Presne ako v\u00a0pr\u00edpade predo\u0161l\u00e9ho motora, aj tu sa o\u00a0vysokotlakov\u00fd re\u017eim prep\u013a\u0148ania staraj\u00fa dve men\u0161ie turbod\u00fachadl\u00e1 v\u00a0spolo\u010dnom puzdre. P\u00f4vodn\u00e9 jedno ve\u013ek\u00e9 n\u00edzkotlakov\u00e9 turbod\u00fachadlo v\u0161ak bolo nahraden\u00e9 dvoma men\u0161\u00edmi a\u00a0t\u00fdm p\u00e1dom r\u00fdchlej\u0161ie reaguj\u00facimi. K\u00a0tomu sa prid\u00e1va najnov\u0161ia gener\u00e1cia digit\u00e1lnej naftovej elektroniky DDE (Digital Diesel Electronics), zodpovedn\u00e1 za mana\u017ement motora, vr\u00e1tane presnej aktiv\u00e1cie a koordin\u00e1cie jednotliv\u00fdch turbod\u00fachadiel, poz\u00edcie vysokotlakov\u00fdch turb\u00edn syst\u00e9mu variabilnej geometrie, regul\u00e1cie distribu\u010dn\u00fdch kan\u00e1lov a\u00a0klapiek, \u010dinnosti regula\u010dn\u00e9ho ventilu v\u00fdfukov\u00e9ho potrubia, obtokov\u00e9ho ventilu a\u00a0chladenia stla\u010den\u00e9ho vzduchu.<\/p>\n
Obe n\u00edzkotlakov\u00e9 turbod\u00fachadl\u00e1 a\u00a0jedno z\u00a0dvoch vysokotlakov\u00fdch turbod\u00fachadiel s\u00fa v\u00a0\u010dinnosti takmer neust\u00e1le. Iba pri prudkej akceler\u00e1cii z\u00a0pokoja syst\u00e9m klapiek a\u00a0kan\u00e1lov ob\u00edde obe n\u00edzkotlakov\u00e9 turbod\u00fachadl\u00e1. To umo\u017en\u00ed r\u00fdchlej\u0161\u00ed n\u00e1rast plniaceho tlaku. Druh\u00e9 vysokotlakov\u00e9 turbod\u00fachadlo vstupuje do \u010dinnosti pri dosiahnut\u00ed pribli\u017ene 2500 ot\u00e1\u010dok.<\/p>\n
\u010eal\u0161\u00edm nov\u00fdm prvkom, na rozdiel od predo\u0161l\u00e9ho motora, je recirkul\u00e1cia v\u00fdfukov\u00fdch plynov tak pre n\u00edzkotlakov\u00fd, ako aj pre vysokotlakov\u00fd stupe\u0148 prep\u013a\u0148ania. Toto opatrenie zvy\u0161uje \u00fa\u010dinnos\u0165 turbod\u00fachadiel, \u010di\u017ee aj motora ako celku. Pom\u00e1ha to tie\u017e zn\u00ed\u017ei\u0165 emisie oxidov dus\u00edka pri vysokej z\u00e1\u0165a\u017ei. Ku zv\u00fd\u0161eniu efektivity agreg\u00e1tu prispel aj nepriamy syst\u00e9m chladenia stla\u010den\u00e9ho vzduchu s\u00a0vy\u0161\u0161ou kapacitou ne\u017e pri predo\u0161lom motore, ako aj dodato\u010dn\u00e9 chladenie pre n\u00edzkotlakov\u00e9 turbod\u00fachadl\u00e1 \u2013 prostredn\u00edctvom samostatn\u00e9ho chladiaceho v\u00fdmenn\u00edkov\u00e9ho okruhu s\u00a0ni\u017e\u0161ou teplotou, nez\u00e1visl\u00e9ho od chladenia motora, s\u00a0elektricky ovl\u00e1dan\u00fdm \u010derpadlom chladiacej zmesi.<\/p>\n
