am de un an un r21 motor f3n cu injectie multipunct
rasfoind manualul am vazut ca "lipit" pe quloasa dseasupra de bujiile 2si 3 se afla un sensor numit "knock sensor" care la mine observ ca lipseste ......si sigur era candva ca este (in aer) mufa care venea la el
daca stie cineva sa-mi explice si mie cam ce rol are sau daca are cineva de vanzare asa ceva ca mam tot uitat pe site-uri si nu gasesc prin oferte asa ceva
va multumesc!

http://en.wikipedia.org/wiki/Engine_knocking

In functie de informatia furnizata de knock sensor se regleaza avansul. Marturisesc ca sunt curios cum naiba a mers la tine masina corect fara senzorul ala.

De nou, el este destul de scump - pe la 300 de lei. La SH il vei gasi cu siguranta pentru cateva zeci de lei.

QUOTE
Engine knocking has disastrous consequences for the engine, since it leads to the catastrophical wear of the combustion chamber walls, through particle wear for moderate knocking, to welding for serious knocking. This is due to the contact between those walls and high temperature gases resulting from the unwanted explosion. The processes also lead to a 'knocking' noise for the engine, that give its name to the phenomenon

ms pentru info o sa caut la sh senzoru ala
de cand am masina numa acum observ ca lipseste senzoru ala

cand pornesc motorul am putere mai mare ca si dupa sa zicem jumat de ora de rulaj......oricum ceva efect trebuie sa aiba

o sa pun curand o poza sa se vada unde trebuia sa fie senzoru
dar fara asta se pare ca mere motoru si mere bine
oricum am vazut la altcineva de are masina identica cu a mea ca are senzoru
si diferenta la mers intre a mea si a lui nu se simte
