Located on the dashboard, this interface allows the driver to select fuels and displays tank levels via an LED array. It contains an audible buzzer to alert the driver of system faults or an empty LPG tank. 4. Sequence of Operation
Mounted at the return side of the fuel rail, the pressure regulator maintains a constant differential pressure over the intake manifold pressure. It ensures that the fuel pressure in the rail stays roughly 5 bar above the vapor pressure inside the tank, preventing bubble formation in the supply loop. Any excess fuel is returned back to the tank via a dedicated return line. 3. Electrical Architecture and Signal Processing Have a specific Vialle LPI issue not covered here
