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

Wire harnesses and fuse holders—typically situated in the engine compartment—must be moisture-sealed to prevent voltage drops or system dropouts. Common Faults and Solutions Probable Cause Manual Recommendation Rough running / Misfires Clogged liquid gas injectors or bad LPG fuel quality. Clean or replace injectors; check fuel rail pressure. No pump noise at start Blown fuse or faulty PTC pump motor. lpi+vialle+technical+manual

The fundamental goal of the Vialle LPi system is to mimic the vehicle's original petrol delivery as closely as possible. 1. Liquid Circulation By keeping the fuel in a liquid phase,

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. Clean or replace injectors; check fuel rail pressure

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.
