Injini ya 1.9 JTD ndi ya banja la Multijet. Awa ndi mawu a gulu la injini za Fiat Chrysler Automobiles, zomwe zimaphatikizapo mayunitsi a turbodiesel ndi jakisoni wamafuta mwachindunji - Common Rail. Mtundu wa 1.9-lita udayikidwanso pamagalimoto a Alfa Romeo, Lancia, Cadillac, Opel, Saab ndi Suzuki.

Zambiri za injini ya 1.9 JTD

Kumayambiriro koyambirira, ndi koyenera kudzidziwitsa nokha ndi zidziwitso zoyambira zamagalimoto. Injini ya 1.9 JTD yokhala ndi ma silinda anayi idagwiritsidwa ntchito koyamba mu 156 Alfa Romeo 1997. Injini yomwe idayikidwapo inali ndi mphamvu ya 104 hp. ndipo inali galimoto yoyamba yonyamula anthu yokhala ndi injini ya dizilo yokhala ndi jekeseni wolunjika wamafuta.

Zaka zingapo pambuyo pake mitundu ina ya 1.9 JTD idayambitsidwa. Zakhazikitsidwa pa Fiat Punto kuyambira 1999. Injiniyo inali ndi turbocharger ya geometry yokhazikika, ndipo mphamvu ya unit inali 79 hp. Injini inagwiritsidwanso ntchito mu zitsanzo zina za wopanga Italy - Brava, Bravo ndi Marea.

Deta yaukadaulo ya gawo lamagetsi la Fiat

Mtundu wa injiniwu udagwiritsa ntchito chipika chachitsulo cholemera pafupifupi 125 kg ndi mutu wa silinda wa aluminiyamu wokhala ndi camshaft yokhala ndi ma valve ochita mwachindunji. Kusamuka kwenikweni kunali 1,919 cc, anabala 82 mm, sitiroko 90,4 mm, compression chiŵerengero 18,5.

Injini ya m'badwo wachiwiri inali ndi njanji yotsogola wamba ndipo idapezeka mumitundu isanu ndi iwiri yamagetsi. Mabaibulo onse, kupatulapo 100 hp unit, ali ndi turbocharger ya geometry yosinthika. Mtundu wa 8-valve umaphatikizapo 100, 120 ndi 130 hp, pomwe mtundu wa 16-valve umaphatikizapo 132, 136, 150 ndi 170 hp. Kulemera kwake kunali 125 kilogalamu.

Chizindikiro cha injini m'magalimoto amtundu wina ndi magalimoto omwe adayikidwapo

Injini ya 1.9 JTD ikadalembedwa mosiyana. Zinatengera zosankha zamalonda za opanga omwe adazigwiritsa ntchito. Opel adagwiritsa ntchito chidule cha CDTi, Saab adagwiritsa ntchito mawu akuti TiD ndi TTiD. Injini anaikidwa pa magalimoto monga:

• Alfa Romeo: 145,146 147, 156, 159, XNUMX, GT;

Mitundu iwiri ya turbo - ukadaulo wamapasa-turbo

Fiat adaganiza kuti kuyambira 2007 adzagwiritsa ntchito mitundu iwiri yatsopano ya turbocharged. Twin turbos adayamba kugwiritsidwa ntchito m'matembenuzidwe a 180 hp. ndi 190hp ndi makokedwe pazipita 400 Nm pa 2000 rpm. Yoyamba ya mayunitsi anaikidwa pa magalimoto a zopangidwa zosiyanasiyana, ndipo chachiwiri pa magalimoto nkhawa Fiat.

Kagwiritsidwe kagawo kagalimoto - muyenera kuyang'ana chiyani?

Magalimoto okhala ndi mphamvu iyi adachita bwino. Kupanga kwake kunali kwabwino kwambiri kotero kuti zitsanzo zambiri zili muukadaulo wabwino kwambiri ngakhale zaka zapita. 

Ngakhale ndemanga zabwino, 1.9 JTD injini ali ndi zovuta zingapo. Izi zikuphatikiza nkhani ndi dothi la dzuwa, manifold otopetsa, valavu ya EGR, kapena kutumiza pamanja. Dziwani zambiri za zolakwika zomwe zimachitika kwambiri. 

Kulephera kwa Flap 

M'mainjini a dizilo okhala ndi ma valve 4 pa silinda imodzi, ma swirl flaps nthawi zambiri amayikidwa - mu imodzi mwa madoko awiri olowera pa silinda iliyonse. Ma dampers amasiya kuyenda chifukwa cha kuipitsidwa kwa chitoliro cha turbodiesel cholowera. 

Izi zimachitika pakapita nthawi - chiwombankhanga chimasweka kapena kusweka. Zotsatira zake, chowongolera sichingapitirire kupitilira 2000 rpm, ndipo zikavuta kwambiri chotsekeracho chimatha kutsika ndikugwera mu silinda. Njira yothetsera vutoli ndikusintha madyedwe ambiri ndi atsopano.

Vuto ndi manifold otopetsa, EGR ndi alternator

Kuchuluka kwa madyedwe kungakhale kopunduka chifukwa cha kutentha kwambiri. Chifukwa cha izi, amasiya kulowa mutu wa silinda. Nthawi zambiri, izi zimawonetsedwa ndi mwaye wodziunjikira pansi pa okhometsa, komanso fungo lodziwika bwino la utsi wagalimoto.

Mavuto a EGR amayamba chifukwa cha valve yotseka. Kuyendetsa ndiye amapita mu mode mwadzidzidzi. Njira yothetsera vutoli ndikusintha chigawo chakale ndi chatsopano.

Kulephera kwa jenereta kumachitika nthawi ndi nthawi. Zikatere, imasiya kulipiritsa bwino. Chifukwa chofala kwambiri ndi diode mu voteji regulator. M'malo kufunikira.

Kusokonekera kwapamanja pamanja

Pa ntchito ya injini 1.9 JTD, kufala Buku zambiri amalephera. Ngakhale kuti si chinthu mwachindunji injini, ntchito yake chikugwirizana ndi galimoto unit. Nthawi zambiri, mayendedwe a giya lachisanu ndi chisanu ndi chimodzi amalephera. Chizindikiro chosonyeza kuti makinawo sakugwira ntchito bwino ndi phokoso komanso phokoso. M'masitepe otsatirawa, shaft yotumizira imatha kutayika ndipo magiya a 5 ndi 6 adzasiya kuyankha.

Kodi injini ya 1,9 JTD ingatchedwe yodalirika?

Zopinga izi zitha kukhala zokhumudwitsa, koma podziwa kuti zilipo, mutha kuziletsa. Dziwani kuti, kuwonjezera pa mavuto pamwamba pa ntchito injini 1.9 JTD, palibenso mavuto aakulu, zomwe zingayambitse, mwachitsanzo, kukonzanso kwakukulu kwa magetsi. Pachifukwa ichi, galimoto ya "Fiat" - popanda kuwonongeka kwakukulu, ikhoza kufotokozedwa ngati yodalirika komanso yokhazikika.
