Main power is drawn directly from the battery via a heavy-duty relay, protected by a dedicated 15A or 20A fuse. 4. Diagnostics and Error Code Breakdown
Intercepts petrol injector signals and translates them into modified pulse widths for LPI injectors.
Understanding the Vialle LPI system requires shifting away from traditional vapor-based LPG mindsets. The LPI system keeps the propane under constant high pressure throughout its entire loop to prevent the fuel from boiling into a gas before it reaches the cylinders. The Fuel Loop Architecture
Because the gas is injected in liquid form, it behaves closely to petrol, resulting in similar power output. lpi vialle technical manual top
Positioned in the high-pressure liquid line between the tank and the engine bay, this high-capacity filter traps microscopic particulates and heavy-end contaminants common in commercial LPG autogas. It prevents debris from fouling the precision internals of the injectors. The LTC Fuel Rail and Liquid Injectors

This article serves as a top-level overview of the LPI Vialle technical manual, covering key components, operational principles, and essential maintenance practices required to ensure peak performance. 1. What is the Vialle LPI System?
If you’d like, I can help you interpret a specific section if you share an image of the component or error code.
When the engine is running on LPG, this return valve must be fully energized and open to allow continuous fuel circulation. Understanding the Vialle LPI system requires shifting away
The tank houses a high-pressure membrane or gear pump (often a PTC pump). This pump is submerged in the liquid fuel. It is the most critical mechanical component, ensuring the fuel pressure remains high enough to prevent the LPG from boiling in the fuel rail. The Fuel Rail and LPi Injectors
: The gas computer that converts petrol injection times into LPG injection times while correcting for parameters like battery voltage and gas pressure. Coupling Block
As the LPG changes from a liquid to a vapor upon injection, it absorbs heat from the intake air. This lowers the temperature and increases the density of the intake charge, which can lead to higher volumetric efficiency and even improved performance compared to petrol.
