Regular replacement of the liquid filter is essential to prevent contaminants from reaching the injectors.
Install an LPG-compatible fluid pressure gauge (rated up to at least 25 bar) inline to the service port located on the fuel rail assembly.

No loss of power compared to petrol; higher octane rating (100+). Cooling effect of liquid injection prevents overheating. Complexity lpi vialle technical manual top

The LPE intercepts the injector pulse-width signals sent by the factory petrol ECU.
Vialle LPi (Liquid Propane Injection) system represents a landmark shift in automotive alternative fuel technology by injecting LPG in liquid form rather than as a vapor. This essay explores the technical foundations of the system, its core components, and the operational advantages detailed in its official technical manuals. The Evolution of LPG Injection Regular replacement of the liquid filter is essential
Interfaces with the vehicle's original sensors (crankshaft, throttle position) to precisely meter fuel based on engine load.
Loss of RPM signal or failure to establish a stable communication link with the petrol injection system.
This key difference offers major advantages: Switch Indicators No loss of power compared to
Unlike vapor systems that utilize large vapor filters, the LPI system relies on a high-pressure liquid filter typically integrated into the tank valve assembly or placed inline along the chassis rail.
The manual excels in its breakdown of the physical components.
