1. Faulty LPI injector.2. Corrupted injector emulation circuit inside the LPE ECU.

Extracting the pump module requires emptying the tank entirely using an approved LPG recovery station. Once removed, inspect the internal fluid window. If fluid is discolored or low, the pump requires a formal bench overhaul or replacement. 3. Injector Cleaning Profile (As Needed)

The technical manual moves away from conventional terms like "vaporizer" or "mixer," replacing them with high-pressure fluid dynamic parts. The layout typically features these components:

, and particulate matter compared to petrol or older LPG systems. lpi vialle technical manual top

Liquid Propane Injection systems require minimal but highly precise maintenance. Because liquid LPG acts as a solvent, any impurities or heavy ends (paraffins/oils) within the fuel can wash through the lines and settle inside critical tight-tolerance components.

LPI Vialle Technical Manual: A Comprehensive Guide to Liquid Propane Injection

Below is an article-style technical overview of the Vialle LPi system, structured like a condensed technical manual to help you understand the architecture, key components, and maintenance requirements. Extracting the pump module requires emptying the tank

Install an LPG-compatible fluid pressure gauge (rated up to at least 25 bar) inline to the service port located on the fuel rail assembly.

While I can’t directly provide the PDF, here are the most useful practical features and where to find the official technical manual for the system:

The Vialle LPi (Liquid Propane Injection) system represents a significant shift from traditional vapor-based LPG systems by injecting fuel in a liquid state directly into the intake manifold 1. System Overview and Core Components

1. Defective LPI Pump Relay.2. Seized or open-circuit LPI tank pump.3. No RPM signal to LPI ECU.

However, because the system operates under high pressure and relies on dedicated electronic and hydraulic subsystems, diagnostic and repair work requires specialized technical knowledge. This comprehensive manual compiles essential technical specifications, diagnostic procedures, wiring schematics, and troubleshooting steps for automotive technicians and advanced DIY mechanics working on Vialle LPI systems. 1.
