Maintains a constant differential pressure above the ambient tank pressure. This ensures that even under high engine bay temperatures, the LPG cannot boil or vaporize inside the rail.

The LPE has triggered an active error code (e.g., low fuel pump pressure). Top Technical Challenges Detailed in the Manual lpi vialle technical manual top

: Liquid LPG is delivered through synthetic lines to injectors mounted on the manifold via specialized adapters.

Unlike older generations that relied on a gas/air mixer, the LPi system uses a specialized hardware suite designed for high-pressure liquid circulation. Detailed diagrams and full service procedures can be

The LPE‑7 is central to the system’s performance. It bases its calculations on the petrol injection times (in g/sec) sent by the original engine control unit. Using these inputs, the ECU calculates the optimal speed for the fuel pump, the required injection pressure, and the precise duration for the LPG injectors. The LPE‑7 uses this approach to synchronize precisely with the petrol ECU, adjusting the liquid LPG injection without interfering with the vehicle’s native diagnostic systems.

(often using FTDI chips) to communicate with the TEC unit for calibration and fault code reading. Top Technical Challenges Detailed in the Manual :

Historically, LPG systems relied on vaporizers (or reducers) to convert liquid fuel into gas before mixing it with air for combustion. The Vialle LPi system, often referred to as a "5th Generation" technology, mirrors the operation of modern petrol injection systems. By maintaining the fuel in a liquid state until the point of injection, the system eliminates the need for a vaporizer, resulting in more accurate fuel metering and improved engine performance. Core System Components

Because the fuel remains liquid until the moment of injection, it cools the incoming air charge (latent heat of vaporization), increasing volumetric efficiency.
