Tese takanzwa kamwechete muhupenyu hwedu mumwe munhu achitaura zvakasimba kuti " mota inomhanya zvakanyanya pa98 octane peturu pane 95 octane peturu ” uye kuti kana uchishandisa peturu 98 inotonzwa “basa rakasiyana!”. Kazhinji, kunzwa uku hakuenderane nechokwadi. Kana isu tichitaura nezve utility kana mhuri mhando, kushandisa 98 kana 95 peturu "yakaenzana rita".
Mumotokari zhinji, kushandisa imwe kana imwe yacho hakuna mutsauko mukuita. Uyezve, nemutengo parita masendi gumi neshanu unodhura papeturu ye98, zvine musoro here kushandisa mafuta aya mumotokari ine mafuta anokurudzirwa ari makumi mapfumbamwe nemashanu epeturu? Kwete. Asi ngatibvise ngano yakatenderedza 98-octane peturu nenzira ine hwaro.
Mushure mezvose, chii chinonzi octanes?
Nhamba yeOctane kana octane inomiririra kugona kwekupokana kwemafuta anoshandiswa muinjini dzeOtto cycle (senge peturu, doro, CNG neLPG) kana ichienzaniswa neisoctane (mabviro: Wikipedia).Indekisi yakaenzana nekupikisa detonation yezana muzana musanganiswa we isoctane uye n-heptane. Nokudaro, 98-octane peturu ine detonation resistance yakaenzana nemusanganiswa we98% isoctane uye 2% n-heptane. Peturu ine octane ratings pamusoro pe100 zvinoreva kuti yakatopfuura, kuburikidza nezvinowedzerwa (MTBE, ETBE), iyo inomanikidza simba reisoctane - mienzaniso: aviation (avgas) nemakwikwi peturu).
Sei kune peturu ine octane dzakasiyana?
Nekuti hadzisi dzese injini dzakagadzirwa zvakafanana. Injini dzemotokari dzemitambo dzinoshandisa yakakwira compression ratios (kubva pa11:1 zvichienda mberi) - kureva kuti, inodzvanya musanganiswa wemhepo nepeturu kuita vhoriyamu diki - nekudaro kudiwa kwepeturu inokwanisa kumira kudzvanywa kweinjini kwenguva yakareba. injini isina kuputika. Saka, kune injini dzine mareshiyo epamusoro ekumanikidzana, mafuta ane nhamba yepamusoro yeoctane anogara achikurudzirwa.
Iyo yese yekupisa kutenderera kweinjini inoverengerwa uchifunga yakakurudzirwa octane level. Saka, kana ukaisa 95 peturu muinjini yakagadzirirwa kugamuchira 98 peturu, chinoitika ndechekuti peturu inoputika piston isati yasvika padanho repamusoro rekudzvanywa. Mhedzisiro: iwe ucharasikirwa nemari! Kana iri imwe nzira yakapoteredza (kuisa 98 peturu muinjini yakagadzirirwa 95 peturu) mhedzisiro chete ndeyokuti wakashandisa mari yakawanda kune mamwe marita emafuta, nekuti maererano nekubudirira kuwana hakuna.
Muchidimbu, ingano
Mota chete dzinotora mukana we 98-octane peturu ndidzo dzine mareshiyo akakwira - sekutaura kwataita, dzinowanzova mota dzemitambo. Ava ndivo chete vanonyatsotora mukana wehuni iyi uye vanoida kuti ishande kwayo uye vimbiso yekuvimbika. Sezvaungafungidzira, mota zhinji dzepeturu hadzidi mafuta aya. Kana iwe uchifunga kuti utility yako kana nhengo yemhuri ingango shandisa 98 peturu, unozoziva kuti ingori zano kubva kuuropi hwako.Asi kana motokari yako ichikurudzira kushandiswa kwepeturu ye98, iyi ndiyo yaunofanira kushandisa. Iwe unogona zvakare kuwedzera mafuta ne95 octane peturu, asi iwe uchaona kurasikirwa kwekuita uye kuwedzera kwemafuta ekushandisa izvo zvinogona kudzima mukana wawakawana pakutenga mafuta.
Ndinoziva sei kuti ndeipi peturu yekushandisa?
Ehe, haufanirwe kuziva chiyero chekumanikidza cheinjini yemotokari yako, ingotarisa bhuku revashandisi kana, neimwe nzira, tsvaga chinonamirwa (chiripo pachivharo chemafuta) chine chiratidzo chemafuta achashandiswa.
Mukupedzisa: kunze kwekunge injini yemotokari yako yakagadzirira kugamuchira 98 peturu haufe wakanzwa mutsauko kana ukashandisa peturu 95 chete. Musiyano uri mumutengo…
