1.9 TDI injini zofotokozera

Voliyumu yake yeniyeni ndi 1896 cm³. Kwa ichi anawonjezera yamphamvu ndi awiri a 79,5 mm, komanso masilindala 4 ndi mavavu 8. Stroke 95,5 mm, compression ratio 19,5. Injini ya TDI inalinso ndi makina ojambulira mpope a Bosch VP37. Njira iyi idagwiritsidwa ntchito mpaka 2004. Kumbali inayi, majekeseni omwe amagwiritsidwa ntchito popanga jakisoni wamafuta a hydraulic mu injini ya dizilo adagwiritsidwa ntchito mpaka 2011. 

Mayankho akhazikitsidwa mu injini za m'badwo woyamba

Chifukwa cha kugwiritsa ntchito jekeseni wa magawo awiri, chipangizocho chinapanga phokoso lochepa panthawi yogwira ntchito. Imakhala ndi jekeseni woyamba waung'ono wokonzekera silinda ya jakisoni wamafuta a silinda. Panthawi imodzimodziyo, kuyaka bwino, zomwe zinapangitsa kuti phokoso la injini likhale lochepa. 1.9 TDI-VP ilinso ndi turbocharger, intercooler ndi EGR valve, komanso ma heaters mu dongosolo lozizira. Izi zinapangitsa kuti kukhale kosavuta kuyambitsa galimotoyo potentha kwambiri.

1.9 TDI PD injini yokhala ndi mpope wa jakisoni

Kumayambiriro kwa chaka cha 1998, nkhawa ya ku Germany idakhazikitsa gawo lotsitsimula la 1.9 TDI lokhala ndi mpope watsopano wa jakisoni wokhala ndi nozzle yomwe idalowa m'malo mwa mphuno zachikhalidwe ndi mpope. Izi zinapangitsa kuti jekeseni ikhale yothamanga kwambiri komanso kuchepetsa kugwiritsa ntchito mafuta, komanso kupititsa patsogolo ntchito ya unit. Komabe, zotsatira zake zinali zokwera mtengo zokonza chifukwa cha ma flywheel oyandama omwe adayikidwa komanso makina osinthira a geometry. 

Kodi panali zovuta zilizonse pamainjini a 1.9 TDI?

Chikhalidwe chosauka pantchito chimatchulidwa ngati kufooka kwakukulu kwa magawo. Injiniyo idapanga phokoso komanso kugwedezeka kwambiri panthawi yogwira ntchito, zomwe zitha kukhala zokhumudwitsa makamaka mukamagwiritsa ntchito magalimoto otsika. Zinachitika pa liwiro lotsika. Pa liwiro la pafupifupi 100 Km / h, vuto mbisoweka. 

Mfundo zofunika kwambiri pakugwiritsa ntchito - kusintha lamba wanthawi ndi mafuta

Mukamagwiritsa ntchito injini ya 1.9 TDI, ndikofunikira kutsatira kusintha kwa lamba wanthawi. Izi ndichifukwa cha katundu wake wowonjezera. Camshaft imasuntha ma pistoni a jekeseni, omwe amapanga kuthamanga kwambiri, ndipo mphamvu yaikulu kwambiri yamakina imafunika kusuntha pisitoni yokha. Gawoli liyenera kusinthidwa pamene mtunda ukuwonjezeka kuchokera ku 60000 km kufika ku 120000 km. Ngati mugula galimoto mu msika yachiwiri, ndi bwino m'malo injini gawo mutangogula.

Kumbukirani kusintha mafuta anu nthawi zonse

Monga mitundu yambiri ya injini za Turbo, injini iyi "imakonda mafuta" choncho mlingo wa mafuta uyenera kufufuzidwa nthawi zonse, makamaka pambuyo pa ulendo wautali pamene dizilo ya 1.9 TDI yakhala ikulemedwa kwambiri.

Mitundu yosankhidwa ya VW - imasiyana bwanji?

Ma injini a 1.9 TDI okhala ndi mpope wozungulira wokhala ndi mphamvu kuchokera ku 75 mpaka 110 hp amaonedwa kuti ndi odalirika. Komanso, mtundu wotchuka kwambiri ndi 90 hp dizilo unit. Nthawi zambiri inali injini yokhala ndi ma turbines okhazikika a geometry, ndipo m'mitundu ina panalibenso magudumu oyandama oyandama, zomwe zidapangitsa kuti mtengo wake ukhale wotsika. Zawerengedwa kuti injini ya 1.9 TDI imatha kuyenda bwino, ndikukonza pafupipafupi, ngakhale kupitilira 500 km yokhala ndi kalembedwe koyendetsa. 

Gulu la Volkswagen limayang'anira ukadaulo wake mosamala

Kodi injini ya 1.9 TDI ndiyabwino? Chidule

Kodi gawoli ndiloyenera kuliganizira? Ubwino wa galimoto iyi ndi monga mtengo wotsika wokonza komanso kudalirika. Kukwera mtengo sikungangoyambitsa mitundu yoyandama ya ma flywheel, komanso kumasulira kwa magawo a dizilo. Komabe, kukonza nthawi zonse ndi kuthandizidwa ndi katswiri wamakina kungathandize kupewa mavuto okwera mtengo ndi sefa yanu ya dizilo kapena magawo ena a injini. Injini yosamalidwa bwino ya 1.9 TDI imatha kubweza chiyanjo ndikuyenda bwino komanso kuchita bwino.
