: 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.
Specifically designed to inject liquid propane directly into the engine’s intake ports. lpi+vialle+technical+manual

: The electronic control unit (LPE) uses a modular motherboard with brand-specific engine data to manage fuel quantity, valves, and the fuel pump without disrupting the original engine management system.
Unlike conventional LPG systems that convert propane to gas before injection, the LPi system maintains the LPG in a liquid state until it is injected into the intake manifold. The Vialle LPi technical manual explains that this liquid state provides a cooling effect on the incoming air, increasing its density and thereby enhancing engine efficiency and power output, often matching or exceeding gasoline performance.
