: Resources are available for individual components such as the Vialle LPE6.6 injector cut-off relay (which electrically switches off petrol injectors during LPG operation), the PTS-50 pump (suitable for engines up to 210 kW), V17 injectors (rated at 20–25 kW per cylinder), and cylindrical LPG tanks specifically designed for Vialle LPi and LPdi systems with large openings suitable for pump and multivalve installation.
Unlike standard tanks, the Vialle tank contains a high-pressure pump that keeps the LPG pressurized throughout the fuel lines.
The is more than a service booklet—it is the key to reliable LPG performance. As Vialle systems age, more independent shops are downloading and sharing these PDFs. However, beware of counterfeit manuals: check watermark logos and page count (legitimate Vialle LPi manual is 148 pages, including the wiring diagram appendix).
The Vialle ECU is a "master-slave" unit. It connects to the vehicle's original petrol ECU via the OBDII port or by intercepting injector signals. lpi+vialle+technical+manual
When working with LPI systems or any technical equipment, always refer to the manufacturer's guidelines and technical manuals for installation, maintenance, and troubleshooting. This ensures safety and the optimal performance of the system.
For automotive technicians, diagnostic engineers, and advanced DIY mechanics, the is an indispensable resource. It outlines the unique hydraulic logic, electrical schematics, and specialized components necessary to install, calibrate, and troubleshoot this precision alternative fuel system. System Architecture: Core Components

The system represents a major milestone in alternative fuel technology. Unlike traditional Liquefied Petroleum Gas (LPG) systems that vaporize the fuel before it enters the engine, the Vialle LPi system injects liquid LPG directly into the intake manifold. To safely service, diagnose, and maintain this advanced autogas setup, technicians and DIY enthusiasts must understand the core principles outlined in the official Vialle LPi Technical Manual . 1. What is the Vialle LPi System?
This comprehensive technical guide outlines the core architecture, operational mechanics, system components, maintenance protocols, and diagnostic workflows essential for automotive technicians and dual-fuel calibration engineers. Core Architecture and Operational Theory
Always match the part number on your injector rail (e.g., Vialle 9015-01) to the manual. As Vialle systems age, more independent shops are
The liquid pump inside the tank is a wear item. Over time, internal bearings can degrade, resulting in noise or reduced pressure capacity.
"Under no circumstances should the LPG system be activated if the petrol system has a leak. The LPI ECU monitors engine stability; if misfire count exceeds 5% over 1000 revolutions, the system shall force switch back to petrol and disable the LPG pump. Do not bypass this interlock."
To help narrow down the technical information for your specific vehicle configuration, could you provide a few more details? What is the ?
While you can often find LPi Vialle technical manuals in PDF format through educational databases or enthusiast forums, always verify that the version matches your specific LPE generation (e.g., LPE 6.x or LPE 7.x). For the most up-to-date information, the official Vialle website or authorized installers are the best primary sources. Conclusion
