1.9 SDi injini yochokera ku Volkswagen - chidziwitso chofunikira kwambiri pagawoli

Kuwonjezeka kwa chidule cha SDi Kuyamwa jekeseni wa dizilo - ziyenera kudziwidwa kuti mawuwa amagwiritsidwanso ntchito nthawi zina Kuyamwa dizilo mwachindunji jakisoni. Ili ndi dzina lazamalonda lomwe cholinga chake ndi kusiyanitsa injini zatsopano kuchokera kumitundu yocheperako ya SD − kuyamwa dizilo, yopangidwanso ndi Volkswagen. Injini ya 1.9 SDi ndi ya gulu ili. Werengani zambiri za izi m'nkhani yathu!

Zambiri zama injini a VW omwe amalakalaka mwachilengedwe

Poyambira, ndikofunikira kuphunzira zambiri zaukadaulo wa Volkswagen wa SDI. Izi ndizomwe zimagwiritsidwa ntchito popanga mayunitsi a dizilo omwe amapangidwa mwachilengedwe okhala ndi jakisoni wachindunji. 

Ma injini a SDi amagwiritsidwa ntchito makamaka pamagalimoto ndi ma vani. umisiri Kuyamwa jekeseni wa dizilo imagwiritsidwanso ntchito pamayendedwe oyendetsa zombo ndi magalimoto amakampani, omwe amapangidwa ndi mainjiniya a VW Marine ndi VW Industrial Motor.

Kodi ma drive a SDi amapezeka bwanji?

Ndikoyenera kudziwa kuti ma motors a mndandandawu akupezeka pamizere kapena mizere yowongoka yokhala ndi mayina a R4 ndi R5. Kugawa kumaphatikizapo injini zomwe zimasamutsidwa malita 1,7 mpaka 2,5 m'makina onse awiri. Mafotokozedwe enieni amatha kusiyanasiyana malinga ndi momwe injiniyo akufunira.

Injini ya SDi 1.9, monga mitundu ina, imayikidwa makamaka pamitundu yamagalimoto omwe kudalirika komanso kuyendetsa bwino ndikofunikira kwambiri. Izi ndichifukwa choti sagwiritsa ntchito njira yomanga ngati kukakamiza mpweya. Komabe, izi zimamasulira mphamvu ya injini yocheperako poyerekeza ndi injini zokhala ndi jakisoni wa turbocharging mwachindunji.

1.9 SDi injini - data yaukadaulo

Iyi ndi injini yamasilinda anayi yokhala ndi jakisoni wamafuta a SDi. Kusamuka kwenikweni kwa injini ndi 1 cm³, silinda yoboola 896 mm, sitiroko 79,5 mm. Chiŵerengero cha kuponderezana ndi 95,5:18,5.

Injini ya 1.9 SDi imayendetsedwa ndi Bosch EDC 15V+ control unit. Kulemera kwake ndi 198 kg. Njinga yamotoyo idapatsidwa zizindikiritso AGD, AGP, ASX, ASY, AYQ ndi AQM.

Mayankho apangidwe mu injini ya VW

Okonzawo anasankha chipika chachitsulo cha imvi, komanso zitsulo zazikulu zisanu ndi crankshaft yachitsulo. Mapangidwewo amaphatikizanso mutu wa aluminium alloy cylinder mutu ndi makonzedwe a ma valve awiri pa silinda, pa ma valve asanu ndi atatu. Chigawochi chilinso ndi otsatira chikho ndi camshaft imodzi yapamwamba (SOHC). 

Ndi chiyani chinanso chomwe chimapangitsa kuti mapangidwe awa awonekere?

Injini ya 1.9 SDi ili ndi manifold otulutsa (chitsulo choponyedwa) ndi manifold intake (aluminium alloy). Ponena za dongosolo lamafuta ndi zowongolera, Volkswagen idayika pampu ya jakisoni yokhala ndi makina amagetsi a Bosch VP37 ndi jakisoni wolunjika ndi majekeseni a mabowo asanu.

Chigawochi chimakhalanso ndi njira yoziziritsira yozungulira iwiri yokhala ndi zosinthira kutentha, zomwe zimayendetsedwa ndi thermostat. Kupanga kumaphatikizaponso:

• dongosolo utsi ndi madzi kuzirala;
• kutopa chitoliro;
• mafuta rediyeta;
• mafuta a hydraulic.

Ndi magalimoto ati omwe adayikidwa ndi injini ya 1.9 SDi?

Injiniyi idayikidwa pamagalimoto omwe ali ndi nkhawa ya Volkswagen. Ponena za mtundu wa makolo womwe, awa ndi mitundu ya VW Polo 6N / 6KV, Golf Mk3 ndi Mk4, Vento, Jetta King ndi Pioneer ndi Caddy Mk2. Kumbali ina, mu magalimoto a Skoda izi zidachitika ndi makope a Fabia. Injini ya 1.9 SDi idapatsanso mphamvu Seat Inca ndi Leon Mk1.

Kodi kuyendetsa kwa Volkswagen ndi kopambana?

Injini imadziwika ndi kuyaka kothandiza, zomwe zikutanthauza kuti gawo lapakati la ma silinda anayi limapereka ndalama zotsika mtengo - zokhala ndi mphamvu yayikulu ndipo zimatha kukwera kwambiri popanda mavuto akulu.

Komanso, ndi wokonda zachilengedwe. Izi zidatheka chifukwa cha makina amakono a jakisoni wamafuta omwe amaonetsetsa kuti mpweya umatulutsa mpweya wochepa. Komanso, chifukwa chogwiritsa ntchito camshaft imodzi yokha, mapangidwe agalimoto ndi osavuta, kukonza ndi kukonza kumakhala kosavuta.

Tekinoloje ya SDi imasangalala ndi ndemanga zabwino. Kuyamba kwake m'magalimoto kwakhala kopambana kwambiri, ndipo imodzi mwa injini zogwira ntchito bwino kwambiri ndi injini ya 1.9 SDi.
