Encyclopedia ya injini: Mazda 2.0 Skyactiv-G (mafuta)

Ulendo wa Mazda ndi jekeseni wolunjika unayamba kale kwambiri kuposa kukhazikitsidwa kwa injini za Skyactiv, ndipo zinali zoyesayesa zopambana kwambiri. Chochitikacho chinasandulika injini yomwe imagwira yokha molimba mtima motsutsana ndi ochita nawo ma turbocharged mpaka lero.

Mazda petulo mwachindunji jekeseni anaonekera koyamba mu 2005 (2.3 DISI injini) mu Model 6. M'badwo wachiwiri Mazda 6 amagwiritsa 2.0 DISI unit (komanso Mazda 3), ndi injini Syactiv-G kuwonekera koyamba kugulu Mazda CX5 mu 2011. ndipo adapezanso ntchito yake mum'badwo wachitatu wa Mazda 6.

Chigawochi ndichotsogola mwaukadaulo, ndipo, ngakhale kusowa mphamvu, chili ndi mayankho monga chiŵerengero chapamwamba (14: 1), chomwe amakulolani kuti mugwire ntchito pa Atkinson-Miller kuzungulira, nthawi yosinthika ya valve kapena mapangidwe opepuka, ngakhale kuyendetsa nthawi kumayendetsedwa ndi unyolo. Palinso njira yoyambira yoyambira komanso i-ELOOP yomwe imabwezeretsa mphamvu kuti igwire ntchito mwachangu. Chinsinsi cha kupambana, mwachitsanzo, kukhalabe ndi mlingo woyenera wa umuna, ndikuwongolera kolondola kwa kuyatsa kwa kusakaniza. Galimoto imayamba kuchokera ku 120 mpaka 165 hp, choncho, amapereka mphamvu zabwino za kalasi iyi ya galimoto, ngakhale kuti imapatuka ku "miyezo ya turbo" ya mpikisano.

Mwachimake, injini singakhale yolakwika. Chokhalitsa, mafuta palibe vuto, ndipo Nthawi unyolo 200 zikwi. km amangofunika kufufuzidwa, osasinthidwa kawirikawiri. Mpweya wakuda umapezeka m'mainjini omwe ali ndi mafuta omwe amasinthidwa pafupipafupi. (max. Makilomita 15 aliwonse) kapena mutagwiritsa ntchito mafuta okhala ndi viscosity yolakwika (0W-20, 5W- amaloledwa). Ogwiritsa ntchito ankavutika makamaka ndi hardware.

Kuchucha kwa makina otulutsa mpweya ndi mita yowonongeka ndiyomwe imayambitsa mavuto oyambira injini kapena kugwedezeka. Nthawi zambiri, valavu ya blower imawonongeka, yomwe imawombera mafuta m'zipinda zoyaka, zomwe zimapangitsa kuyaka kwa detonation ndi kudzikundikira kwa mwaye.

Ubwino wogwiritsa ntchito injini ndikusowa kwa supercharging, zomwe zimachepetsa chiopsezo cha kulephera kwamtengo wapatali ndikupangitsa kapangidwe kake kukhala kosavuta. Ubwino wina waukulu ndi kuthekera kokhazikitsa dongosolo la HBO.

Mtundu waposachedwa wa injini ya Syactiv-G uli ndi makina oletsa ma cylinder awiri ndi makina osakanizidwa ofatsa, omwe amakulolani kuyendetsa ndi injini kwathunthu kwakanthawi kochepa.
