This key difference offers major advantages:
Working with liquid propane requires extreme caution. Liquid LPG expands rapidly and causes severe freeze burns upon skin contact.
Comprehensive Diagnostic Flowchart: Engine Stalls on LPG Switchover
If pressure >9 bar at idle → restricted return line or blocked filter. If pressure <4 bar → failing tank pump or filter restriction. lpi vialle technical manual top
Vialle, a Dutch manufacturer widely recognized as a global leader in LPG technology, developed the LPi system to overcome the limitations of traditional vapor-based LPG systems. The "LPi" name, standing for Liquid Propane Injection, represents a fundamental shift in how LPG is delivered to an engine.
The provides:
What is the (e.g., LPE-4, LPE-7)? What vehicle engine or make are you diagnosing? This key difference offers major advantages: Working with
: Explains the advantages of liquid injection, such as improved mixture control and the elimination of power loss. Fuel Supply Components :
The LPE intercepts the injector pulse-width signals sent by the factory petrol ECU.
: Acting as the hub between the tank and injectors, this block contains the solenoid valve and the pressure regulator , which maintains a system pressure approximately 5 bar above the current tank pressure. If pressure <4 bar → failing tank pump
The most crucial element is the pump. If the pump fails, the car will not run on LPG.
Traditional LPG systems rely on an engine-heated reducer-vaporizer to convert liquid propane into a gas before induction. The Vialle LPi system bypasses this step entirely. By injecting LPG in its liquid state, the system takes advantage of the physical properties of evaporating propane to optimize engine efficiency. The Evaporative Cooling Effect
The is not a static document. Vialle periodically releases "Technical Bulletins" and "Top Updates" that supersede older information. For instance, the early LPI pumps (VLP) had a specific filter maintenance interval (15,000 km), while the newer EVO pumps extended this to 30,000 km.
