Senzor presiune rampa

Sunt autodidact. Si in viata anterioara cred ca am fost mecanic ca nu vad de unde pasiunea asta

Trebuie sa mai aprofundezi ca sa crezi ca ai inteles cat de cat fenomenul..

 

Ai inteles ca variatia de presiune nu apare din cauze externe cum concluzionezi?

In rampa in turatie mare pe la 2000rpm sunt cam 700 bari (constant, fara mari variatii) la o pompa buna. De acolo injectoarele isi iau presiunea pentru camera de ardere. Ma indoiesc ca se monitorizeaza presiunea pe fiecare injector.. (nu stiu daca poti sa iti imaginezi o presiune de 6-700 bari; ce presiune enorma e acolo; presiunea aceea se transmite in toata rampa LA FEL, si e suficient. Injectoarele isi iau cat trebuie (si maresc presiunea si mai mult..) si restul e trimis (si datorita lor..) pe retur inapoi in rezervor..)
