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
