Kodi octane nambala ya petulo ndi chiyani

Octane ndi kuthekera kwa mafuta kupirira kupsinjika. Magalimoto ochita bwino kwambiri amafunikira mafuta ochulukirapo a octane kuti apititse patsogolo magwiridwe antchito.

Madalaivala ambiri anafika pamalo okwerera mafuta n’kukathira mafuta amtundu winawake. Nthawi zambiri, malo opangira mafuta amapereka mitundu itatu yamafuta okhala ndi ma octane osiyanasiyana.

Komabe, si tonsefe amene timadziwa kuti nambala ya octane ndi chiyani, ndipo timangodziwa kuti wina ali ndi 87, wina ali ndi 89, ndipo mtengo wapatali uli ndi 91 octane.

Kodi nambala ya octane mu petulo ndi chiyani?

Yankho lalifupi ndiloti octane ndi muyeso wa kuchuluka kwa kupanikizana komwe mafuta amatha kupirira asanayaka. M'mawu a anthu wamba, kuchuluka kwa octane kumakhala kocheperako, m'pamenenso mafuta amatha kuyatsa ndi kuthamanga kwambiri ndikuwononga injini yanu. 

Ichi ndichifukwa chake magalimoto othamanga kwambiri okhala ndi ma injini apamwamba amafunikira mafuta okwera kwambiri a octane (premium). Kwenikweni, mafuta okwera kwambiri a octane amagwirizana ndi injini zopondereza zapamwamba, zomwe zimatha kuwongolera bwino komanso magwiridwe antchito, zomwe zitha kutsitsa utsi powotcha mafuta kwathunthu.

M'madera ambiri a US, mafuta amtundu wamba amakhala ndi octane 87, sing'anga ndi 89, ndipo mtengo wake ndi 91-93. Ziwerengerozi zimatsimikiziridwa ndi kuyesa injini, zomwe zimabweretsa miyeso iwiri: kufufuza nambala ya octane (RON) ndi injini. Nambala ya Octane (MCH). ).

Eni magalimoto ambiri sangadziwe momwe injini yoyatsira mafuta imagwirira ntchito kapena chifukwa chake octane ndiyofunikira. Ena angaganize kuti kugulitsa mafuta okhazikika ku petulo yamtengo wapatali, chifukwa cha mtengo wake wotsika komanso wapamwamba, ndi njira yogulitsira "mafuta wamba" ku "mafuta apamwamba". M'malo mwake, mitundu yosiyanasiyana imatanthawuza mitundu ya injini zamagalimoto zomwe zimafunikira magawo osiyanasiyana a octane mu petulo.

Kodi Octane imagwira ntchito bwanji mu injini?

Kutengera ndi kapangidwe ka injini yagalimoto, octane amagwira ntchito yofunika kwambiri pakugwira ntchito kwa injini ndikuwunika kuthekera kokana kuyaka komwe kumangochitika mwadzidzidzi, komwe kumadziwika kuti detonation.

Injini yoyatsira mafuta yamkati imakanikiza chisakanizo cha mpweya ndi mafuta m'masilinda ake, potero kumawonjezera kutentha ndi kukakamizidwa kwa osakaniza. Kusakaniza kwa mpweya / mafuta kumayatsidwa ndi spark panthawi ya kupanikizana, ndipo kuyaka kumeneku kumatulutsa mphamvu ya kutentha yomwe pamapeto pake imayendetsa galimotoyo. Kugogoda kumachitika pa kutentha kokwanira (chifukwa cha kukanikiza) mu masilinda a injini. M'kupita kwa nthawi, kugogoda kumachepetsa mafuta a galimoto, kumawononga mphamvu ya injini, komanso kuwononga injini.
