Vialle systems use a sophisticated strategy. The manual explains how the ECU monitors petrol injector duty cycle vs. LPG duty cycle. Without this calibration, the car’s OEM ECU throws "fuel trim too rich" codes.
| Component | Interval | Specification | |-----------|----------|---------------| | LPG Liquid Filter | 20,000 km | 10 µm absolute rating. Bypass valve opens at 2 bar differential | | Pump Brushes | 40,000 km | Minimum brush length: 6 mm (new: 15 mm). Resistance drift > 20% indicates wear | | Injector Coil Check | 60,000 km | Measure resistance at 20°C: ( 1.7 \pm 0.1 \Omega ). If <1.4(\Omega), shorted; if >2.2(\Omega), open winding | | Rail Pressure Sensor Calibration | Annually | Zero offset with pump off: should read 0.54V ±0.05V at atmospheric 1 bar |
When liquid LPG is injected into the intake port, it instantly vaporizes. This phase change from a liquid to a gas has a powerful cooling effect on the incoming air charge, effectively acting as an internal intercooler. This denser air charge allows for more efficient combustion, resulting in performance characteristics nearly identical to petrol and minimal power loss. The system is also designed to work effectively in extremely cold environments, with certification for operation at -40°C without requiring a reducer or vaporizer.
The technical manual is a specialized guide for maintaining and troubleshooting one of the most advanced LPG autogas systems. Unlike traditional evaporative systems, the LPi system injects liquid propane directly into the intake manifold, requiring specific procedures for its unique components like the high-pressure pump and liquid injectors.

The PCU keeps the fuel line pressure consistent to prevent vaporization.
A professional Vialle LPi installation is a multi-stage process that integrates the LPG system with your car's original systems.
The Ultimate Guide to the Vialle LPi Technical Manual: Mastering Liquid Propane Injection
The LPI rail looks similar to a common rail diesel setup. It acts as an accumulator, dampening pressure pulses from the pump and supplying liquid LPG to the injectors at a stable pressure. Vialle systems use a sophisticated strategy
"Patience," Elias muttered, adjusting the focal lens of his magnification visor. "The logic board isn't fried, Kael. It’s just... forgotten."

When liquid LPG (60% Propane, 40% Butane) is injected at 5 bar and ( 20^\circ C ) into an intake manifold at 0.5 bar absolute, the pressure drop causes immediate vaporization. Without this calibration, the car’s OEM ECU throws
Most modern tech was modular—sealed black boxes designed to be swapped, not repaired. But the Vialle systems were different. They were the last gasp of an era that believed in the sanctity of the internal combustion process. They were intricate, fluid, and stubborn.
The system represents one of the most advanced LPG autogas technologies available for internal combustion engines. Unlike traditional vapor-phase systems, Vialle's technology injects liquid LPG directly into the intake manifold, offering superior performance, efficiency, and environmental benefits.
