Kodi pali kusiyana kotani pakati pa injini ya dizilo ndi mafuta?

Ngakhale kuti magetsi atsopano monga gasi, magalimoto amagetsi osakanizidwa ndi E-85 akudziwika kwambiri, injini zambiri zoyatsira mkati zomwe zimagulitsidwa ku United States zimakhalabe ndi mafuta opanda utomoni kapena dizilo. Ngakhale kusiyana kwa mankhwala pakati pa mafuta awiriwa ndi ofunika kwambiri, momwe injini zimagwiritsira ntchito mafutawa kuti apange mphamvu ndizofanana kwambiri. Tiyeni tifotokoze kusiyana ndi kufanana kwamafuta ndi injini kuti muthe kusankha mwanzeru zomwe mungasankhe.

Kodi pali kusiyana kotani pakati pa petulo ndi dizilo?

Kwenikweni, mafuta ndi dizilo zimachokera ku petroleum, koma amagwiritsa ntchito njira zosiyanasiyana zoyeretsera. Mafuta amafuta opanda lead nthawi zambiri amakhala oyeretsedwa kwambiri kuposa dizilo. Amakhala ndi mamolekyu angapo a kaboni kuyambira kukula kwa C-1 mpaka C-13. Pa kuyaka, petulo amaphatikizana ndi mpweya kupanga nthunzi ndiyeno amayaka kuti apange mphamvu. Panthawiyi, mamolekyu akuluakulu a carbon (C-11 mpaka C-13) ndi ovuta kwambiri kuwotcha, chifukwa chake akuti 80% yokha ya mafuta amayaka mu chipinda choyaka moto poyesa koyamba.

Mafuta a dizilo samayengedwa pang'ono ndipo amasiyana kukula kuchokera ku C-1 mpaka C-25 mamolekyulu a kaboni. Chifukwa cha zovuta zamakina amafuta a dizilo, ma injini amafunikira kuponderezedwa, spark, ndi kutentha kwambiri kuti awotche mamolekyu akulu muchipinda choyaka. Mafuta a dizilo osawotchedwa amachotsedwa mu silinda ngati "utsi wakuda". Mwina munawonapo magalimoto akuluakulu ndi magalimoto ena a dizilo akutulutsa utsi wakuda kuchokera ku utsi wawo, koma ukadaulo wa dizilo wapita patsogolo mpaka pomwe ndi njira yosamalira chilengedwe komanso mpweya wochepa kwambiri.

Ma injini a petulo ndi dizilo amafanana kwambiri kuposa momwe amasiyana

Zowona, injini zamafuta ndi dizilo ndizofanana kwambiri kuposa momwe zimasiyana. Zonsezi ndi injini zoyatsira mkati zomwe zimatembenuza mafuta kukhala mphamvu kudzera mu kuyaka koyendetsedwa. Mafuta ndi mpweya zimasakanizidwa ndikupanikizidwa mumitundu yonse ya injini. Mafuta ayenera kuyatsa kuti apereke mphamvu yofunikira ndi injini. Onse amagwiritsa ntchito njira zowongolera utsi, kuphatikiza makina obwereza a EGR, kuyesa ndikuwotchanso zinthu zina m'chipinda choyaka. Onsewa amagwiritsanso ntchito jakisoni wamafuta ngati gwero lawo lalikulu la induction. Ma dizilo ambiri amagwiritsa ntchito ma turbocharger kuti akakamize mafuta ochulukirapo muchipinda choyaka kuti afulumizitse kuyaka kwake.

Kodi pali kusiyana kotani

Kusiyana pakati pa injini za dizilo ndi gasi ndi momwe zimayatsira mafuta. Mu injini ya petulo, mafuta ndi mpweya zimapanikizidwa palimodzi panthawi inayake pisitoni isanayambe kukankhidwira mmwamba kuti ifike pa spark plug. Spark plug imayatsa chisakanizocho, kutsitsa pisitoni ndikusamutsa mphamvu kudzera pamapatsira kumawilo.

Mu injini ya dizilo, kusakaniza kwa mpweya wa mpweya kumaponderezedwa kumayambiriro kwa kuyaka, komwe kumatulutsa kutentha kokwanira kuyaka ndi kuyatsa mafuta. Kuchita izi sikufuna ma spark plugs. Mawu akuti compression poyatsira amagwiritsidwa ntchito pa izi. Zofananazo zikachitika mu injini ya gasi, mudzamva phokoso, lomwe ndi chizindikiro cha kuwonongeka kwa injini. Ma injini a dizilo amavotera kuti azigwira ntchito mwanthawi zonse.

Mphamvu ndi torque ndi malo ena pomwe injini ziwiri zimasiyana ndipo zitha kukhala zofunika kwambiri pazolinga zanu. Ma injini a dizilo amapanga torque yambiri, yomwe imalola kuti galimotoyo iziyenda, makamaka ndi katundu wolemetsa, motero ndi yabwino kukoka ndikunyamula katundu wolemetsa. Ma injini a petulo amapanga mphamvu zambiri pamahatchi, zomwe zimapangitsa kuti injiniyo ikhale yothamanga kwambiri kuti ipititse patsogolo komanso kuthamanga kwambiri.

Childs, Mlengi amapereka galimoto yomweyo ndi petulo ndi dizilo injini. Ma injini osiyanasiyana adzachita mosiyanasiyana ndipo amasiyana mosiyanasiyana malinga ndi momwe akufunira, choncho ndi bwino kufananiza magawo ndikupita kukayesa galimoto posankha galimoto yogula.
