The system represents a significant shift in LPG technology, moving away from traditional vaporizers to a system that injects LPG in its liquid form directly into the engine's intake valves. This "liquid phase" approach allows for more precise fuel metering, mirroring the behavior of modern petrol injection systems to maintain engine performance without power loss. Core Components of the LPi System
The Vialle LPi (Liquid Propane Injection) system is a 5th-generation technology that injects LPG directly into the intake manifold using a high-pressure pump to improve cylinder filling, with the LPE control unit managing injection. Key installation components include a specialized tank pump, a coupling block, and high-precision V17 injectors, detailed further in the Vialle LPi LPE-7 Assembly Manual Motor-Talk lpi vialle technical manual top
High-priority grounding is typically required at the front of the engine using M6 nuts. The system represents a significant shift in LPG
The LPE-7 unit uses internal relays to interrupt the original petrol injectors when operating on LPG. It employs 100 Ohm resistors as "dummy loads" to prevent the vehicle's original ECU from triggering diagnostic fault codes. Key installation components include a specialized tank pump,
