Electromagnetic solenoid valves mounted near the engine's intake ports. These injectors spray liquid LPG directly into the intake manifold, positioned as close as possible to the intake valves for optimal fuel delivery.
Each entry includes potential causes, corrective actions, and preventative tips.
The assembly manual follows a logical, procedural structure:

Check the LPE ECU flushing timer settings and test the return line valve functionality. Insufficient fuel pressure delivery from the tank.
How to use a manometer to verify if the internal tank pump is delivering the required 5-bar (approx.) pressure over the tank pressure. The assembly manual follows a logical, procedural structure:
A typical Vialle technical manual breaks the system down into four distinct subsystems. Here is a technical overview of those components.
To avoid costly repairs (like a pump replacement), the technical manual suggests a strict maintenance schedule:
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

The manual details three distinct operating phases managed autonomously by the LPE ECU:
It was a —liquid propane injection, a marvel of Dutch engineering when it worked, and a cryptic puzzle when it didn't. For three days, the car had refused to switch from petrol. The fuel pump stayed silent, a dead weight in the tank.
The pump is submerged directly in the liquid LPG, using the fuel itself for cooling and lubrication. Fuel Supply and Return Lines
For mechanics, tuners, and automotive students searching for a , the search often represents a desire to understand the "Blue Power" legacy—specifically how the company solved the thermodynamic puzzles of injecting liquid gas directly into an engine.
