Turbodmychadlo je hodin\u00e1\u0159sk\u00fd v\u00fdrobek, to\u010d\u00ed obrovsk\u00e9 ot\u00e1\u010dky, a\u017e 250 tis\u00edc za minutu, je to extr\u00e9mn\u011b teplotn\u011b a fyzicky nam\u00e1han\u00fd d\u00edl, a proto se p\u0159i jeho v\u00fdrob\u011b postupuje s chirurgickou p\u0159esnost\u00ed a v\u011bnuje se mu mimo\u0159\u00e1dn\u00e1 pozornost. Nen\u00ed t\u0159eba se turbodmychadla b\u00e1t.<\/p>\n

P\u0159epl\u0148ovan\u00e9 benzinov\u00e9 motory te\u010f nastupuj\u00ed, p\u0159ed 20 lety je m\u011bli jen exoti, jako t\u0159eba Saab, dnes se objevuj\u00ed v\u0161ude. Pro\u010d?<\/strong> Proto\u017ee takzvan\u00fd downsizing je trend, kter\u00fd se ned\u00e1 zvr\u00e1tit. V\u00fdhody jsou jasn\u00e9 \u2013 ni\u017e\u0161\u00ed emise, ni\u017e\u0161\u00ed spot\u0159eba, ni\u017e\u0161\u00ed povinn\u00e9 ru\u010den\u00ed… Turbomotory jsou dnes i u \u0160kodovky standard. I \u201aoby\u010dejn\u00e1\u2018 fabie se 63 kW m\u00e1 turbo, stal se z n\u011bj masov\u00fd produkt. A to se t\u00fdk\u00e1 i na\u0161ich konkurent\u016f. Technicky je to v\u00fdborn\u011b zvl\u00e1dnuto, tak\u017ee nen\u00ed d\u016fvod tyhle motory do aut ned\u00e1vat.<\/p>\n

Dob\u0159e, turbo je budoucnost. Hodn\u011b se ale diskutuje o tom, jak s n\u00edm jezdit. Hlavn\u011b zda se mus\u00ed „dochlazovat“ po rychl\u00e9 j\u00edzd\u011b na d\u00e1lnici.<\/strong> Maminka v\u017edycky \u0159\u00edkala: kdy\u017e dlouho b\u011bh\u00e1\u0161, pak p\u0159es sebe n\u011bco ho\u010f, jinak se nachlad\u00ed\u0161. N\u011bkdo nastydl a jin\u00fd ne, ale t\u00edm, \u017ee tu deku p\u0159es sebe hod\u00edte, nem\u016f\u017eete nic zkazit. My doporu\u010dujeme v n\u00e1vodu, aby p\u0159i d\u00e9letrvaj\u00edc\u00edm zat\u00ed\u017een\u00ed motoru s turbodmychadlem z\u016fstal motor chvili\u010dku b\u011b\u017eet na volnob\u011bh, p\u00ed\u0161eme po dobu dvou minut. Nen\u00ed to pouze s ohledem na turbo, ale i na p\u0159eh\u0159\u00e1t\u00ed motoru, chladic\u00ed kapaliny.<\/p>\n

A i kdy\u017e turba benzinov\u00fdch motor\u016f TSI, t\u0159eba 1.8 nebo 2.0, maj\u00ed vlastn\u00ed vodn\u00ed \u010derpadlo na dochlazov\u00e1n\u00ed, hodit p\u0159es sebe deku je dobr\u00e9 i dneska, kdy\u017e m\u00e1te na sob\u011b funk\u010dn\u00ed pr\u00e1dlo, kter\u00e9 neprofoukne. U dieselov\u00fdch motor\u016f jsou samoz\u0159ejm\u011b turbodmychadla, kter\u00e1 chlazen\u00e1 vodou nejsou, ale ty zase maj\u00ed daleko ni\u017e\u0161\u00ed teploty spalov\u00e1n\u00ed ne\u017e benzinov\u00e9 motory, \u0159\u00e1dov\u011b tak o 150 stup\u0148\u016f. Samoz\u0159ejm\u011b, modern\u00ed auta jsou stav\u011bn\u00e1 tak, aby zvl\u00e1dla, kdy\u017e pojedete na maxim\u00e1ln\u00ed v\u00fdkon a pak najednou zastav\u00edte. Ale kdybyste to d\u011blal po\u0159\u00e1d, za\u010das se to projev\u00ed.<\/p>\n

Opravdu mus\u00edm \u010dekat ty dv\u011b minuty? Nesta\u010d\u00ed v praxi doba, kdy zaj\u00ed\u017ed\u00edm z d\u00e1lnice na pumpu, u\u017e bez velk\u00e9ho zat\u00ed\u017een\u00ed turba?<\/strong> Ale ano, sta\u010d\u00ed. Ochlazen\u00ed je obrovsk\u00e9, u\u017e kdy\u017e jedete bez plynu a motor se profoukne vzduchem bez paliva – teploty jdou b\u011bhem t\u0159\u00ed a\u017e deseti sekund dolu. Tak\u017ee u turbodmychadla 30 sekund \u00fapln\u011b sta\u010d\u00ed \u2013 ne\u017e dojedete na parkovi\u0161t\u011b, je to v pohod\u011b. \u0158eknu v\u00e1m p\u0159\u00edklad z praxe, jak\u00e9 extr\u00e9mn\u00ed zm\u011bny teplot b\u011b\u017en\u011b turba i v\u00fdfuky vydr\u017e\u00ed.<\/p>\n

Kdysi jsme m\u011b\u0159ili, o kolik se teplem prodlou\u017e\u00ed v\u00fdfuk p\u0159i j\u00edzd\u011b. Teploty na v\u00fdstupu z motoru jsou toti\u017e t\u0159eba kolem 800-850 stup\u0148\u016f a v\u00fdfuk se roztahuje. Nem\u011bli jsme modern\u00ed techniku a po vystoupen\u00ed z auta jsme nemohli po\u0159\u00e1dn\u011b nic nam\u011b\u0159it, jen kolem p\u011bti mm.<\/p>\n

Dneska u\u017e v\u00edm, \u017ee to bylo jako kdybychom kladivem rozb\u00edjeli atom olova… Te\u010f, kdy\u017e m\u00e1me modern\u00ed m\u011b\u0159ic\u00ed techniku, v\u00edme, \u017ee se v\u00fdfuk prodlou\u017e\u00ed o dva, dva a p\u016fl centimetru \u2013 ale mus\u00edte to m\u011b\u0159it online, v re\u00e1ln\u00e9m \u010dase. Proto\u017ee kdy\u017e s t\u00edm hork\u00fdm autem zastav\u00edte, vystoup\u00edte, ud\u011bl\u00e1te t\u0159i kroky k n\u00e1razn\u00edku, ty dva centimetry se zase smrsknou zp\u00e1tky… Tak bleskov\u00e9 to ochlazen\u00ed je \u2013 ne\u017e dobrzd\u00edte, spadne teplota o 250, 300 stup\u0148\u016f.<\/p>\n

Spousta dotaz\u016f chod\u00ed i na t\u00e9ma zaj\u00ed\u017ed\u011bn\u00ed motoru. D\u0159\u00edve se doporu\u010dovalo \u0161et\u0159it ho n\u011bjak\u00fdch p\u011bt tis\u00edc kilometr\u016f. Je to nutn\u00e9 i u modern\u00edch aut?<\/strong> Je. Ale doba zaj\u00ed\u017ed\u011bn\u00ed je krat\u0161\u00ed, do 1 500 km. Opravdu v\u0161ak doporu\u010duji dodr\u017eovat to, co je v n\u00e1vodu k obsluze. Tedy, do 1 500 km se vyhn\u011bte vysok\u00fdm ot\u00e1\u010dk\u00e1m, nejezd\u011bte na pln\u00fd plyn, nejezd\u011bte s p\u0159\u00edv\u011bsem, postupn\u011b zvy\u0161ujte z\u00e1t\u011b\u017e. Zpo\u010d\u00e1tku je toti\u017e v motoru tro\u0161ku vy\u0161\u0161\u00ed vnit\u0159n\u00ed t\u0159en\u00ed, postupn\u011b si \u201ased\u00e1\u2018, i v modern\u00edm motoru je ten efekt poznat.<\/p>\n

Po zajet\u00ed se sn\u00ed\u017e\u00ed i spot\u0159eba. Ale je dobr\u00e9 si uv\u011bdomit, \u017ee je spousta v\u011bc\u00ed, kter\u00e9 byste motoru nem\u011bli nikdy d\u011blat, proto\u017ee mu ubli\u017euj\u00ed. T\u0159eba ho vyt\u00e1\u010det v zim\u011b za studena. Olej je tuh\u00fd, maz\u00e1n\u00ed lo\u017eisek je zt\u00ed\u017een\u00e9, a motoru v tu chv\u00edli d\u00e1v\u00e1te neuv\u011b\u0159iteln\u00e9 r\u00e1ny \u2013 je to jako byste s n\u00edm najeli nav\u00edc 20 000 km. Motoru ani nesv\u011bd\u010d\u00ed vyt\u00e1\u010den\u00ed do \u010derven\u00e9ho pole – m\u00e1me sice omezova\u010de, ale kdy\u017e nemus\u00edm, tak ho netr\u00e1p\u00edm.<\/p>\n

A co \u00fabytek oleje v motoru \u2013 je to norm\u00e1ln\u00ed?<\/strong> Kdy\u017e je to do p\u016fl litru na 1 000 km, a zejm\u00e9na v dob\u011b z\u00e1b\u011bhu, pova\u017eujeme to za akceptovateln\u00e9. Po 5 000 km se spot\u0159eba stabilizuje, m\u011blo by to b\u00fdt o dost m\u00e9n\u011b ne\u017e ten p\u016fllitr. \u017de olej ub\u00fdv\u00e1, je logick\u00e9, ztr\u00e1c\u00ed se na t\u0159ec\u00edch ploch\u00e1ch v\u00e1lc\u016f, odvzdu\u0161n\u011bn\u00ed karteru, n\u011bco mali\u010dko p\u0159es turbodmychadlo… v n\u00e1vodu to popisujeme.<\/p>\n

Ale tro\u0161ku alibisticky, ne? S p\u016fllitrem na tis\u00edc km jsem se v praxi nesetkal. A to t\u0159eba Opel p\u00ed\u0161e 1 litr na 1 000 km…<\/strong> Ne\u0159ekl bych, \u017ee je to alibismus, je to sp\u00ed\u0161e proto, \u017ee ka\u017ed\u00fd z milionu z\u00e1kazn\u00edk\u016f m\u00e1 jin\u00fd styl j\u00edzdy, a ten m\u00e1 na spot\u0159ebu oleje velk\u00fd vliv. Kdy\u017e motor provozujete ve vysok\u00fdch ot\u00e1\u010dk\u00e1ch, bude i \u201a\u017er\u00e1t\u2018 v\u00edc oleje. A kdy\u017e jsme u oleje \u2013 v\u011bt\u0161ina lid\u00ed v\u00ed, \u017ee jeho hladina nesm\u00ed klesnout pod minimum na m\u011brce, ale t\u0159eba netu\u0161\u00ed opak. I nad maximum je to \u0161patn\u011b, hodn\u011b to motoru u\u0161kod\u00ed \u2013 olej se m\u016f\u017ee dostat do katalyz\u00e1toru a jin\u00fdch citliv\u00fdch oblast\u00ed, a ty zni\u010dit.<\/p>\n

Motory se v tomhle sm\u011bru staly citliv\u011bj\u0161\u00edmi ne\u017e d\u0159\u00edv, kdy nem\u00edvaly odlu\u010dova\u010de a katalyz\u00e1tory. Prost\u011b spr\u00e1vn\u00e9 mno\u017estv\u00ed oleje hraje velkou roli u \u017eivotnosti motoru. A nikdo by to nem\u011bl nech\u00e1vat jen na servisu, hladinu si ka\u017ed\u00fd mus\u00ed hl\u00eddat s\u00e1m.<\/p>\n
