Presiune injectie benzina

Mentionez ca masina are momente in care manifesta pierderi de putere.

Am masurat astazi presiunea la rampa de injectie si am gasit valori de 2.2-2.3 bar la relanti si ~2.9 bar cand se tureaza motorul. Sunt valori normale?

Daca a mai masurat cineva presiunea ce valori a obtinut?

Eu sti ca ar trebui sa fie in jur de 3 bar, dar asta la relanti, sau?

Va rog daca ma poate ajuta cineva cu o parere in cunostinta de cauza...

Pentru cine se mai confrunta sau se v-a confrunta cu problema asta, e pare ca e in regula, in Autodata presiunea de 3.0 +- 0.2 bar am inteles ca e masurata fara vacuum, cu furtunul de la regulator scos. Am masurat presiunea si in mers si la acceleratie am presiuea normala de 3bar.

Mentionez inca o data ca masina are pierderi de putere uneori mai ales dupa un drum mai lung.

Unele masuratori in INPA, ma preocupa valorile ROUGH la pistoanele 1 si 4. am prins motorul intr-o pasa proasta in inregistrare. Ce se intampla? Am permutat buji, schimbat fise, acelasi lucru deci nu e de acolo. Poate fi bobina, injectoare, compresie etc.?

 

 

 

Totodata si sonda lambda de dupa catalizator la care fluctueaza tensiunea masurata. Este asta o indicatie ca nu mai functioneaza in parametri catalizatorul?
