Tekanan bahan bakar pada pipa distributor dengan pressure regulator.
PC – F1 – F2Pressure regulator
P1 = Tekanan di pipa distP2 = Tekanan di manifoldPC = Tekanan konstan
Posisi idle
PC = 2,5 barP2 = 0,5 barP1 = __ bar
PC = P1 – P22,5 = P1 – P22,5 = P1 – 0,5P1 = 2,5 – 0,5P1 = 2 bar
Posisi konstan :
PC = 2,5 barP2 = 0,2 barP1 = __ bar
Pc = P1 – P2________________________________________________________________________________________________________________________________
Dengan turbo charger
PC = ___ barP1 = ___ barP2 = ___ bar
