Lpi Vialle Technical Manual Top Extra Quality May 2026

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

A cabin-mounted interface (often a Combi-switch) that allows manual switching and provides tank level readouts. 3. Electrical and Wiring Specifications

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

The steel tank contains an internal diaphragm pump that circulates liquid LPG through the system.

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. The system represents a significant shift from traditional

Technical manuals like the Vialle LPi LPE-7 Assembly Manual provide strict guidelines for electrical integration:

High-priority grounding is typically required at the front of the engine using M6 nuts. The steel tank contains an internal diaphragm pump

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.

The system utilizes a specialized LPE (LPi Control Unit) that mirrors the vehicle’s original petrol ECU strategy. It converts petrol injection timing into corresponding LPG timing, ensuring features like RPM limits and fuel shut-off during deceleration are preserved. 2. Core Technical Components
