Izindlela zokwehlisa inombolo ye-octane kaphethiloli

Thola inombolo ye-octane

Okokuqala, inani likaphethiloli liyanqunywa uma lingaziwa kusenesikhathi. Ukuze uthole ukuthi, kufanele uqhathanise uphethiloli ngezinga le-isooctane ne-heptane. Kunezindlela eziningana zokuthola:

1. Ucwaningo - sebenzisa injini yepiston eyodwa, hhayi ukulingisa ukugibela. Mhlawumbe isibalo sizoba phezulu kakhulu.
2. I-Motor - ukulingisa ukushayela ngenxa yenjini ye-piston eyodwa. Mhlawumbe lesi sibalo sizobukelwa phansi.
3. I-Chromatographic - isetshenziswa ngaphezu kwalokho, ikuvumela ukuthi ubone ukungcola.
4. Ngosizo lwemishini ekhethekile ephathekayo - indlela inikeza idatha enembile kakhulu.

Manje, ukwazi inombolo, ungaqala ukuyehlisa. Futhi lokhu kungenziwa ngezindlela ezihlukahlukene.

Izindlela zokunciphisa i-octane

Kunezinketho ezimbalwa, kodwa zonke ziyasebenza. Ukukhetha kuncike ekuthandeni komuntu siqu. Unganciphisa:

1. Ukugcina isikhathi eside.
2. ama-sulfure compounds.
3. Uphethiloli onesilinganiso se-octane esiphansi.

Inketho yokuqala iwumsebenzi omncane kakhulu. Kwanele ukubeka uphethiloli esitsheni bese ugcina okuningi ngangokunokwenzeka ukuze unciphise izinga. Uma igcinwe ngokungalungile, phakathi nosuku inombolo izoshintsha ngo-0,2-0,4.

Esimweni sesibili, inombolo yehliswa ngama-sulfure compounds, kodwa izinto ezi-resinous nazo zingangezwa. Mhlawumbe lena inketho enzima kakhulu, ngoba lokhu okungenhla kusadingeka kutholwe.

Esimweni sesithathu, uphethiloli onesilinganiso esiphansi wengezwa kuphethiloli we-octane ephezulu, futhi le ndlela ishesha kakhulu futhi ilungele iningi. Indlela ikhululekile futhi inembile ikakhulukazi ngokuhambisana nokulawula umphumela ngenxa yamadivayisi aphathekayo ahloselwe lokhu.

Amathiphu

Ukuze wehlise kahle inombolo ye-octane kaphethiloli, kufanele:

1. Okwandulelayo: nquma izindlela zokulawula kanye nendlela yokukhula, ukwenza izinto eziza kuqala (isivinini, ukusebenza kahle, noma kokubili).
2. Sebenzisa okokuvikela ngesikhathi kuqhubeka inqubo.
3. Sebenzisa indlela yokulinganisa enembe kakhulu, kodwa ungesabi ukusebenzisa izindlela zokulinganisa ezimbalwa, ngoba amadivaysi nawo angahluleka.

Ukwehlisa inombolo ye-octane akwenziwa ngaphansi kwezimo zezimboni, ngoba akufanelekile ngokwezomnotho. Ukwehla okuzimele kwenkomba kufinyelelwa ngaphandle kwezinkinga, futhi indlela elula ukushiya uphethiloli isikhathi esithile esitsheni esivulekile.
