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

The submerged PTC pump pumps the liquid LPG out of the tank to the fuel rail. Excess fuel flows back into the tank via a dedicated return valve, creating a continuous loop. This keeps the fuel lines pressurized and cold, preventing the LPG from vaporizing before it reaches the cylinders. 2. Signal Translation

The PTC pump must produce a distinct, steady hum upon ignition. High amperage indicates mechanical resistance or particle contamination. lpi+vialle+technical+manual

According to the official Vialle LPi Technical Manual , the system differs fundamentally from conventional vaporizers. Instead of dropping the fuel's pressure to turn it into gas, it continuously circulates high-pressure liquid LPG.

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 By keeping the fuel in a liquid phase,

Positioned directly at the engine's intake valves to precisely meter liquid LPG into the cylinders without the need for a traditional vaporizer.

System pressure should remain steadily above ambient LPG tank pressure to maintain fuel in its liquid state. This keeps the fuel lines pressurized and cold,

When the liquid LPG is injected into the intake manifold, it immediately expands and vaporizes. This phase change absorbs heat, cooling the incoming air charge. Cooler air has higher density, which improves engine volumetric efficiency and offsets any potential power losses. 🔍 Diagnostics and Maintenance Protocols
