Ubwino ndi kuipa kwa injini ya silinda itatu
2023-06-16
Ubwino:
Pali zabwino ziwiri zazikulu za injini ya silinda itatu. Choyamba, kugwiritsa ntchito mafuta kumakhala kotsika, ndipo ndi masilinda ochepa, kusamuka kumachepa mwachilengedwe, zomwe zimapangitsa kuchepa kwamafuta. Ubwino wachiwiri ndi kukula kwake kochepa komanso kulemera kwake. Kukula kwake kukachepetsedwa, kapangidwe ka chipinda cha injini komanso ngakhale chipinda chochezera chikhoza kukonzedwa bwino, ndikupangitsa kuti chikhale chosinthika kwambiri poyerekeza ndi injini ya silinda inayi.
Zoyipa:
1. Jitter
Chifukwa cha zolakwika zamapangidwe, ma injini atatu amasilinda amakhala osavuta kugwedezeka poyerekeza ndi injini zinayi zamasilinda, zomwe zimadziwika bwino. Izi ndizomwe zimapangitsa kuti anthu ambiri azizemba injini zitatu zamasilinda, monga Buick Excelle GT ndi BMW 1-Series, zomwe sizingapewe vuto lodziwika bwino la jitter.
2. Phokoso
Phokoso ndi limodzi mwamabvuto ambiri a injini atatu yamphamvu. Opanga amachepetsa phokoso mwa kuwonjezera zivundikiro zotsekereza mawu m’chipinda cha injini ndi kugwiritsira ntchito zipangizo zotsekereza mawu bwino m’chipinda cha okwera ndege, koma chimaonekerabe kunja kwa galimotoyo.
3. Mphamvu zosakwanira
Ngakhale ma injini atatu amasilinda tsopano akugwiritsa ntchito turbocharging komanso muukadaulo wa jekeseni wa silinda, pangakhale torque yosakwanira makina opangira magetsi asanayambe kukhudzidwa, zomwe zikutanthauza kuti pakhoza kukhala kufooka pang'ono poyendetsa pa liwiro lotsika. Kuphatikiza apo, mawonekedwe apamwamba a RPM amatha kubweretsa kusiyana kwina pakutonthoza komanso kusalala poyerekeza ndi injini ya silinda inayi.
Kusiyana pakati pa injini za 3-cylinder ndi 4-cylinder
Poyerekeza ndi okhwima 4-yamphamvu injini, pankhani injini 3 yamphamvu, mwina ambiri anachita choyamba ndi osauka galimoto zinachitikira, ndi kugwedeza ndi phokoso amaonedwa kobadwa nako "machimo oyambirira". Kunena zowona, injini zoyambira zitatu za silinda zinalidi ndi zovuta zotere, zomwe zakhala chifukwa cha anthu ambiri kukana ma injini atatu a silinda.
Koma kwenikweni, kuchepa kwa masilindala sikutanthauza kuti zinthu sizikuyenda bwino. Ukadaulo wamakono wa injini zamasilinda atatu wafika pamlingo wokhwima. Tengani injini yatsopano ya SAIC-GM ya Ecotec 1.3T/1.0T mwachitsanzo. Chifukwa cha kapangidwe koyenera ka kuyaka kwa silinda imodzi, ngakhale kusamutsidwako kumakhala kochepa, mphamvu zamagetsi ndi chuma chamafuta zimakula bwino.
