: How the gas computer (LPE) processes injector signals and handles offsets.
: Direct-fit fuel injectors mounted into the engine’s intake manifold. They deliver precise bursts of liquid LPG directly onto the inlet valves.
Internal leaking (causing hard warm restarts due to rich manifold conditions) and nozzle clogging from heavy-end contaminants (paraffins) found in low-quality LPG fuel.

Vialle LPG System Troubleshooting Guide : Comprehensive list of fault symptoms and repair steps.
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
Before diving into the technical manual, it's essential to understand the basics of LPI systems. LPI is a type of fuel injection system that uses liquefied petroleum gas (LPG) as a fuel source. These systems are commonly used in industrial and commercial applications, such as forklifts, generators, and vehicles. LPI systems offer several advantages over traditional fuel systems, including reduced emissions, improved fuel efficiency, and lower operating costs.
The manual's primary value proposition is how it handles the physics of liquid injection. : How the gas computer (LPE) processes injector
The LPI Vialle technical manual is a detailed guide that covers various aspects of LPI system design, installation, operation, and maintenance. The manual is intended for technicians, engineers, and other professionals working with LPI systems, particularly those using Vialle injectors. The manual provides comprehensive information on:

The is a definitive milestone in automotive alternative fuel technology, replacing old-fashioned vaporizers with highly accurate direct liquid LPG injection . Unlike traditional vapor systems that cause performance drops, the Vialle LPi technical architecture preserves 100% of the engine's original power output , rendering it identical to running on petrol. Understanding the core diagnostic rules, component mappings, and hydraulic behaviors outlined within the official technical documentation is critical for maintaining maximum system efficiency and vehicle reliability. 🛠️ System Architecture & Mechanical Breakdown
Let’s run a real-world scenario using the manual’s decision tree.
Petrol mode active; system waiting for gas changeover delay (up to 2 minutes). Normal during engine warm-up phases.
