Pozdrav svima.
Ima li neko da zna dimenzije precnika creva dovoda vazduga za turbinu kod Alfe 166 2.4 JTD 2002 godiste?
Cemu sluzi plasticna kutija koja se konektuje na sredini tog istog creva sa donje strane?
Moze li da se kutija izbaci iz upotrebe a da se dve rupe zacepe?

To ti je rezonantna kutija sluzi da prigusi buku pri usisu vazduha, ali ima i ulogu u odrzavanju snage na niskim obrtajima... ima dobrih tema o tome na stranim forumima, evo jedan dobar post sa AO foruma:
"It does reduce noise but that's a consequence of its real purpose - power & torque.
In engine design, the main destroyer of efficiency is the stop/start of air flow caused by the valves opening and closing. During development you chase inlet tuning to reduce this effect. These days the best designs feature a long tube to give low speed torque together with a resonator to absorb the valve pulses.
There are now some pretty good inlet tracts that manage to maintain torque for low speeds while allowing excellent power delivery at higher speeds.
Manufacturers spend months and months in engine test cells perfecting these designs. Quite frankly, removing them, is madness. I would expect a drop in power across the range but a bigger hit on torque.
Also, remember noise is energy. If you have more of it your losing something."

Lepo opisano i objasnjeno. Hvala. Ima li nagde tacan precnik dela creva koji ide na samu turbinu?
