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.
An electronic emulator that intercepts petrol injection signals and translates them into corresponding liquid LPG injection times. ⚙️ Operational Mechanics lpi+vialle+technical+manual
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
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. Positioned directly at the engine's intake valves to
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.
