The system utilizes a specialized LPE (LPi Control Unit) that mirrors the vehicle’s original petrol ECU strategy. It converts petrol injection timing into corresponding LPG timing, ensuring features like RPM limits and fuel shut-off during deceleration are preserved. 2. Core Technical Components
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.
These are mounted directly into the intake manifold, often using specific adapters to ensure the correct discharge angle toward the intake valves. lpi vialle technical manual top
Acts as the central hub for fuel distribution, connecting the supply lines to the injectors and the pressure regulator.
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. The system utilizes a specialized LPE (LPi Control
A cabin-mounted interface (often a Combi-switch) that allows manual switching and provides tank level readouts. 3. Electrical and Wiring Specifications
The "brain" of the system (common versions include LPE-7 ) which manages the switching between fuels and regulates injection duration. By injecting liquid LPG at the inlet valve,
Maintains a constant system pressure of 5 bar above the current tank pressure to prevent vapor bubbles from forming in the lines.
