Toyota 2NR-FKE, 8NR-FTS madalaivala

Ma injini a petulo amtundu wa Toyota wa NR ndi amodzi mwa mibadwo yamakono yamayunitsi, yomwe ikupitilizabe kukula pamagalimoto apano amakampani. The Japanese anadabwa ndi manufacturability mayunitsi, kuchepetsa kuwononga mafuta ndi luso la "downsizing" bwino - kuchepetsa voliyumu kuti kuonjezera chilengedwe ubwenzi injini.

Zitsanzo 2NR-FKE ndi 8NR-FTS zimakhala zofanana kwambiri, ngakhale zitakhala zosiyana. Lero tikambirana padera za makhalidwe a mayunitsi, mavuto awo wamba ndi ubwino.

injini chitsanzo ili ndi turbocharger, amene amalola kukwaniritsa makokedwe zosaneneka ndi kukhalabe gwero mpaka 200 Km. Ndithudi, ndi buku laling’ono chotero, kungakhale kulakwa kuyembekezera gwero lalikulu. Iwo. deta ya injini ndi yosangalatsa kwambiri, chifukwa cha zofunikira za chilengedwe.

8NR-FTS imayikidwa pamitundu iyi: Toyota Auris, Toyota CH-R.

Ubwino wa mzerewu wa ma motors aku Japan

1. Phindu. Izi kwambiri zamakono ndi zamakono, amene anayamba kuikidwa mu 2015 pa Toyota magalimoto.
2. Kuyera kwachilengedwe. Miyezo yanthawi yosinthira kuchokera ku Euro 5 kupita ku Euro 6 ikuwoneka bwino m'magawo awa.
3. Sitima yapamtunda ya valve. Unyolo umayikidwa pa injini zonse ziwiri, zomwe zimakulolani kuti musaganizire za kukonza njira yogawa gasi ndikuchepetsa mtengo wa ntchito.
4. Kuchita. Ngakhale mabuku ang'onoang'ono, injini zakonzedwa mwangwiro ntchito m'madera yachibadwa m'nyumba pa magalimoto chikhalidwe.
5. Kudalirika. Njira zosavuta komanso zotsimikiziridwa zakhala zikugwiritsidwa ntchito pamagulu ena, palibe mavuto ang'onoang'ono pakugwira ntchito kwa galimoto.

Kodi pali zolakwika ndi zovuta pa mzere wa NR?

Ndi oimira awiriwa a mndandanda omwe adakhala odalirika, samawala ndi kuchuluka kwa matenda aubwana. Pakati pa minuses ndi gwero laling'ono kwambiri, kulephera kukonza zazikulu, komanso zida zosinthira zodula.

Pazigawo zina, muyenera kuyeretsa EGR ndikudya zambiri. Pa 8NR-FTS, turbine ingafunikenso kukonzedwa. Kale pambuyo 100 Km, motors kutaya chikhulupiriro chawo ndi kuyamba amafuna chidwi. Injini zimakhudzidwa kwambiri ndi mtundu wa mafuta ndi mafuta, kotero kuti madzi abwino okha omwe amalangizidwa ndi wopanga ayenera kutsanuliridwa.

Zomaliza za 2NR-FKE ndi 8NR-FTS motors

Izi ndi zida ziwiri zamakono zamakono zomwe zili ndi machitidwe osavuta komanso othandiza. VVT-i sayambitsanso mavuto aakulu, jekeseni imalimbana ndi mafuta aku Russia (koma popanda kutengeka). Unyolo wanthawi sizimayambitsa mavuto mpaka ma kilomita 120-150. Ngakhale zili zochepa, ma injiniwa ali ndi mtengo wotsika mtengo, kotero amatha kusinthidwa ndi mgwirizano pazaka zingapo.

Ngakhale ma injini ndi atsopano, palibe njira zopangira mgwirizano. Komabe, kuchuluka kwawo kumatanthawuza kuti mitundu yachiwiri yochokera ku Japan yomwe ili yabwino iyambika pamsika posachedwa. Simuyenera kuganiza za kukonza mayunitsi, izi zichepetsa zomwe azigwiritsa ntchito ndikusintha magawo ogwirira ntchito.
