mafuta apamwamba. Ndikoyenera kuyendetsa?

Pamalo opangira mafuta, kuwonjezera pa mafuta osasunthika okhala ndi octane 95 ndi 98, dizilo yachikale ndi gasi, mutha kupezanso zomwe zimatchedwa mafuta abwino. Mtengo wawo ndi wokwera kwambiri kuposa mafuta wamba, koma kodi amatsimikizira kuti akuyenda bwino?

Kutsatsa konse kwamafuta amafuta amtengo wapatali kumatsikira ku mawu amodzi - mphamvu zambiri. Poyerekeza ndi magalimoto a Formula 1, mfufu wa moto kuchokera ku chitoliro chotulutsa mpweya, kuyamba ndi phokoso la matayala ... Tikudziwa zonsezi kuchokera ku malonda a TV. Zithunzi zonga zimenezi zingasonkhezere maganizo athu ndi kutilimbikitsa kudzaza mafuta okwera mtengo. Koma kodi ndi chisankho chabwinodi?

Verva (Orlen), V-Power (Shell), Ultimate (BP), milesPLUS (Statoil), Dynamic (LOTOS) ndi mafuta okonzedwanso omwe amaperekedwa kumalo opangira mafuta ku Poland. Mwachiwerengero, iwo ali pafupifupi PLN 20 kuposa anzawo wamba (ngati atakhala dizilo wapamwamba, izi ndizoposa PLN 30). Ambiri aiwo amachokera kwa ogulitsa aku Poland, kupatulapo Shell, yomwe imatumiza mafuta kuchokera kunja. Choncho, maziko ndi ofanana muzochitika zonse, ndipo mafuta amasiyana kwambiri ndi njira zomwe makampani amawonjezera. Zosakaniza zenizeni za zosakaniza sizidziwika.

Mafuta onse a petulo ndi dizilo yamtengo wapatali amakhala ndi sulfure wocheperako, mwa zina, zomwe zimawapangitsa kukhala obiriwira. Kuphatikiza apo, chifukwa chogwiritsa ntchito mafuta m'mafuta awa, zida zamkati za injini zimatha kuchepa. Chifukwa cha kugwiritsa ntchito zowonjezera, kuyaka kwamafuta abwino kumakhala koyera, komwe kumakhudza moyo wa injini.

Komabe, pankhani ya mphamvu, mayeso omwe amachitika mu labotale amangowonetsa kuchuluka kwake. Izi ndizosiyana kwenikweni - malinga ndi kuyerekezera, kuwonjezeka kwa mphamvu kuli pakati pa 1,6 - 4,5%. Ndipotu makwerero ang'onoang'ono a magetsi oterewa amatha kuchitika chifukwa cha kusintha kwa nyengo.

Andrzej Szczesniak, katswiri pa msika wamafuta, anati: “Mmene mafuta amtengo wapatali amakhudzira mmene injini imagwirira ntchito ndi chinsinsi chokoma cha opanga mafutawa. "Komabe, kawirikawiri, zimaganiziridwa kuti mafuta abwino amatha kuchita mosiyana kwambiri mu injini zosiyanasiyana," akuwonjezera.

Malingaliro ake, zaka za injini ndizofunikira kwambiri pankhaniyi.

- Zatsopano, zotsogola kwambiri zimatha kuchita bwino m'njira zambiri zikawotchedwa ndi mafuta apamwamba. Komano, pankhani ya injini zakale, mkhalidwe wawo ukhoza kuipiraipira. Mafuta amtengo wapatali amatha kutulutsa zonyansa zomwe zimamangidwa mu injini kwazaka zambiri, zomwe zimatha kutseka ndikuwononga jekeseni. Kumbukirani kuti pafupifupi zaka za galimoto ya ku Poland ndi zaka 15, ndipo m'galimoto ya m'badwo uno ndiyenera kusamala podzaza mafuta apamwamba. Komabe, tikhoza kuthira mafuta m’magalimoto atsopano,” akutero Szczesniak.

Mawu ake akutsimikiziridwa ndi Michael Evans, injiniya waku Britain yemwe wakhala akukonzekera mafuta a Shell kwa magalimoto a Ferrari Formula 1 kwa zaka zambiri.

"Ndimadziwa bwino kwambiri kapangidwe ka Shell V-Power ndipo ndikukutsimikizirani kuti mafutawa ndi abwino kwa injini zatsopano. Osati kokha, iwo ndi abwino kuposa mafuta okhazikika chifukwa ali ndi zigawo zomwe zimateteza zitsulo za injini. Chochititsa chidwi n'chakuti, mafuta amtengo wapatali amagwiritsa ntchito zinthu zomwezo monga magalimoto a Formula 1, koma mosiyanasiyana, akutero Evans.

"Ndimagwiritsa ntchito mafuta amtengo wapatali okha m'galimoto yanga," akutsimikizira.

Mafuta owonjezera

Mafuta okonzedwa bwino sali okwanira. Pafupifupi pa malo aliwonse opangira mafuta, zowerengera zimakhala zodzaza ndi mitundu yonse ya zowongolera. Akatswiri samalangiza motsutsa iwo, koma nthawi yomweyo amalangiza modekha.

M'magalimoto akale a dizilo, pakhoza kukhala vuto la kusowa kwa sulfure, komwe kumakhala ngati mafuta m'mayunitsi otere. Pamene magalimoto okhala ndi injini zamakono za dizilo zochokera ku njira wamba njanji mwachindunji jekeseni anayamba kulowa kupanga, sulphated dizilo mafuta anali ndi zotsatira zoipa pa ntchito ya mayunitsi. Chifukwa chake, zoyenga zidakakamizika kuchepetsa kuchuluka kwa sulfure mumafuta a dizilo.

Izi zidakulitsa moyo wa mayunitsi atsopano, koma panali vuto ndi ma dizilo akale. Akatswiri amalangiza kuwonjezera mankhwala kwa Aquarium nthawi ndi nthawi kudzaza mipata imeneyi.

Nkhani yosiyana ndi nyengo yachisanu, yomwe ingakhudze eni ake a injini za dizilo. Pamalo otentha (pafupifupi madigiri 20 Celsius), parafini imatha kugwa mumafuta a dizilo, omwe amatsekereza dongosolo lamafuta (makamaka fyuluta). Mankhwala otchedwa depressants amabwera kudzapulumutsa, kuchepetsa kulolerana ndi madigiri Celsius ochepa.
