1.4 TDi VW injini - zonse zomwe muyenera kudziwa pamalo amodzi!

Injini ya 1.4 TDi idayikidwa mu magalimoto a Volkswagen, Audi, Skoda ndi Seat, i.e. onse opanga gulu la VW. Dizilo ndi jekeseni mwachindunji mafuta ankadziwika ndi chuma chabwino, koma panalinso mawu kugwirizana ndi zofooka zowawa, mwachitsanzo, kugwedera amphamvu kapena mavuto kukonza zotayidwa crankcase. Ngati mukufuna kudziwa zambiri za 1.4 TDi, tikukupemphani kuti muwerenge nkhani yonseyi.

Banja la injini ya TDi ya Volkswagen - zambiri zofunika

Chodziwika bwino ndikugwiritsa ntchito ukadaulo wa Turbocharged Direct Injection. Ma injini a dizilo a Turbocharged alinso ndi intercooler. Dziwani kuti Volkswagen amaika iwo osati pa magalimoto, komanso mabwato "Volkswagen Marine", komanso mayunitsi "Volkswagen Industrial Motor".

Injini yoyamba ya TDi inali injini yamasilinda asanu yomwe idayambitsidwa mu 1989 ndi Audi 100 TDi sedan. Chomeracho chidasinthidwa kukhala chamakono mu 1999. Okonzawo adawonjezerapo njira yojambulira mafuta a Common Rail. Kotero izo zinali ndi injini V8, amene anaikidwa pa Audi A8 3.3 TDi Quattro. Chosangalatsa ndichakuti injini ya TDi idagwiritsidwanso ntchito pamagalimoto othamanga mugulu la LMP1.

Kuphatikiza kwa njira ziwiri zamakono - jekeseni mwachindunji ndi turbocharging

Poyamba, makina ojambulira mafuta amapopera mafuta a dizilo mwachindunji m'zipinda zazikulu zoyaka moto. Chifukwa chake, njira yoyaka kwambiri yoyaka imachitika kuposa mu prechamber, otchedwa. jekeseni mwachindunji, yomwe imawonjezera torque ndikuchepetsa kutulutsa mpweya. 

Makina opangira utsi, nawonso, amapanikiza mpweya wolowa ndikuwonjezera mphamvu ndi torque mugawo lophatikizika, losamuka pang'ono. Kuphatikiza apo, ma injini a TDi ali ndi cholumikizira kuti achepetse kutentha ndikuwonjezera kuchuluka kwa mpweya woponderezedwa usanalowe mu silinda.

TDi ndi mawu otsatsa.

Amagwiritsidwa ntchito ndi mtundu wa Volkswagen Gulu, komanso Land Rover. Kuphatikiza pa kutchulidwa kwa TDi, Volkswagen imagwiritsanso ntchito dzina la SDi - Suction Diesel Injection yamitundu yopanda turbo yokhala ndi jakisoni wamafuta mwachindunji.

1.4 TDi injini - zambiri zofunika

Chigawo cha ma silinda atatu, chomwe chinapangidwa mu 2014 kuti chilowe m'malo mwa mtundu wa 1,2-lita kuchokera ku banja la EA189, chinagwiritsidwanso ntchito m'malo mwa 1,6 TDi ya four-cylinder. Chochititsa chidwi n’chakuti, kagawo kakang’ono kamene kanagwiritsa ntchito mbali zina za injini ya ma silinda anayi amene anawonjezedwa ku makina a silinda atatu.

Injini ya 1.4 TDi idapangidwa ngati ntchito yochepetsera. Chimodzi mwazinthuzo chinali kuchepetsa kulemera kwa crankcase ndi mbali za silinda, zinthuzi zidapangidwa ndi alloy ALSiCu3 yomwe imapezedwa ndi kuponyera mphamvu yokoka. Zotsatira zake, kulemera kwa injini yachepetsedwa ndi makilogalamu 11 poyerekeza ndi injini yapitayi ya 1,2l TDi ndi 27 kg yopepuka kuposa 1,6l TDi.

Ndi mitundu iti yamagalimoto yomwe injini ya 1.4 TDi idayikidwa?

Kuyendetsa kuchokera kubanja la EA288 kudayikidwa pamagalimoto monga:

• Audi: A1;
• Malo: Ibiza, Toledo;
• Skoda: Fabia III, Rapid;
• Volkswagen: Polo V.

Mayankho apangidwe kuchokera kwa mainjiniya a Volkswagen

Chigawo chamagetsicho chinali ndi shaft yoyendera yomwe imayendetsedwa ndi gearbox ya 1: 1 imodzi yothamanga mbali ina ya crankshaft. Sitiroko ya pisitoni yakwezedwanso mpaka 95,5 mm, kulola kusamutsidwa kwakukulu.

Mapangidwe ena amaphatikizapo ma valve anayi pa silinda imodzi, ma camshaft awiri a DOHC, komanso kugwiritsa ntchito mutu wa silinda womwewo womwe umapezeka mu injini za MDB za silinda zinayi. Zinanso zosankhidwa zinali kuziziritsa kwa madzi, intercooler, chosinthira chothandizira, DPF system, kubwereza kwa gasi wapawiri-circuit ndi EGR yotsika komanso yothamanga kwambiri, komanso DFS 1.20 jakisoni wopangidwa kuchokera kwa wopanga Delphi.

Zambiri zaukadaulo - mawonekedwe a injini 1.4 TDi

Injini ya 1.4 TDi imagwiritsa ntchito chipika cha aluminiyamu ya silinda ndi silinda. Ndi dizilo wamba njanji, mizere 4, masinthidwe atatu silinda ndi mavavu anayi pa silinda mu dongosolo DOHC. Ma cylinders mu njinga yamoto ndi awiri a 79,5 mm, ndi sitiroko pisitoni kufika 95,5 mm. Mphamvu yonse ya injini ndi 1422 cu. cm, ndipo compression chiŵerengero ndi 16,1:1.

Imapezeka mumitundu ya 75 HP, 90 HP. ndi 104hp Kuti mugwiritse ntchito bwino injini, mafuta a VW 507.00 ndi 5W-30 amafunika. Komanso, mphamvu ya thanki ya chinthu ichi ndi 3,8 malita. Iyenera kusinthidwa 20 XNUMX iliyonse. km.

Kuyendetsa galimoto - mavuto ndi chiyani?

Mukamagwiritsa ntchito injini ya 1.4 TDi, mavuto ndi mpope wa jakisoni amatha kuchitika. Zowonongeka zotsika mtengo zimayamba pakatha kuthamanga pafupifupi 200 km. km. Zosungira mphete ndizolakwika. The bushings kuvala mwachilungamo mwamsanga ndipo amalembedwa ngati chimodzi mwa zinthu zofooka pa galimoto msonkhano. Chifukwa cha iwo, kusewera kwa axial kwa crankshaft kumapangidwa.

Zosefera za DPF zilinso zotsekeka, zomwe zidabweretsa mavuto ambiri pamagalimoto okhala ndi mtunda wochepa. Magawo ena omwe amafunikira chidwi chapadera ndi awa: ma jakisoni a injini, ma flow meters komanso turbocharger. Ngakhale kuti unityo yakhala pamsika kwa nthawi yayitali, kukonzanso payekha kungayambitse ndalama zambiri. 

Kodi 1.4 TDi ndi chisankho chabwino?

Ngakhale zaka zapitazo, injini za 1.4 TDi zilipobe pamagalimoto ambiri omwe amagwiritsidwa ntchito. Izi zikutanthauza kuti khalidwe lawo ndi labwino. Pambuyo pofufuza mwatsatanetsatane za luso la unit, komanso galimoto yomwe ili, mukhoza kugula galimoto yabwino. Pankhaniyi, injini ya 1.4 TDi idzakhala chisankho chabwino, ndipo mudzatha kupewa ndalama zowonjezera mutangogula unit.
