ndi chiyani, amasiyana bwanji ndi momwe angawasiyanitse?
Magalimoto onse amakono omwe amabwera kwa ife kuchokera ku Europe, USA, Japan ndi Korea ali ndi fyuluta ya particulate komanso chosinthira chothandizira. Zomwe zili, tanena kale patsamba lathu la Vodi.su. Tiyeni tingokumbukira mwachidule kuti kugwiritsa ntchito zinthu izi za mpweya wotulutsa mpweya kumakupatsani mwayi woyeretsa kwambiri mpweya wochokera ku muffler kuchokera kuzinthu zoyipa zamafuta ndi mwaye.
Mu malangizo a magalimoto amenewa, mukhoza kuwerenga kuti mafuta okha unleaded osachepera A-92 kapena A-95 ayenera kudzazidwa monga mafuta. Koma madalaivala ambiri sakwanitsa pankhaniyi. Kodi mafuta opanda lead angasiyanitsidwe bwanji ndi mafuta amtovu? Kodi pali kusiyana kotani pakati pawo? Tiyesetsa kupereka mayankho a mafunso amenewa.
Mafuta otsogolera
Kuonjezera chiwerengero cha octane mafuta kumayambiriro kwa mafakitale a magalimoto, mmodzi wa akatswiri a zamankhwala anaganiza kusakaniza mafuta ndi zina zapadera. Makamaka ndi tetraethyl lead. Monga momwe dzinalo likusonyezera, chigawochi chili ndi mtovu. Mankhwala opangidwa ndi mtovu ndi oopsa kwambiri, amawononga mpweya, ndipo anthu amavutika choyamba.
Ngati mumapuma mu nthunzi, ndiye kuti zotsatira zosasangalatsa zikuyembekezera munthu:
- mutu;
- kusamva bwino;
- ziwalo za kupuma dongosolo;
- imfa.
Kuphatikiza apo, kutsogolera kumakhazikika panthaka, masamba, komanso madzi otayira amalowa m'mitsinje ndi m'nyanja ndikuyenda motsatira unyolo wamadzi m'chilengedwe.
Mafuta okhala ndi tetraethyl lead ndi owopsa pamagalimoto onse. Choyamba, amaphulika pamlingo wochepetsetsa komanso kutentha kochepa. Chifukwa chake, ngati muwathira m'galimoto yakunja, mafunde ogwedezeka kuchokera pakuphulika adzawononga molimba mtima komanso mwadongosolo chipika cha silinda, mutu wa block, ndi makoma a pistoni.
Kachiwiri, kutsogolo kumakhazikika pamakoma a pores a chosinthira chothandizira. M'kupita kwa nthawi, chothandizira chidzangoyenera kutayidwa. Sitikukumbutsani kuchuluka kwa ndalama zosinthira. Palinso zotsatira zowononga pa sensa ya Lambda, yomwe imayendetsa mpweya wa okosijeni mu utsi. Mwachidule, galimoto yachilendo pamafuta oterowo sizima kwa nthawi yayitali. Chachitatu, chifukwa chake, ma jekeseni a jekeseni amatsekedwa mwamsanga, ndipo mawonekedwe ofiira ofiira amawoneka pamapulagi a spark.
Mafuta opanda lead
Kodi mafuta opanda lead ndi chiyani? Kwenikweni, kusiyana kokha ndi kusowa kwa kutsogolera kwambiri tetraethyl mu kapangidwe kake. Chifukwa cha kusowa kwa mankhwalawa, mafuta amtundu uwu sali oyenerera, koma makina a injini zamagalimoto amakono amangopangidwa kuti agwiritse ntchito. Kuchita bwino kwa kuyaka ndi kuphulika kumatheka pogwiritsa ntchito zowonjezera zochokera ku mowa ndi esters, zomwe zilibe mankhwala owopsa a lead ndi zitsulo zina.
Zowona, kuyaka kwamafuta opanda lead kumapangitsanso mpweya wowopsa, koma ambiri aiwo amakhala mu chosinthira chothandizira komanso fyuluta ya dizilo. Ndiko kuti, ndi wochezeka kwambiri ndi chilengedwe. Komanso, opanga mafuta akuwongolera nthawi zonse matekinoloje oyeretsera ku zonyansa zilizonse. Chifukwa chake, ngati muwonjezera mafuta pamagalasi otsimikiziridwa, komwe amatsimikizira mafuta apamwamba kwambiri, simuyenera kuda nkhawa kwambiri ndi injini ya kavalo wanu wachitsulo.
Mafuta amafuta opanda lead amadziwika bwino kwa onse oyendetsa galimoto:
- A-80 - kuyeretsa kotsika kwambiri, koyenera zida zapadera, magalimoto, magalimoto opangidwa ndi Soviet, mitundu ina ya njinga zamoto yokhala ndi injini zamtundu wa carburetor;
- A-92 - imatsanuliridwa mu akasinja a magalimoto ambiri apakhomo ndi aku China, oyenera magalimoto akunja omwe adatulutsidwa m'ma 1990;
- A-95 - mafuta ovomerezeka amagalimoto ambiri akunja a bajeti ndi gawo lalikulu;
- A-98 - Mafuta amtundu wapamwamba wamagalimoto okwera mtengo.
Pali, ndithudi, mitundu ina: A-72, A-76, Ai-91, Ai-93, Ai-96. Komanso Dziwani kuti pazipita zotheka octane nambala ya lead mafuta kufika A-110. A-100, A-98+, A-102 ndi pamwamba ndi mtundu wa mafuta othamanga, omwe amatsanuliridwa mu akasinja agalimoto zamagalimoto monga Ferrari, Lamborghini, Porsche, ndi zina zambiri.
Mwa njira, mafuta othamangira omwe amagwiritsidwa ntchito pamipikisano ya Formula 1 amatha kukhala otsogozedwa kapena osasunthika.
Kodi mafuta amafuta amatha kuwonedwa kapena kununkhiza?
Choyamba, ziyenera kunenedwa kuti ku Moscow ndi mizinda ikuluikulu ya Russian Federation mafuta otsogola ndi oletsedwa ndipo simudzawapeza pama network a malo odziwika bwino amafuta. Koma kumadera akumidzi, mutha kuthamangira muzosakaniza zabodza kapena zakupha zamitundu iwiri yamafuta.
Kodi kusiyanitsa iwo?
Malinga ndi miyezo yonse yomwe ilipo ku Russia ndi yakunja, mafuta abwinobwino ndi madzi omveka bwino, opanda mtundu. Onjezani utoto wa lalanje kapena wofiira kumafuta otsogola.. Komanso, zomwe zili kutsogolo zimatha kuzindikirika ndi fungo. Tingonena - mafuta amtundu wa lead amanunkha kwambiri komanso osasangalatsa.
