Lpi Vialle Technical Manual Top -

Unlike vapor injection systems that require a vaporizer or "reducer" to heat the gas, the Vialle LPi system maintains the LPG in liquid form throughout the entire fuel cycle.

By injecting liquid LPG at the inlet valve, the system benefits from a "phase-change cooling effect" that prevents overheating and maintains high volumetric efficiency. lpi vialle technical manual top

The system represents a significant shift from traditional vapor-based LPG conversions by injecting fuel in its liquid state directly into the intake manifold. This technical overview, derived from official assembly and technical manuals, details the system’s architecture, core components, and operational logic. 1. System Architecture and Operation Unlike vapor injection systems that require a vaporizer

Maintains a constant system pressure of 5 bar above the current tank pressure to prevent vapor bubbles from forming in the lines. This technical overview, derived from official assembly and

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.

A standard Vialle LPi installation consists of several critical hardware units integrated into the vehicle's fuel and electrical systems:

These are mounted directly into the intake manifold, often using specific adapters to ensure the correct discharge angle toward the intake valves.
