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
High-priority grounding is typically required at the front of the engine using M6 nuts. lpi vialle technical manual top
These are mounted directly into the intake manifold, often using specific adapters to ensure the correct discharge angle toward the intake valves.
A standard Vialle LPi installation consists of several critical hardware units integrated into the vehicle's fuel and electrical systems: Unlike vapor injection systems that require a vaporizer
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.
Technical manuals like the Vialle LPi LPE-7 Assembly Manual provide strict guidelines for electrical integration: A standard Vialle LPi installation consists of several
Maintains a constant system pressure of 5 bar above the current tank pressure to prevent vapor bubbles from forming in the lines.
