An electronic emulator that intercepts petrol injection signals and translates them into corresponding liquid LPG injection times. ⚙️ Operational Mechanics
By keeping the fuel in a liquid phase, the Vialle LPI system optimizes thermal efficiency, eliminates power loss common in older gas conversions, and uses the vehicle's factory engine electronics for highly accurate fuel metering. 🛠️ System Architecture and Core Components System pressure should remain steadily above ambient LPG
The vehicle's original engine control unit operates as if the car is still running on petrol. The intercepts the fuel injector signals, calculates the density differences between petrol and liquid LPG, and adjusts the opening time of the gas injectors accordingly. 3. Cooling Effect

The technical manual provides specific procedures for system evaluation, diagnostics, and repairs: Key Diagnostic Parameters
The "Pump Tank Combination" (PTC) is fully submerged inside the tank's Multivalve. It circulates the liquid fuel at a constant pressure through the fuel lines and back to the tank.
Perform soap-bubble leak tests; verify correct torque on fittings. Low fuel level or low system operating pressure. Inspect the Multivalve level sensor and pump performance. ⚠️ Essential Safety Precautions Lpi Vialle Technical Manual
