<\/a>TEST VW Phaeton 6.0 W12 – Lidumil (03\/2003)<\/a><\/p>\nPodobn\u00fd probl\u00e9m za\u010dali v\u00fdrobci aut \u0159e\u0161it pot\u00e9, co se motory v p\u0159\u00eddi oto\u010dily o devades\u00e1t stup\u0148\u016f (tedy nap\u0159\u00ed\u010d) a p\u0159evodovka na\u0161la m\u00edsto vedle nich. Pro Volkswagen Golf III tak bylo rozhodnuto nab\u00eddnout alternativn\u011b tak\u00e9 \u0161estiv\u00e1lcov\u00fd motor, co\u017e bylo v t\u00e9 dob\u011b v kompaktn\u00ed t\u0159\u00edd\u011b unikum (ve stejn\u00e9m roce ale Mazda uvedla motor 1.8 V6 v kup\u00e9 MX-3, co\u017e byl tak\u00e9 kompakt). Aby se motor o objemu 2,8 nebo 2,9 litru spolu s p\u0159evodovkou ve\u0161el nap\u0159\u00ed\u010d p\u0159ed p\u0159edn\u00ed poh\u00e1n\u011bnou n\u00e1pravu, bylo t\u0159eba ud\u011blat jej co mo\u017en\u00e1 nejkompaktn\u011bj\u0161\u00ed. U VW si vzpomn\u011bli, \u017ee kdysi Lancia vyr\u00e1b\u011bla vidlicov\u00e9 motory s \u00fazk\u00fdm rozev\u0159en\u00edm \u0159ad v\u00e1lc\u016f. Rozhodli se tak opr\u00e1\u0161it p\u016fvodn\u011b italsk\u00fd koncept a v\u00fdsledkem byl motor VR6.<\/p>\n
Ob\u011b \u0159ady v\u00e1lc\u016f sv\u00edraly ostr\u00fd \u00fahel 15 stup\u0148\u016f, tak\u017ee osy soum\u011brnosti v\u00e1lcov\u00fdch jednotek se prot\u00ednaly pod klikov\u00fdm h\u0159\u00eddelem. V bloku byly v\u00e1lce um\u00edst\u011bny \u201ecik-cak\u201c a z\u00e1rove\u0148 si motor vysta\u010dil pouze s jednou hlavou.<\/p>\n
Dva v jednom<\/p>\n
Koncem 90. let m\u011bl Volkswagen velk\u00e9 pl\u00e1ny, jejich\u017e sou\u010d\u00e1st\u00ed byly luxusn\u00ed auta, stejn\u011b jako supersportovn\u00ed vozy p\u0159evzat\u00e9 zna\u010dky Bugatti. Oboje pot\u0159ebovalo nov\u00e9 pokud mo\u017eno v\u00edcev\u00e1lcov\u00e9 motory. Volkswagen tak na za\u010d\u00e1tku mil\u00e9nia p\u0159edstavil nezvykl\u00e9 agreg\u00e1ty s uspo\u0159\u00e1d\u00e1n\u00edm v\u00e1lc\u016f do tvaru p\u00edsmene W. Z\u00e1hy tak vznikl osmiv\u00e1lec, dvan\u00e1ctiv\u00e1lec a dokonce tak\u00e9 \u0161estn\u00e1ctiv\u00e1lec. Posledn\u011b jmenovan\u00fd byl vyhrazen\u00fd pro pohon hypersportu Bugatti Veyron.<\/p>\n
P\u0159i konstrukci motor\u016f s v\u00e1lci uspo\u0159\u00e1dan\u00fdmi do W se vy\u0161lo z p\u016fvodn\u00edho motoru VR6. \u0160lo o modul\u00e1rn\u00ed motory. Teoreticky nejsnaz\u0161\u00ed bylo vytvo\u0159it dvan\u00e1ctiv\u00e1lec. Vznikl spojen\u00edm dvou motor\u016f VR6 se spole\u010dnou klikovou sk\u0159\u00edn\u00ed. Zachov\u00e1n z\u016fstal \u00fahel rozev\u0159en\u00ed jedn\u00e9 \u0159ady v\u00e1lc\u016f 15 stup\u0148\u016f. \u00dahel obou \u0159ad \u010dinil u W8 a W12 72 stup\u0148\u016f a \u0161lo o kruhovou v\u00fdse\u010d m\u011b\u0159enou mezi osami symetrie obou \u0159ad v\u00e1lc\u016f.<\/p>\n
Ubr\u00e1n\u00edm \u010dty\u0159 v\u00e1lc\u016f (tedy dvou z ka\u017ed\u00e9 \u0159ady) vznikl men\u0161\u00ed W8, kter\u00fd byl ur\u010den\u00fd pro pohon vrcholn\u00e9 verze Volkswagenu\u00a0Passat\u00a0B5 jednodu\u0161e ozna\u010der fn\u00e9 W8 s pohonem v\u0161ech kol 4Motion od roku 2001. Na prvn\u00ed pohled to vypad\u00e1 jednodu\u0161e, ve skute\u010dnosti to ale zase tak jednoduch\u00e9 nebylo.<\/p>\n T\u0159eba konstrukce klikov\u00e9ho h\u0159\u00eddele je pro motor W8 a W12 odli\u0161n\u00e1, co\u017e dokazuje jin\u00e9 vyosen\u00ed ojni\u010dn\u00edho \u010depu. U W8 bylo m\u00ednus 18 stup\u0148\u016f, kde\u017eto u dvan\u00e1ctiv\u00e1lce naopak plus 12 stup\u0148\u016f. Z toho tak\u00e9 vypl\u00fdv\u00e1 odli\u0161n\u00e9 po\u0159ad\u00ed zapalov\u00e1n\u00ed, kter\u00e9 bylo u W8 1-5-4-8-6-3-7-2, zat\u00edmco u W12 1-12-5-8-3-10-6-7-2-11-4-9. Naproti tomu t\u0159eba vrt\u00e1n\u00ed v\u00e1lc\u016f a tak\u00e9 zdvih p\u00edst\u016f z\u016fstaly stejn\u00e9 \u2013 84 mm (vrt\u00e1n\u00ed), respektive 90,168 mm (zdvih).<\/p>\n Motory ale m\u011bly je\u0161t\u011b jednu technickou odli\u0161nost. Men\u0161\u00ed W8 vy\u017eadovalo pro zachov\u00e1n\u00ed po\u017eadovan\u00e9 kultivovanosti chodu a kompenzaci setrva\u010dn\u00fdch sil dvojici vyva\u017eovac\u00edch h\u0159\u00eddel\u016f. Ty byly vedeny t\u011bsn\u011b nad sebou pod jednou \u0159adou v\u00e1lc\u016f. Pohon spodn\u00edho zaji\u0161\u0165oval kr\u00e1tk\u00fd ozuben\u00fd \u0159emen p\u0159\u00edmo od klikov\u00e9 h\u0159\u00eddele, horn\u00ed byl poh\u00e1n\u011bn od n\u011bj p\u0159es ozuben\u00e9 soukol\u00ed.
