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
Maintains a constant system pressure of 5 bar above the current tank pressure to prevent vapor bubbles from forming in the lines.
Technical manuals like the Vialle LPi LPE-7 Assembly Manual provide strict guidelines for electrical integration: lpi vialle technical manual top
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.
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 represents a significant shift from traditional
These are mounted directly into the intake manifold, often using specific adapters to ensure the correct discharge angle toward the intake valves.
A cabin-mounted interface (often a Combi-switch) that allows manual switching and provides tank level readouts. 3. Electrical and Wiring Specifications Unlike vapor injection systems that require a vaporizer
The steel tank contains an internal diaphragm pump that circulates liquid LPG through the system.
