Ne ni treba.

A ni glih fora common raila, da je bistvo, da samo dr?i visok tlak, injektorji pa potem odpirajo vbrizg takrat, ko elektronika to zahteva?

No sej se mi je zdel, da je tak, sam nism bil 100% pa sm rajs uprasu, thx

ja je treba oz. dej v fazo ?e lahko. pumpa nima stalnega tlaka,tlak niha in kadar je v fazi se tlak vi?a kadar se odpira injektor.

Danny ni res... pumpi niha pritisk samo s tem kolk se masina vrti... Vem ker mi pritisk common raila kaze diagnostika...

eo iz enega tujega foruma (eng-tips.com):

 

The high-pressure pump on a common-rail system does only one thing ... pressurize the fuel in the fuel rail. It has nothing to do with injection timing, it just pressurizes the rail and holds the pressure at a regulated setting.

 

Injection timing on a common-rail engine is done purely by controlling the timing of the pulses to the injectors, and therefore, the only way to "adjust" it is to change the mapping in the computer. It is otherwise non-adjustable. Same situation as ignition timing in newer gasoline engines with no distributors.
