Acts as the central hub for fuel distribution, connecting the supply lines to the injectors and the pressure regulator.
Connections are usually made directly to the battery positive terminal at the fuse/relay box, using soldered eye terminals for stability. 4. Troubleshooting and Maintenance Dedicated LPG? - The 'E' Type Forum
The LPE-7 unit uses internal relays to interrupt the original petrol injectors when operating on LPG. It employs 100 Ohm resistors as "dummy loads" to prevent the vehicle's original ECU from triggering diagnostic fault codes. lpi vialle technical manual top
By injecting liquid LPG at the inlet valve, the system benefits from a "phase-change cooling effect" that prevents overheating and maintains high volumetric efficiency.
A cabin-mounted interface (often a Combi-switch) that allows manual switching and provides tank level readouts. 3. Electrical and Wiring Specifications Acts as the central hub for fuel distribution,
These are mounted directly into the intake manifold, often using specific adapters to ensure the correct discharge angle toward the intake valves.
The steel tank contains an internal diaphragm pump that circulates liquid LPG through the system. Troubleshooting and Maintenance Dedicated LPG
Technical manuals like the Vialle LPi LPE-7 Assembly Manual provide strict guidelines for electrical integration:
A standard Vialle LPi installation consists of several critical hardware units integrated into the vehicle's fuel and electrical systems:
Unlike vapor injection systems that require a vaporizer or "reducer" to heat the gas, the Vialle LPi system maintains the LPG in liquid form throughout the entire fuel cycle.
