaft ndi malo a ziwalo zathupi. Imasunga zonyansa zomwazika bwino mu voliyumu yake, zomwe zimakonda kutsika komanso osatulutsa mafuta posintha.

Flushing Rosneft Express imakhudza pang'onopang'ono zisindikizo, sikuwononga kapangidwe ka mphira. Pakuwotcha, kuyendetsa galimoto nthawi zonse sikuloledwa, chifukwa phukusi lowonjezera nthawi zambiri limakhala losauka kwa nyimbo zotere.

Kupaka mafuta "Gazpromneft"

Pamagalimoto amagalimoto, mutha kuwona mafuta a Gazpromneft Promo. Izi zimayikidwa ngati zotsukira pang'ono zamainjini amitundu yonse.

mafuta opangidwa mu zitini 3,5 ndi 20 malita, komanso Baibulo mbiya 205 malita. Mtengo wa chitini cha 3,5-lita pamsika ndi pafupifupi ma ruble 500.

Kinematic viscosity ya Promo flush ndi 9,9 cSt, yomwe, malinga ndi SAE J300 classification, imakhala yofanana ndi kutentha kwakukulu kwa kutentha kwa 30. Kuthira kwa madzi kumakhala pafupifupi -19 ° C. +232 ° C.

Chifukwa cha phukusi labwino la zotsukira ndi zowonjezera zowonjezera, kapangidwe kake kamakhala ndi zotsatira zochepa pamagulu a mphira ndi aluminiyamu a dongosolo lopaka mafuta. Zomwe zili zotsika za antiwear ndi zowonjezera zowonjezera zimakupatsani mwayi woteteza mota modalirika pakuyeretsa, ngati sichikuchulukirachulukira.

Kupaka mafuta MPA-2

Mafuta akutsuka MPA-2 si mtundu wosiyana, koma ndi dzina lodziwika bwino. Amayimira "Automotive Flushing Oil". Amapangidwa ndi mafakitale angapo oyenga mafuta: OilRight, Yarneft ndi makampani ang'onoang'ono opanda chizindikiro.

MPA-2 ndiye njira yotsika mtengo kwambiri yomwe ikupezeka pamsika. Mtengo wake nthawi zambiri umakhala wochepera ma ruble 500. Muli zida zosavuta zowonjezera zotsukira. Kumbali imodzi, zowonjezera zotere ndizoopsa kwambiri ku mbali za rabara za injini ndipo, ngati zikugwiritsidwa ntchito moyenera, sizingawononge injini. Kumbali ina, kuyeretsa bwino sikulinso kopambana.

Oyendetsa galimoto amanena kuti mafutawa amagwirizana ndi kuyeretsa kwa madipoziti akale kwambiri. Komabe, pamayesero ofananiza, imataya njira zina zodula. Ndizoyeneranso kudziwa kuti opanga osiyanasiyana, ngakhale ali ndi luso lapadera la kapangidwe kake, mafutawa amasiyana pang'ono ndi magwiridwe antchito.

Kupaka mafuta ZIC Flush

Nthawi zambiri, zopangidwa ndi kampani yaku Korea SK Energy zafalikira ku Russia zaka zingapo zapitazi. Ndipo ZIC Flush sizinali choncho.

Flushing ZIC Flush imapangidwa pamaziko opangira, pamaziko a SK Energy Yubase. Kukhuthala kotsika kwambiri: 4,7 cSt yokha pa 100 ° C. Amataya madzimadzi pokhapokha atadutsa chizindikiro cha -47 ° C pa thermometer. Kuwala mu crucible yotsekedwa ikafika kutentha kwa +212 ° C.

Mafutawa amalimbikitsidwa kuti azitsuka ma injini omwe amafunikira mafuta ocheperako. Mwachitsanzo, kwa injini zamagalimoto amakono aku Japan opangira mafuta 0W-20.

Ndizovuta kunena mosakayikira kuti ndi mafuta ati abwino kwambiri omwe amapezeka pamsika waku Russia. Zotsatira zambiri zomaliza zimatengera kuchuluka kwa kuipitsidwa kwa mota, kukhudzika kwa zinthu za mphira ndi aluminiyamu ku ma alkali aukali komanso ma hydrocarbon olowera kuwala, komanso momwe zimapangidwira zokha.

General malangizo monga osachepera kusankha kutenthetsa malinga ndi mamasukidwe akayendedwe chofunika galimoto. Ngati injini ikufunika mafuta a 10W-40 ngati mafuta okhazikika, ndiye kuti simuyenera kutsanulira mafuta otsika-makamaka. Pa nthawi yomweyo, mafuta okhuthala wandiweyani ndi osavomerezeka kwa Japanese mkulu-revving magalimoto opangidwa 0W-20 mafuta.

Mazda cx7 kwa 500. Mafuta a injini, akuthamanga.
