Regular Gas vs. Premium Gasi: Ndeupi Musiyano uye Ndofanira Kuitira Hanya?

Kuita tsvakiridzo yekuwedzera inodiwa kuchengetedza madhora mashoma itsika yakajairika kune vazhinji vedu. Ukuwo, kana chikwama chedu chichiita sechakafuta kupfuura nguva dzose, tinowanzoshandisa zvakasununguka. Asi kana zvasvika kune pombi, zvine musoro here kuisa gasi nguva dzose mumotokari iyo inofanirwa kubhadharisa premium? Zvine musoro here kudira peturu yemhando yepamusoro mumotokari inongoda nguva dzose? Mhinduro dzinogona kukushamisa.

Injini inoshandisa sei peturu?

Kuti unzwisise kusiyana kwepeturu, zvinobatsira kuziva chaizvo kuti injini yako inoita sei kana inoshandisa gasi. Mafuta epeturu anobatsira mukupisa, izvo zvinoitika kana spark plug inounza diki magetsi anobatidza musanganiswa chaiwo wemhepo nemafuta mukamuri rinopisa. Simba rakagadzirwa kubva mukuita uku rinotyaira mapistoni mumasirinda anotyaira crankshaft, ichipa mota yako simba rainoda kufamba.

Kupisa inzira inononoka, uye huwandu hwespark hwakakwana kupisa musanganiswa wemhepo / mafuta pedyo ne spark plug, iyo inowedzera zvishoma nezvishoma kupisa zvimwe zvese. Injini inogadziriswa nekuda kwemhinduro iyi kuitira kuti ikwanise kutora simba rakawanda sezvinobvira, uye injini dzakawanda dzakagadzirirwa zvakasiyana kune zvinangwa zvakasiyana (somuenzaniso, motokari yemitambo inogadzirirwa simba, asi motokari yakasanganiswa inogadzirirwa hupfumi hwemafuta). uye munhu wese anoshanda zvakasiyana nekuda kweizvozvo.

Kugadzirisa injini nenzira iyi kwakakosha kune zvikonzero zvakawanda. Musanganiswa wemhepo-mafuta, iyo iyo murazvo wemoto isati yasvika, inoshanduka zvakanyanya mukumanikidza uye tembiricha isati yaitika. Kana mamiriro ari muhumburumbira aine kupisa kwakawandisa kana kudzvanywa kwemhepo / mafuta musanganiswa, inongobatidza yega, zvichikonzera kugogodza injini kana "detonation". Izvi zvinonziwo "kugogodza" uye zvinogadzira ruzha rwekurira sezvo kupisa kusingaite panguva yakakodzera iyo injini inoda kuita zvakanaka. Kugogodza kweinjini kunogona kusakosha zvachose kana kuva nemigumisiro yakakomba kana ikafuratirwa.

Chii chinonzi peturu uye inotengeswa sei?

Petroleum musanganiswa wehydrocarbon unosanganisira kabhoni nemvura sezvikamu zvawo zvikuru. Peturu inosanganiswa zvichienderana nemabikirwo akasarudzika, kusanganisira mazana maviri emahydrocarbon akasiyana kubva mupetroleum. Kuti uongorore kugogodza kupikisa kwepeturu, ma hydrocarboni maviri anoshandiswa: isooctane uye n-heptane, iyo inosanganiswa iyo inotarisa kushanduka kwemafuta maererano nekugona kupisa. Semuenzaniso, isooctane inopesana nekuputika kunongoerekana kwaitika, asi n-heptane inonyanya kunetseka nekuputika kunongoerekana kwaitika. Kana tawedzerwa pamwechete mune imwe formula, tinowana chiyero: Saka kana resipi iri 200% isooctane uye 85% iri n-heptane, tinoshandisa 15 (iyo muzana ye isooctane) kuona chiyero kana octane level.

Heino rondedzero inoratidza akajairwa octane mazinga kune akajairika peturu mabikirwo:

• 85-87 - Zvakajairika
• 88-90 - Superior
• 91 uye pamusoro - Premium

Nhamba dzacho dzinorevei?

Nhamba idzi dzinotarisa kuti peturu inobatidza nekukurumidza sei, zvichipihwa mamiriro einjini iyo ichashandiswa mairi. Saka, peturu yepamusoro hairevi kuti inopa simba rakawanda kune injini kupfuura peturu yenguva dzose; izvi zvinobvumira injini dzine hukasha (toti, turbocharged engines) kuwana simba rakawanda kubva pagallon yepeturu. Apa ndipo panouya kurudziro pamhando yemafuta emota.

Sezvo injini dzine simba (Porsche 911 Turbo) dzichigadzira kupisa kwakawanda uye kudzvinyirira kupfuura injini dzisina simba (Honda Civic), dzinoda imwe nhanho yeoctane kuti ishande zvakanaka. Maitiro einjini yekugogodza zvinoenderana neiyo compression ratio, iyo inokanganisa dhizaini yekamuri yekupisa pachayo. Chiyero chepamusoro chekumanikidza chinopa simba rakawanda panguva yekuwedzera sitiroko, iyo inobatsira zvakananga kune yakakwirira kudzvinyirira uye tembiricha muhumburumbira. Saka, kana iwe ukazadza injini isina kukwana octane mafuta, ine tsika yepamusoro yekugogodza.

Izvi zvinorevei pakugadzirisa?

Chirongwa cheMota uye Mutyairi chakaedza kuti marudzi akasiyana emafuta anokanganisa sei kuita kweinjini yemota dzakasiyana nemarori. Mukuedza kwezvikamu zviviri, vakaedza motokari dzinoverengeka (dzimwe dzichishandisa gasi renguva dzose uye dzimwe pamutengo mukuru) pagasi renguva dzose, vakabvisa matangi, vakaashandisa pagasi rekutanga kwemazuva mashoma, ndokuzoedzwa zvakare. Mukupedzisira, chero kuita kwekuita kubva pakuenda premium kwaive kure nekukosha uye zvechokwadi kusingakodzeri kuwedzera kwemutengo. Ukuwo, motokari zhinji (3 pa4) dzakaipa zvikuru kana dzisina kushandisa mafuta aitaurwa.

Injini dzemota dzakavakwa kuti dzichengetedze imwe yakagadziridzwa mwero wekuita, uye kurudziro yemafuta inogadzirwa nepfungwa iyoyo. Iko kutadza kwekukurumidza kweinjini kungasaitika, asi kunogona kuva nemhedzisiro yenguva refu iyo inogona kutungamirira kukugadzirisa kunodhura.

Wakazadza motokari nemafuta asiri iwo here? Dana makanika kuti anyatsoongororwa nekukurumidza.
