Silinda ya injini ya petulo imagawidwa kukhala chitsulo choponyedwa ndi aluminiyamu. Fananizani ubwino ndi kuipa kwa silinda ya aluminiyamu ndi silinda yachitsulo: 1) Kulemera

Mphamvu yokoka ya aluminiyamu ndi yaying'ono kuposa yachitsulo chonyezimira, ndipo chipika cha aluminiyamu cha silinda ndi chopepuka kwambiri chifukwa chokwaniritsa zofunikira zamphamvu. Injini ndi yopepuka, yomwe imakhala ndi zotsatira zabwino pakugawa kulemera kwa galimoto, ndipo kulemera kwa galimoto kumakhala kopepuka. Chifukwa chake, pakadali pano, masilindala a aluminiyamu amalamulira.

2) Voliyumu

Pachifukwa chomwechi, mphamvu yokoka ya aluminiyamu ndi yaying'ono, ndipo mphamvu yapangidwe ya aluminiyumu pa voliyumu imodzi ndi yocheperapo kuposa yachitsulo choponyedwa, kotero ma silinda a aluminiyumu nthawi zambiri amakhala aakulu. EA113/EA888's silinda block ili ndi mtunda wapakati-to-cylinder mtunda wa 88mm, pomwe mtundu womwe ulipo uli ndi mainchesi a silinda mpaka 82.5mm. Kupatula ngalande yamadzi ozizira, khoma la silinda ndilochepa kwambiri. Mwanjira iyi, injini yonseyo ndi yaying'ono komanso yaying'ono. Masilinda a aluminiyamu ndi ovuta kwambiri kukwaniritsa izi. Panthawi imeneyi, chipika chachitsulo chachitsulo chimakhala chachikulu. [Zowonjezera: Kulimba kwachitsulo cha ductile cast iron kumatha kupitilira 1000MPa, pomwe mphamvu yamanjenje ya aluminiyamu 7075 aloy ndi 524MPa, kachulukidwe kachitsulo ndi 7.85, ndi kachulukidwe ka aluminiyamu ndi 2.7. Chifukwa chake, kuti mupeze mphamvu zomwezo, voliyumu ya aloyi ya aluminiyamu iyenera kuonjezedwa pafupifupi imodzi. Nthawi, koma kulemera kwake kumakhala pafupifupi 40% kupepuka]

3) Kukana kwa dzimbiri ndi mphamvu

Aluminiyamu ndiyosavuta kuchitapo kanthu ndi madzi opangidwa pakuyaka, ndipo kukana kwake kwa dzimbiri sikuli bwino ngati midadada yazitsulo zotayidwa, makamaka zamainjini apamwamba kwambiri omwe ali ndi kutentha kwambiri komanso kupanikizika. Ndipo mfundo yapitayi ponena za voliyumu, Komano, pamene injini yanu ya injini imakhala yochepa kwambiri, zimakhala zovuta kukwaniritsa mphamvu ya chipika chachitsulo chachitsulo chokhala ndi zitsulo zotayidwa. Chifukwa chake, ma injini ambiri okwera kwambiri amagwiritsa ntchito zitsulo zotayira, monga (m'badwo wa 9 usanachitike) EVO's 286hp 2.0L I4 (4G63), yomwe nthawi zonse imakhala midadada yachitsulo. Malire ake osinthika apamwamba amadziwikanso bwino. Ngati silinda ya aluminiyamu ikugwiritsidwa ntchito, sizingakhale zophweka. Panthawi imeneyi, chipika chachitsulo chachitsulo chimakhala chachikulu.

4) Mtengo

Mtengo wake ndi wachilengedwe kuti silinda ya aluminiyamu ndi yokwera mtengo, ndipo palibe chofotokozera. Panthawi imeneyi, chipika chachitsulo chachitsulo chimakhala chachikulu.

5) Kukana kuphulika ndi kutaya kutentha

Aluminiyamu imapangitsa kutentha mwachangu, kotero imakhala ndi ntchito yabwino yozizirira, yomwe ingathandize injini kuchepetsa kuthekera kwa kuyaka kwachilendo. Pakukakamiza komweko, ma injini a aluminiyamu yamphamvu amatha kugwiritsa ntchito mafuta otsika kwambiri kuposa injini za silinda zachitsulo. Pakadali pano, chipika cha aluminiyamu cha silinda ndichopambana.

6) Coefficient ya friction

Pofuna kuchepetsa inertia ya ziwalo zobwerezabwereza ndikuwonjezera kuthamanga kwa kasinthasintha ndi liwiro la kuyankha, ma pistoni ambiri amagwiritsa ntchito alloy aluminium ngati zinthu. Ngati khoma la silinda limapangidwanso ndi aluminiyumu, kugundana kwapakati pa aluminiyamu ndi aluminiyamu kumakhala kwakukulu, komwe kumakhudza kwambiri magwiridwe antchito a injini. Chitsulo chachitsulo chilibe vuto lotero. Panthawi imeneyi, zitsulo zotayira zachitsulo zimalamulira. [Zowonjezera: injini zina zotchedwa "aluminiyamu zonse" zimagwiritsanso ntchito zomangira zachitsulo] Pomaliza:

Ubwino wa aluminiyumu: kulemera kopepuka, kutentha kwabwino;
Ubwino wachitsulo: wotsika mtengo komanso wokhazikika.
