Vialle LPi (Liquid Propane Injection)

The system is a sophisticated autogas solution that injects LPG in its liquid state directly into the intake manifold . Unlike older vapor-based systems, it mirrors the operation of a modern petrol injection system to maintain engine performance and reduce emissions. Core System Architecture

1. Precise Torque Specifications: Over-tightening a reducer bolt can crack the aluminum housing. Under-tightening causes gas leaks. The manual provides exact Newton-meter values.
2. Hydraulic Schematics: Understanding the coolant flow (to heat the reducer) and LPG flow is vital. The manual includes color-coded diagrams.
3. Electrical Pinouts: The Vialle ECU uses specific pin configurations. The manual details every sensor (pressure, temperature, lambda) and actuator (injectors, pump).
4. Calibration Procedures: Step-by-step instructions for the Vialle software, including offset learning and pressure mapping.
5. Safety Interlocks: LPI systems require specific safety cut-offs (e.g., crash sensor, RPM signal). The manual outlines legal and functional requirements.

Synthetic Fuel Lines:

Standard lines have a high bursting pressure (345 bar), though copper pipes may be used in specific markets to meet local regulations. Diagnostic & Maintenance Procedures lpi vialle technical manual top
