Njira zochepetsera nambala ya octane yamafuta

Pezani nambala ya octane

Poyamba, kuchuluka kwa mafuta amafuta kumatsimikiziridwa ngati sikudziwika pasadakhale. Kuti mudziwe, muyenera kuyerekeza mafuta ndi muyezo wa isooctane ndi heptane. Pali njira zingapo zodziwira:

1. Kafukufuku - gwiritsani ntchito injini ya pistoni imodzi, osatengera kukwera. Mwina chiwerengerocho chidzakhala chokwera kwambiri.
2. Njinga - kutsanzira kuyendetsa chifukwa cha injini ya pistoni imodzi. Mwina chiwerengerocho chidzachepetsedwa.
3. Chromatographic - imagwiritsidwanso ntchito, imakupatsani mwayi wozindikira zonyansa.
4. Mothandizidwa ndi zipangizo zapadera zonyamula katundu - njirayo imapereka deta yolondola kwambiri.

Tsopano, podziwa chiwerengerocho, mukhoza kuyamba kuchitsitsa. Ndipo zimenezi zingatheke m’njira zosiyanasiyana.

Njira zochepetsera octane

Pali zochepa zomwe mungachite, koma zonse ndizothandiza. Zosankha zimadalira zomwe mumakonda. Mutha kuchepetsa:

1. Kusungirako nthawi yayitali.
2. mankhwala a sulfure.
3. Mafuta amafuta okhala ndi ma octane otsika.

Njira yoyamba ndiyo ntchito yochepa kwambiri. Ndikokwanira kuyika mafuta m'chidebe ndikusunga momwe mungathere kuti muchepetse mtengo. Ngati kusungidwa molakwika, masana chiwerengerocho chidzasintha ndi 0,2-0,4.

Chachiwiri, chiwerengerocho chimatsitsidwa ndi mankhwala a sulfure, koma zinthu zowonongeka zimatha kuwonjezeredwa. Mwina iyi ndiye njira yovuta kwambiri, popeza zomwe zili pamwambazi ziyenera kupezekabe.

Kachitatu, mafuta otsika amawonjezedwa ku mafuta a octane, ndipo njira iyi ndi yofulumira komanso yabwino kwambiri kwa ambiri. Njirayi ndiyosavuta komanso yolondola kuphatikiza kuwongolera zotsatira chifukwa cha zida zonyamula zomwe zimapangidwira izi.

Malangizo

Kuti mutsitse bwino octane nambala ya petulo, muyenera:

1. Choyambirira: dziwani njira zowongolera ndi njira yowonjezerera, kupanga zoyambira (kuthamanga, kuchita bwino, kapena zonse ziwiri).
2. Gwiritsani ntchito zida zodzitetezera pokonzekera.
3. Gwiritsani ntchito njira yoyezera yolondola kwambiri, koma musaope kugwiritsa ntchito njira zingapo zoyezera, chifukwa zida zimathanso kulephera.

Kuchepetsa chiwerengero cha octane sikuchitika pansi pazigawo za mafakitale, chifukwa sizolondola pazachuma. Kutsika kodziyimira pawokha kwa chizindikiro kumatheka popanda vuto lililonse, ndipo njira yosavuta ndiyo kusiya mafuta kwakanthawi mu chidebe chotseguka.
