VR6 injini - zofunika kwambiri za unit kuchokera Volkswagen

Injini ya VR6 idapangidwa ndi Volkswagen. Kukhazikitsa koyamba kunayambitsidwa mu 1991. Monga chidwi, tinganene kuti VW nawonso kupanga VR5 galimoto, kamangidwe kake zochokera VR6 unit. Zambiri pakuyika VR6 zitha kupezeka m'nkhani yathu.

Zambiri zamagawo a Volkswagen

Pachiyambi, mukhoza "kumasulira" chidule VR6. Dzinali limachokera ku chidule chopangidwa ndi wopanga ku Germany. Chilembo "V" chimatanthawuza "V-motor", ndi chilembo "r" ku mawu akuti "Reihenmotor", omwe amamasuliridwa ngati injini yachindunji, pamzere. 

Mitundu ya VR6 idagwiritsa ntchito mutu wamba pamabanki awiri a silinda. Chigawochi chilinso ndi ma camshaft awiri. Iwo alipo onse mu injini Baibulo ndi mavavu awiri ndi anayi pa silinda. Chifukwa chake, kapangidwe ka unit kamakhala kosavuta pakukonza, zomwe zimachepetsa ndalama zogwirira ntchito. Injini ya VR6 ikupangabe. Ma Model okhala ndi injini iyi ndi awa:

• Volkswagen Golf MK3, MK4 ndi MK5 Passat B3, B4, B6, B7 ndi NMS, Atlas, Talagon, Vento, Jetta Mk3 ndi MK4, Sharan, Transporter, Bora, New Beetle RSi, Phateon, Touareg, EOS, CC;

• Malo: Alhambra ndi Leon;
• Porsche: Cayenne E1 ndi E2;
• Skoda: 3T yabwino kwambiri.

12 cylinder version

Mayunitsi opangidwa poyamba anali ndi ma valve awiri pa silinda, pa ma valve khumi ndi awiri. Anagwiritsanso ntchito camshaft imodzi polowetsa ndi kutulutsa mpweya mu chipika chilichonse. Pankhaniyi, palibe zida za rocker zomwe zidagwiritsidwanso ntchito.

Mtundu woyamba wa VR6 unali ndi kusamuka kwa mamilimita 90,3 pakusamuka kwathunthu kwa malita 2,8. Baibulo la ABV linapangidwanso, lomwe linagawidwa m'mayiko ena a ku Ulaya ndipo linali ndi malita a 2,9. Ndiyeneranso kutchula kuti chifukwa cha mizere iwiri ya pistoni ndi masilinda omwe ali ndi mutu wamba ndi mutu wa piston kapena pamwamba pake. ndi wopendekera.

Pa mtundu wa 12-silinda, V angle ya 15 ° idasankhidwa. Compress ratio inali 10: 1. Crankshaft inali pazinyalala zisanu ndi ziwiri zazikulu, ndipo makosi adachotsedwa wina ndi mzake ndi 22 °. Izi zidapangitsa kuti asinthe makonzedwe a masilindala, komanso kugwiritsa ntchito kusiyana kwa 120 ° pakati pa masilindala otsatizana. Bosch Motronic unit control system idagwiritsidwanso ntchito.

24 cylinder version

Mu 1999 mtundu wa valve 24 unayambitsidwa. Ili ndi camshaft imodzi yomwe imayang'anira mavavu olowetsa a mizere yonse iwiri. Mbali inayi, imayang'anira ma valve otulutsa mpweya wa mizere yonse iwiri. Izi zimachitika pogwiritsa ntchito ma valve. Chojambulachi ndi chofanana ndi camshaft yapawiri ya DOHC. Pakukhazikitsa uku, camshaft imodzi imayang'anira mavavu olowera ndipo ina imayang'anira ma valve otulutsa. 

W-motor - amalumikizana bwanji ndi mtundu wa VR?

Yankho lochititsa chidwi lomwe lidapangidwa ndi nkhawa ya Volkswagen linali kapangidwe ka mayunitsi okhala ndi dzina la W. Mapangidwewo adatengera kulumikizana kwa mayunitsi awiri a VR pa crankshaft imodzi - pakona ya 72 °. Woyamba mwa injini izi anali W12. Idapangidwa mu 2001. 

Wolowa m'malo, W16, adayikidwa mu Bugatti Veyron mu 2005. Chipangizochi chinapangidwa ndi ngodya ya 90° pakati pa mayunitsi awiri a VR8 ndipo chili ndi ma turbocharger anayi.

Kodi pali kusiyana kotani pakati pa injini ya V6 yachikhalidwe ndi injini ya VR6?

Kusiyana kwake ndikuti imagwiritsa ntchito ngodya yopapatiza ya 15 ° pakati pa mabanki awiri a silinda. Izi zimapangitsa injini ya VR6 kukhala yokulirapo kuposa V6. Pachifukwa ichi, gawo la VR ndilosavuta kulowa m'chipinda cha injini, chomwe poyamba chinapangidwa kuti chikhale ndi ma silinda anayi. Galimoto ya VR6 idapangidwa kuti izikhala yopingasa pamagalimoto akutsogolo.
