si care ar fi recomandarea ta? :)

sau aici :) http://i469.photobucket.com/albums/rr51/staddly_bear/Fig2.jpg eu zic ca cei sceptici sa incerce blocarea vacuumului pt a se convinge daca merita sau nu eliminarea totala a clapetelor :lol:

adoca trebioe scos furtunul de intra in piesa aia mica :) http://koti.mbnet.fi/anzafin/BMW/Imusarja/Imusarja07.jpg

bagi un surub in botul furtunului si totul e ok... :)

originale nu sunt bosch :)

am si eu o intrebare...daca clapetele nu sunt actionate de vacuum , ele sunt in pozitia deschis?! nu?! :) atunci de ce sa le mai dam jos ,cand putem sa anulam vacuumul si aia e... :lol:

pierderea se simte daca mergi pana in 2300 de ture (fara sa o calci) ...daca o calci nu simti pierderea . :)

probabil no name, ca nu au stantat nimic pe ele :)

e cel mai sfant.

raspunsul este clar si categoric : NU . :) http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=40

Care ce?! :)

hepu albastru.

se simte doar cand este foarte incarcata masina, in rest ,nu... :)

iti dai seama ca am si modelul de 4.5 si tot nu am incredere?! :)

eu zic ca este inchis cazul.. :) 1.fie o noua admisie cu 4.5mm 2.fie scoase clapetele si aia e,siguranta maxima...

si eu cred. :)

eu m-am hotarat a 3-a oara....le dau jos... :) desi cred ca am modelul nou de clapete 4.5mm la ax p.s. in plus cred ca clapetele sunt cele care fac motorul nesigur cand stau constant in 2000rot/min,are momente cand e nesigur in accelerare plecand de la 2000 constant, momente rare de altfel...si cred ca tine de treaba cu 2300rot/min si cuplul marit sub aceasta turatie ,sa nu mai vorbim de noxe..:lol:

"The best bit - the car just feels so much more responsive. Getting rid of the flaps seems to have also got rid of the flat spots! " "In fact I am so happy with the results that I no longer intend to have the car remapped. That way I won't have to worry about the problems that come with remapping - higher exhaust gas temperatures causing premature failure of injectors and cats as well as the extra strain on the rest of the car. Saved money on the manifold and now don't want to remap - should be a good Christmas this year!"

uite rolul clapetelor.. "ĂŽn principal pentru cuplu ĂŽmbunătăţit ĂŽn gama inferioară rev şi de control al emisiilor, de obicei de mai jos cu privire la 2300 rot / min" deci prin inlaturarea clapetelor pierzi din cuplu la turatii pana in 2300rot/min :) "Astfel, de admisie a aerului intră ĂŽn cilindrul numai prin portul de turbulenţă, creând o viteză de aer de mare debit şi un vârtej puternic. Acest lucru ĂŽmbunătăţeşte amestecul de combustibil injectat cu aer şi, prin urmare de ardere."

Aici au cedat doua clapete in acelasi timp...deci , mai mult ca sigur avea probleme pe partea de actionare a clapetelor, fie din cauza jegului fie din cauza vacuumului... dubioasa insa pozitia pistoanelor...toate jos..!? :) http://i214.photobucket.com/albums/cc209/3wheeler8/italianjob-2.jpg ceva din modul de functionare.. http://i76.photobucket.com/albums/j35/Peterflux/BMWSwirlControl.jpg BMW AG BMW Diesel.... 12th DEER Conference, August 20-24, 2006, Detroit Combustion Chamber Configuration. Left Figure: 6-Cylinder Right Figure: 8-Cylinder Part of the package for EU 4 emission regulations. - Central injector position - 4 valves - Symetrical combustion chamber - Variable air control http://i76.photobucket.com/albums/j35/Peterflux/DieselSwirlControl.jpg If you read up on the technical reasons... basically for improved torque in the lower rev range and emissions control, typically below about 2,300rpm. As autos work more in the lower rev range makes sense why the 6-pot autos have them. Petrol engines also have swirl control, (emission based) it does improve combustion. Don't go down any odd road of obscure reasoning, they are there to meet emission targets. And improve running. FACT.

ia uite aici...ceva straniu a comandat codul nou, toate sunt stickarite cu codul nou ,insa pe admisia noua terminatia este din codul vechi... :) adica  7787318 "That was the whole point I queried with BMW, I ordered 11617800577, the recipt says 11617800577, the box is labelled 11617800577, But there is a sticker on the manifold itself saying 7787318." p.s. DECI DUPA FOITA LIPITA PE ADMISIE VEZI CE COD ARE :lol: "Looks the same except for an 07 manufacturing date. 'Administrative change' looks likely. Also got to bear in mind that the part number changed in 2005, that was probably before manifolds started failing, so the change has nothing to do with failures."

oricum si in pozele lui DanS , aia zic ca e bine sa le scoti ,iar ca si cauza vor creste nesemnificativ noxele...cred ca am sa renunt si eu la ele am deja destule informatii cum ca nu este afectat cu nimic motorul si functionalitatea sa... :)

ma intereseaza ,ca am cumparat masina de noua in 02.01.2005 ,ea dupa serie zice ca e din 09.2004...si na..o avea admisia noua sau cea veche?! o avea seria pe ea?! sau tre sa masor axul :)

cica : But the part number has changed. INTAKE MANIFOLD WITH FLAP CONTROL up to 07/2005 ,11617787318 ENDED. Replaced by INTAKE MANIFOLD WITH FLAP CONTROL 11617800577 deci dupa a 07/2005 s-a schimbat codu' ?! :)

apropo de schimbarea codurilor. cica cod vechi 11617787318 4mm ,cod nou 11617800577 4.5mm . http://bavarian-board.com/forum_posts.asp?...=1&get=last http://bmwland.co.uk/talker/viewtopic.php?p=526505 plus http://www.bimmerforums.co.uk/forum/f3/bmw...rl-flaps-t5537/ BMW have made the spindle stronger by using 4.5mm rod instead of 4mm rod, as found on around April 2004 manifolds. a mea este 09.2004 Swirl flap failure. Swirl flap failure being reported on BMW diesel engines including later models, less than 10000 miles reported. When the swirl flaps fail they usually break through the metal shaft where the screw/rivet goes through, these then drops into the inlet port and either jam the valve open and the piston smashes against the valve or they drop into the engine, this can cause the piston bore to become badly scored and the piston top can be damaged from the parts embedding themselves in the piston, it's also known that parts can go back up through the open valve and into another cylinder.
